House flipping software: what a beginner should make it prove

Written and reviewed by the Rehabfolio editorial team. Published and last reviewed October 27, 2026.

Who this guide is for. This guide is for a beginner in the United States who is about to analyze a one-to-four-unit house to renovate and resell, or who already owns one and is deciding whether the file should leave a spreadsheet. You do not need a license, a crew, or a software budget to use the checklist. If you are still learning the purchase math, start with the first-property analysis and the 70% rule guide. If the house is already a job site, the rehab project management guide picks up after the offer.

The Rehabfolio editorial team builds and reviews the workflows this article describes: a property record, a repair estimate, a deal analysis, and a project file. That is first-hand product experience. It does not make the team a licensed contractor, broker, lender, appraiser, inspector, attorney, or accountant. We do not invent licenses, customer counts, or results. Red is the author of this guide. The card at the end states his investing background. This page does not add a city, a testimonial, or a project address to that record.

Contract forms, license rules, tax treatment, and loan draws differ by state, city, lender, and the agreement you sign. This page is educational. It is not legal, tax, lending, appraisal, or investment advice. Use the signed documents and qualified local professionals for the house in front of you.

1. Define what house flipping software is for

Beginners shop for house flipping software the way they shop for a new phone: a dashboard, a green profit number, and a promise that the messy part is handled. The messy part is the decision. You are trying to buy a house, change it, and sell it for more than the whole cost stack. Software is useful when it keeps that stack attached to one address and shows the moment a number changes. It is not useful when it only stores the slogan.

Home flipping software is the same search in different words. People type both phrases when they want a tool for a fix and flip. Neither phrase is a standard, a license, or a feature list. A product can rank for the words and still be a single calculator, a photo album, or a task board. Ask what the file can prove on a Wednesday afternoon, when a contractor changes the scope and the seller is waiting on your number.

Separate four kinds of content while you look. Observed facts are the closed sale, the bid, the permit, the invoice, and the loan note. Calculations turn those facts into a maximum offer, a daily holding cost, or a remaining budget. Assumptions are the finish month you hope for and the allowance you have not selected. Opinions are sentences like "this one feels good." A serious tool stores facts and calculations where you can audit them. It labels assumptions. It does not promote an opinion into a purchase price.

Software also has a boundary. It does not pull a permit, pass an inspection, or sign a draw. The Consumer Financial Protection Bureau describes a construction loan as a usually short-term loan used to build or rehabilitate a home, with funds typically released in advances as the work progresses. Your file can prepare the story of those advances. The note and the lender still control the release. An after-repair value typed into a screen is not an appraisal. The Appraisal Foundation publishes the standards licensed appraisers follow. An investor screen is not that product.

2. Cover five jobs: repairs, ARV, holding costs, the offer, and the project

Any house flipping system, whether it is a binder or a login, has to cover five jobs. If one job is missing, the others lie. A profit figure with no repair scope is a wish. An after-repair value with no comparable sales is a guess. A maximum offer that ignores the months you will own the house is a slogan with a dollar sign.

Rehab estimate

The rehab estimate is the cost of the work you will actually do. Write rooms, trades, quantities, and what is excluded before you trust a single total. The repair budget guide and the scope of work guide show how to build that list from a walk, not from a vibe. A calculator can hold a starting allowance. The rehab cost calculator adds an area allowance, kitchens, bathrooms, systems, exterior work, permits, and contingency. Replace every placeholder with a measured scope and a contractor price before you commit. Software that hides the lines and shows only a pretty total is hiding the job.

After-repair value

After-repair value, often shortened to ARV, is what a similar house sells for after a renovation like the one you will deliver. It is not the as-is price, and it is not your offer. Fannie Mae's selling guide section on comparable sales tells appraisers to use sales with similar physical and legal characteristics, including site, room count, finished area, style, and condition. It expects at least three closed sales, prefers the subject's market area, and asks for an explanation when the search has to move farther out. Those rules govern many mortgage appraisals. They are a sound screen for a flip even when you pay cash, because the buyer's lender may hire an appraiser who has to defend a similar set.

The companion section on adjustments is the part people skip. A larger house, an extra bathroom, a garage, a busier road, or a seller concession changes the price. If you cannot say what the adjustment was and why, you do not have an adjustment. Read the after-repair value guide before you type a value into any tool. House flipping software should store the sales you used and the reason you kept them. A single number with no sales behind it is not a value.

Holding costs

Holding costs are the financing and ownership bills that continue while you own the house, from the purchase closing toward the sale closing. Interest, taxes, insurance, utilities, and basic upkeep belong in that pile. A loan payment can contain principal, interest, escrow, and fees. The Consumer Financial Protection Bureau explains that a total monthly mortgage payment can include principal, interest, mortgage insurance, taxes, and homeowners insurance. If you label the whole payment as cost and also count taxes and insurance, you count those items twice. The holding cost guide walks the categories. The holding cost calculator turns a monthly carry into a total and a daily delay cost. Listing the house does not stop the interest.

Maximum allowable offer

The maximum allowable offer is the highest purchase price that still works after the other lines. The familiar 70% screen is a shortcut, not a law: multiply after-repair value by 0.70, then subtract repairs. Rehabfolio's deal math uses that order. Subtracting repairs first and then multiplying produces a different number, and the difference is an error, not a strategy. The 30% wedge is not pure profit. It has to cover buying, financing, holding, selling, uncertainty, and only then a profit target. The maximum allowable offer calculator compares that shortcut with a detailed ceiling that uses the costs you enter. The flip profit calculator answers a related question: given a purchase price, what profit is left. The flip analysis calculator is the fuller screen when you want the property, the value, and the cost stack in one pass. Use the screen as a ceiling, not as the opening sentence of a negotiation.

Project tracking

Project tracking starts when the offer is accepted and the house becomes a job. The file should hold the frozen scope, the budget, the dates, the photos, and the person who owns the next action. The cost breakdown guide shows how acquisition, rehab, holding, selling, and contingency sit in one profit picture. The project system is where those lines get updated after demo day. A task board with no budget is a calendar. A budget with no photos is a story. The fix and flip workflow is the path from an accepted analysis into that rehab record.

3. Decide when a spreadsheet is still the right tool

A spreadsheet is not a lesser version of house flipping software. It is a different tool with a real strength: you can see the formula. For a first flip, one person, and one house, a disciplined workbook can hold the five jobs if you update it on a schedule and you can still explain every cell. The spreadsheet alternative note and the spreadsheet comparison stay on that boundary. Do not switch because a homepage told you that sheets are messy. Switch because the sheet stopped being the record.

Stay in the sheet when all of these are true. You have one active house. You are the only person who edits the numbers. Photos and permits still fit in a folder you can find. No lender is asking for a progress packet. You can name the current after-repair value, the repair total, and the offer ceiling without opening a text thread.

Move toward a shared system when any of these become true. A second house is live. A partner, a lender, or a contractor needs the same current number. A change was done in the field before anyone wrote the cost. You cannot tell which version of the workbook is the offer you actually made. The tool does not fix a missing scope. It only gives the scope a place to live.

4. Use a buyer checklist before you pay

Use this list on a trial, a demo, or a spreadsheet. If a product cannot show the line, write "missing" and decide whether that job matters for the house you have now. Do not award points for a logo.

1. One property. The address on the offer, the repair list, the comps, and the tasks is the same address.
2. Repair lines. You can see quantities, not only a single rehab total. Unknowns are named, not blended into a round number.
3. Comparable sales. You can see at least the closed sales you relied on, and you can say why a sale was kept or dropped.
4. Holding lines. Interest, taxes, insurance, utilities, and upkeep are separate from the renovation budget. A longer timeline changes the total.
5. Two offer numbers. The 70% screen and the detailed ceiling are both visible, and they are not forced to match.
6. A project handoff. If you buy the house, the accepted scope and budget can become the job file without retyping the deal into a second product.
7. A human yes. A draft from AI, a template, or a default percentage does not overwrite your number until you accept it.
8. A price you can reread. The plan name, the monthly or annual amount, the trial rules, and what happens when the trial ends are on the vendor's own page, with the date you checked.

5. See how Rehabfolio fits those jobs

Rehabfolio is one workspace for the same five jobs. You can run the public calculators before you create an account. The rehab cost calculator, the flip profit calculator, the maximum allowable offer calculator, the holding cost calculator, and the flip analysis calculator each publish the formula on the page. Nothing in those tools is a quote from a contractor or a promise about a neighborhood.

Inside a workspace, deal analysis keeps purchase price, after-repair value, repairs, financing, holding costs, selling costs, profit, and a maximum offer on one property. The 70% rule is shown as a quick reference. The main analysis uses the costs you enter. Rehab estimating is where a scope replaces the starting allowance. Project management holds tasks, files, and photos after you own the house. The project page says the workspace is a responsive browser, including a phone browser. It does not describe a separate app-store download.

Rehabfolio's pricing page, which reads the plan catalog, lists Free at $0 with 2 active projects, Solo at $69 per month, Team at $179 per month, and Business at $349 per month. The same page says annual billing is 25% off, displayed as Solo $52 per month billed yearly ($621), Team $134 per month ($1,611), and Business $262 per month ($3,141). Paid plans include a 14-day trial, and the pricing page and the terms say a card is required at checkout. Free does not require a card. Recheck the pricing page before you rely on a dollar, because a guide can go stale and the catalog is the source.

That is a fit statement, not a ranking. If your crew will only post a job photo through a native app, a browser workspace is the wrong shape even if the math is clear. If you have one house and a workbook you trust, you may not need any login. The FlipperForce alternatives guide sorts spreadsheet, calculator, rental books, task app, and rehab workspace by the job in front of you.

6. Compare FlipperForce only where a page supports the cell

FlipperForce is a known house flipping product, so a fair guide has to mention it. This table uses two FlipperForce pages reviewed on October 27, 2026: the homepage and the pricing page. Rehabfolio cells use Rehabfolio's own pages on the same date. A cell says "Not verified" when those pages did not state the point. Do not fill a blank from memory, a review site, or an older roundup. The longer product contrast lives on FlipperForce vs Rehabfolio. Recheck both vendors before you buy. Plan names and dollars move.

Read the table as a source check, not a winner. FlipperForce's homepage also stated user and project counts and printed customer quotations. This guide does not repeat those figures or quotations. They are marketing claims on that page, not facts this editorial team counted. Rehabfolio does not publish a customer count here either. Price is a fact with a date. A lower price can also be a smaller fit. If a native field app is the job, say so and stay. If the job is a visible cost stack in a browser, say that instead.

7. Walk three illustrative investor scenarios

The three people below are teaching composites. Their names, houses, and dollars are illustrative. They are not customers, not case studies, and not prices from a city. Every arithmetic step is shown so you can redo it. Change the inputs and the decision can change.

Illustrative scenario: Amira Solis, one house, one workbook

Amira is buying her first flip, a three-bedroom ranch, and she is the only person on the file. She assumes an after-repair value of $320,000 and a repair total of $45,000. Both numbers are her assumptions for this lesson, not a market quote.

The 70% screen multiplies first. $320,000 times 0.70 is $224,000. Then subtract repairs: $224,000 minus $45,000 is $179,000. That $179,000 is a screen, not an offer. She still has no buying costs, no holding costs, and no selling costs on the page. She writes those lines into the same workbook before she calls the seller. She does not buy software yet. One house, one editor, and a sheet she can audit still meet the test in section 3. Her decision is to keep the spreadsheet until a second person or a second house makes the current number hard to find.

Illustrative scenario: Luis Ortega, two live rehabs

Luis already owns one house in renovation and is about to close on a second. For this lesson, the second house carries $4,200 a month in interest, taxes, insurance, utilities, and basic upkeep. That monthly figure is illustrative. Using a 30-day month as the teaching shortcut, $4,200 divided by 30 is $140 a day. A 15-day slip is 15 times $140, or $2,100. The first house has its own carry. This paragraph does not invent that second total.

The $2,100 is not why Luis needs a different file. He can do that multiplication on paper. The problem is that the draw photos live in a text thread, the change in the kitchen lives in a voicemail, and the workbook on his laptop is not the version his lender saw. Two live jobs fail the "one editor, one house" test. His decision is to put both addresses in one shared record, with an owner on the next action, whether that record is a stricter workbook system or house flipping software. The daily math still has to be visible. A dashboard that hides the $140 does not fix the slip.

Illustrative scenario: Nora Bennett, screen versus full stack

Nora is comparing a seller's ask with two ceilings. Her illustrative assumptions are an after-repair value of $510,000 and repairs of $88,000. The 70% screen is $510,000 times 0.70, which is $357,000, minus $88,000, which is $269,000. The ask is $295,000. The ask sits $26,000 above that shortcut. She does not walk yet. The shortcut is not the full stack.

She then writes a detailed ceiling with more illustrative assumptions: buying costs $9,000, financing $18,000, holding $12,000, selling costs $30,000, and a target profit of $70,000. Adding those to the repairs gives $88,000 plus $9,000 plus $18,000 plus $12,000 plus $30,000 plus $70,000, which is $227,000. Subtract that from the after-repair value: $510,000 minus $227,000 is $283,000. At the $295,000 ask, the gap is $12,000. The 70% screen was stricter than this particular stack because her assumed costs and profit target do not consume the entire 30% wedge. That is the lesson of the shortcut. It can be tighter or looser than the deal you actually have.

Nora's decision is to counter or walk. She does not "meet in the middle" without a new ceiling. If a walkthrough raises repairs, she reruns both numbers before she sends a price. She can do that on the maximum offer calculator without creating an account. Software did not make the decision. The visible stack did.

8. Run one deal on paper or a free calculator

You can finish a first pass without a subscription. Use a sheet of paper or the public calculators. Write the address at the top so a number from a different house cannot sneak in.

1. Write the as-is price the seller is asking, and leave the offer blank.
2. List at least three closed sales that match the finished house, or write "not chosen yet."
3. Write the after-repair value only after those sales exist. If they do not, leave the value blank.
4. List repair lines you could see, and a separate line for systems you could not see.
5. Multiply the after-repair value by 0.70, then subtract repairs. Label the result "70% screen."
6. Add buying costs, financing, holding costs, selling costs, and the profit you require. Subtract that stack from the after-repair value. Label the result "detailed ceiling."
7. If the ask is above the ceiling you trust, the next action is a lower price or a walk. If it is under, the next action is a walkthrough that can still kill the number.
8. If you buy, copy the accepted scope and budget into the project file the same day. Do not start demo from a text message.

That sequence is the worked example you can reuse. Amira stops at the screen and then fills the missing cost lines in her sheet. Luis adds a daily holding line when the date moves. Nora refuses to let the shortcut and the full stack collapse into one unlabeled "max." A product that will not let you see those labels is a poor fit, even if the homepage says house flipping software.

9. Keep AI as a draft, not the decision

Many house flipping tools now offer an AI draft: a repair list from photos, a summary of a listing, or a suggested offer. Used as a clerk, that can save a retype. Used as a decider, it can launder a guess into a number that looks finished. The AI underwriting guide is the longer version of this boundary. The short version is enough here.

A model may sort notes you already stored, draft a task list from a scope you already wrote, or flag that a photo has no room name. A person still checks the comparable sales, the quantities, the loan terms, and the walk-away price. Show the source note. Label assumptions. Require a human yes before a draft becomes the plan. Do not treat the vendor name, or the model name behind the screen, as evidence. Rehabfolio's AI disclosure states that AI output remains a draft. Read it if you want the product boundary in one place. This article does not rank model providers.

The same rule applies to a rehab number that came from a listing photo. A photo can support a preliminary scope. It cannot see inside a drain line, a roof deck, or a panel. Keep that draft out of the offer until a walk or a bid replaces it. The photo estimate guide shows the stop point.

Frequently asked questions

Editorial methodology, limitations, and sources

The Rehabfolio editorial team wrote this as the buyer's page for house flipping software and home flipping software. It does not replace the fix and flip workflow, the spreadsheet alternative, the FlipperForce comparison, the alternatives guide, or the calculator pages. Those pages remain the homes for product specifics and for each formula. This article answers a different question: what any system has to prove, when a spreadsheet is enough, and how to read one competitor without inventing a cell.

Key public sources, and the claim each one supports:

• Fannie Mae Selling Guide, B4-1.3-08, Comparable Sales. Similar physical and legal characteristics, a preference for the subject market, and the three-closed-sale expectation used in many mortgage appraisals. Cited for how to screen an after-repair value, not as a flip rule.
• Fannie Mae Selling Guide, B4-1.3-09, Adjustments to Comparable Sales. Why a sale price is not usable until differences are addressed.
• The Appraisal Foundation. Publisher of the standards licensed appraisers follow. An investor screen in software is not that appraisal.
• CFPB, What is a construction loan?. A short-term loan to build or rehabilitate a home, with funds typically released in advances as work progresses. Cited to show that software does not control draws.
• CFPB, principal and interest versus the total monthly payment. A total monthly payment can include principal, interest, mortgage insurance, taxes, and insurance. Cited so holding costs are not double-counted.
• IRS Publication 551. Basis, settlement costs, carrying charges, and capitalization. Treatment depends on the facts and the taxpayer. This guide does not tell you how to file.
• IRS, What kind of records should I keep?. A recordkeeping system should clearly show income and expenses, and supporting documents should identify the payee, amount, proof of payment, date, and description.
• HUD 203(k) program page. A public example of rehabilitation mortgage insurance that ties a work write-up, inspections, and draws together. It is not a description of every private flip loan.
• FlipperForce homepage and FlipperForce pricing. Reviewed October 27, 2026, for the comparison table only. Their user counts and testimonials are not repeated here.

Rehabfolio product statements in this article point at the pricing page, the terms, the calculator pages, deal analysis, rehab estimating, and project management. The 70% order of operations matches the public offer guide and the product's deal math: after-repair value times 0.70, minus repairs. Illustrative dollars in the three scenarios are original teaching numbers. They are not quotes, bids, or closed deals.

Public guidance cannot tell you which software to buy, how large a contingency a particular house needs, or what a city will require for one repair. Examples are composites created for teaching. Names and outcomes are illustrative. Dollar figures in the scenarios are educational, not offers.
