How to compare offers on a house flip

Published and last reviewed August 24, 2026 · Written and reviewed by the Rehabfolio editorial team.

Who this guide is for. This guide is for new and growing residential investors in the United States who have received one or more offers on a renovated one-to-four-unit property. It begins when written offers arrive and ends with a documented selection, counteroffer, rejection, or backup plan. Read the house flip pre-listing checklist first if the property facts, disclosure process, pricing evidence, or showing plan are still incomplete.

The Rehabfolio editorial team builds and reviews product workflows that connect property facts, comparable sales, scopes, estimates, photographs, files, expenses, financing, tasks, contacts, risks, reports, and sale decisions. That gives the team first-hand product experience organizing the evidence behind a house-flip exit and tracing a change through the project record. It does not make the team a broker, real-estate licensee, appraiser, lender, attorney, title or escrow professional, tax professional, insurer, inspector, or investment adviser.

Purchase contracts, deposits, disclosure, agency, appraisal, financing, counteroffer, backup-offer, fair-housing, tax, title, settlement, and possession rules vary by state and locality. Use a licensed local real-estate professional and real-estate attorney, plus qualified lending, appraisal, title, escrow, insurance, and tax professionals when appropriate. This guide is educational information, not legal, tax, appraisal, brokerage, lending, or investment advice.

1. Compare the contract package, not the headline price

An offer is a proposed exchange of price, timing, money, property, duties, and risk. The buyer may offer more while asking the seller to pay credits, accept a broad inspection exit, wait for another property to sell, leave appliances, or carry the house longer. Another buyer may offer less with fewer dependencies and an earlier closing. Neither is automatically better.

The National Association of Realtors' current consumer guide to navigating multiple offers explains that price is one of several elements and that financial terms, contingencies, closing timeline, and earnest money can change an offer's attractiveness. It also cautions that contract law varies. Use that national overview as a question list, then follow the local forms and advice supplied by the professionals on the transaction.

Keep four categories separate. Observed facts are written offer terms, dated documents, verified deposits, and completed events. Calculations apply disclosed arithmetic to those terms. Assumptions estimate unknown costs, dates, or outcomes. Opinions are judgments about execution strength, convenience, or acceptable risk. “Buyer has a dated preapproval letter” is an observed fact. “Buyer will certainly close” is not.

2. Normalize every offer before ranking anything

Preserve each original offer and addenda exactly as received. Then copy the same decision fields into a side-by-side comparison. Do not compare one buyer's full contract against another buyer's email summary. Flag blanks, conflicts, expired documents, handwritten changes, and referenced addenda that are not attached.

Scenario: Maya Chen catches a credit hidden behind the highest price.Maya receives $526,000, $520,000, and $515,000 offers. The $526,000 contract asks for a $15,000 seller credit and two appliances that Maya planned to sell separately. She records the written terms rather than labeling it the winner. Her first calculation starts at $511,000 before the appliance effect and other sale costs. The lower offers now deserve a complete comparison.

3. Calculate net proceeds with the same assumptions

Use one planning formula for every offer: offer price minus seller-paid buyer credits minus sale and settlement costs minus debt payoff minus open project costs minus carrying costs through closing equals estimated cash before taxes. Keep the source and date for each input. If a cost does not change between offers, use the same amount. If the closing date changes taxes, utilities, insurance, interest, or property care, calculate that difference.

Commissions, brokerage compensation, transfer charges, attorney fees, title or escrow costs, prorations, payoff interest, and local seller charges depend on the agreements and jurisdiction. Ask the professionals for current estimates. CFPB's current Closing Disclosure rule and official interpretation include a summary of the seller's transaction for covered mortgage closings. That final disclosure is a settlement record, not a substitute for comparing estimates before acceptance.

Continue carrying expenses through a realistic closing date. The house flipping holding-cost guide shows how financing, taxes, insurance, utilities, and property care accumulate. Keep a separate tax view. IRS Publication 551 explains that accurate records are needed for basis and that improvements generally increase basis, but a project net sheet does not determine the tax treatment of inventory, basis, expenses, or gain.

Scenario: Luis Ortega prices a 19-day timing difference. Luis compares a $610,000 offer closing in 24 days with a $616,000 offer closing in 43 days. His documented daily financing, tax, insurance, utility, and care estimate is $184. The added 19 days equal $3,496. That calculation does not prove the later buyer will take exactly 43 days, but it replaces the vague label “slow closing” with one visible assumption that can be revised.

4. Review financing strength without pretending it is guaranteed

Record the financing type, loan amount, down payment, lender contact, letter date, property address if shown, expiration, conditions, and whether the funds used for down payment, appraisal gap, and closing costs have separate evidence. Ask the listing professional what buyer information may lawfully be requested and verified in the local process. Do not request protected-class information or diagnose a buyer's finances yourself.

CFPB says that prequalification and preapproval letters describe what a lender is generally willing to lend up to a stated amount under assumptions, but neither is a guaranteed loan offer. Lenders also use the labels differently. Instead of ranking a buyer by the word at the top of a letter, have the appropriate professional review what was verified, what remains conditional, and whether the timeline fits underwriting, appraisal, title, and closing requirements.

Cash removes a mortgage contingency only if the contract actually does so. It does not remove inspection, title, legal review, proof-of-funds, transfer, deposit, or closing risk. Verify proof through the accepted local process. Do not rely on an easily edited screenshot. The seller's comparison should record that acceptable evidence was reviewed by the responsible professional, not store unnecessary account details in a broad project file.

5. Treat appraisal terms and seller concessions as real dependencies

A financed buyer's lender may require an appraisal. Fannie Mae's consumer appraisal overview explains that when appraised value is below the contract price, the lender may not approve the full requested amount. Possible responses include price renegotiation, a buyer bringing more cash, or a reconsideration process, depending on the facts and contract. The seller should not count a verbal promise to “cover any gap” unless the written agreement and reviewed funds support it.

Compare the appraisal contingency deadline, stated gap contribution, cap, evidence, termination rights, reconsideration timing, and interaction with the financing contingency. Ask what happens at several appraised values rather than treating risk as yes or no. A $620,000 offer with a $10,000 gap commitment can behave differently at appraisals of $618,000, $605,000, and $590,000.

Seller credits also interact with lending rules. Fannie Mae's current Selling Guide requires relevant financing data and sales concessions to be disclosed to the appraiser and identifies items such as settlement charges, loan fees, discounts, buydowns, and credits among the financial information that may be relevant. Review the official 2026 Selling Guide with the buyer's lender and local professionals. A seller should not assume that every requested credit will be permitted or have a dollar-for-dollar effect on value.

6. Map every contingency, deadline, and deposit

A contingency can give a party time to investigate, obtain approval, negotiate, or terminate under stated conditions. Common categories involve inspection, financing, appraisal, title, attorney review, association documents, insurance, property sale, and final walkthrough. Names and effects vary. Fannie Mae's home-selling process overview notes that contingencies often benefit buyers and can permit exit when an inspection or appraisal condition is not satisfied. Only the actual contract and local law define the result.

Build a deadline map with the event, responsible party, required notice or document, delivery method, cure period if any, and consequence. A short inspection period is not automatically strong if access cannot be scheduled or the contract permits a broad exit. A large deposit is not automatically nonrefundable. Record when it is due, who holds it, what happens during each contingency, and what the seller may lawfully receive after default.

Scenario: Priya Shah examines a “no inspection” offer. Priya's buyer checks a box described in the email as waiving inspection, but an attached addendum allows termination after a five-day property review. Priya and her attorney use the signed language, not the email label. The observed fact is a five-day review right. Priya can compare it with another offer's inspection cap and repair-request limit only after the local professional explains both clauses.

7. Compare the whole timeline, including possession

Put every date on one line from offer expiration through possession. Include acceptance, deposit delivery, attorney review, disclosures, inspection, appraisal order and completion, financing application, commitment, title work, final walkthrough, closing, recording, funds availability, key transfer, and any seller or buyer occupancy. Ask which dates are fixed, target dates, or dependent on another event.

A fast proposed closing can be weak if the lender, attorney, title company, or public records cannot support it. A longer closing can still be the better decision when the estimated net is higher and the dependencies are credible. Compare timing with the project's insurance, loan maturity, rate or extension terms, utilities, security, landscaping, weather, and planned cash use. The house flip insurance guide explains why coverage should follow the property's actual construction, vacancy, listing, contract, and occupancy status through closing.

Possession deserves its own line. Closing, recording, funding, and key delivery may not be simultaneous. Early buyer access and post-closing seller occupancy can create insurance, damage, utility, security, and legal questions. Do not solve those issues with an informal text message. Route the written term through the attorney, insurer, and other local professionals before acceptance.

8. Use consistent, lawful criteria for every buyer

Choose among offers using documented transaction terms and lawful seller priorities, not protected characteristics or proxies. HUD states that the Fair Housing Act protects people in housing-related activities because of race, color, national origin, religion, sex, familial status, and disability. State and local law may protect additional classes. The Act also reaches discriminatory terms and conditions of sale.

Use the same comparison fields for all offers. Avoid letters, photographs, social profiles, names, family stories, neighborhood “fit,” or other information that is irrelevant to price, terms, and lawful execution. Ask the listing broker how buyer communications and personal letters are handled under current local policy. Record why the selected contract fit the seller's stated financial, timing, and risk priorities without creating a ranking formula that disguises an unlawful preference.

9. Counter carefully, accept once, and document backups

Decide the seller's priorities before negotiating: minimum estimated net, acceptable closing range, credit cap, deposit expectations, contingency limits, possession, included property, and evidence still needed. A counteroffer can change price or terms, but it can also replace or end an earlier proposal under local contract rules. Do not assume an original offer remains available after a counter. Track expiration times and obtain legal guidance before sending competing counters.

Before acceptance, confirm that the complete contract and all addenda match the selected terms. Capture signatures, dates, delivery, deposits, and the first operational deadlines. A backup offer can preserve an alternative only when it is a valid local agreement with clear activation, notice, withdrawal, deposit, and status terms. Do not interfere with the primary contract or promise a backup buyer that they will receive the property.

Closing communication also needs a verification rule. CFPB warns that scammers may send last-minute false wiring instructions while impersonating real-estate, settlement, or legal professionals. Review its current mortgage closing scam guidance and agree in advance how parties will verify money-transfer instructions through independently confirmed contact information. An offer score cannot offset weak closing security.

Scenario: Andre Williams keeps a real backup. Andre accepts a financed offer after his attorney reviews the contract. A second buyer wants to “stay in line” by text. Andre does not treat that message as a backup. His agent and attorney prepare the locally appropriate written agreement with activation and withdrawal terms. Andre tracks the primary buyer's deposit and financing deadlines without sharing confidential terms or pressuring either buyer outside the approved process.

10. Worked example: Naomi Carter compares three offers on 28 Maple Street

Naomi Carter renovated a 1958 three-bedroom house and listed it after completing the punch-list and closeout workflow. Her licensed agent receives three offers. Naomi keeps the original contracts, has her attorney explain the local terms, and uses one planning sheet for all three. The example below is educational arithmetic, not a recommendation.

Observed written terms:

Shared planning assumptions:

• Sale and settlement allowance before buyer credits: 5.5 percent of price, subject to actual agreements and local charges.
• Debt payoff at day 21: $271,000.
• Additional payoff interest and other carrying costs: $156 per day after day 21.
• Taxes are excluded and will be reviewed with a qualified tax professional.

Calculations:

• Offer A: $545,000 minus $29,975 allowance minus $12,000 credit minus $271,000 payoff minus $3,744 timing cost equals $228,281 estimated cash before taxes.
• Offer B: $538,000 minus $29,590 allowance minus $3,000 credit minus $271,000 payoff minus $1,404 timing cost equals $233,006 estimated cash before taxes.
• Offer C: $532,000 minus $29,260 allowance minus $271,000 payoff equals $231,740 estimated cash before taxes.

Opinions and decision. Offer B has the highest planning net, stronger documented down payment than A, a defined appraisal-gap amount, and a shorter review and closing schedule. Offer C has a slightly lower planning net but no mortgage or lender appraisal dependency. Offer A has the highest price yet the lowest calculated net and the broadest documented dependencies. Naomi does not convert those observations into a promise that B will close. After professional review, she selects B because it fits her documented net, timing, and risk priorities, and she negotiates a formal backup with C.

Naomi keeps three separate views: original contract facts, the planning math, and the team's decision notes. If a deposit is late, the appraisal changes, or a contingency is exercised, she updates the observed facts and follows the local professional's process. She never edits the earlier comparison to make the original choice look more certain than it was.

11. A repeatable Rehabfolio offer-comparison workflow

1. Preserve every offer. Save the original contract, addenda, evidence, delivery time, expiration, and communication record.
2. Normalize the terms. Use the same fields for price, credits, funds, deposits, contingencies, dates, possession, and property.
3. Verify through the right person. Route financing, funds, contract, title, settlement, insurance, appraisal, and tax questions appropriately.
4. Calculate comparable nets. Use the same cost method and date-sensitive carrying assumptions for every offer.
5. Map execution risk. Put every contingency, deadline, document, owner, notice, and consequence on one timeline.
6. Record lawful priorities. State the seller's financial, timing, possession, and risk goals before selecting a buyer.
7. Approve the final agreement. Check that signatures, addenda, dates, credits, items, and negotiated changes match the decision.
8. Run contract operations. Track deposits, inspections, appraisal, financing, title, closing security, backup status, and handoff without erasing history.

Rehabfolio can organize offer files, comparison notes, calculated scenarios, deadlines, contacts, risks, property evidence, expenses, and reports in one project. The reports and collaboration overview shows how teams can share a current record without turning a software status into a legal or lending conclusion. If selling no longer produces an acceptable result, revisit the sell, rent, or refinance guide using current facts rather than the original acquisition assumptions.

A useful comparison does not pretend to predict the buyer. It makes the proposed exchange visible, prices what can reasonably be priced, identifies what remains conditional, and gives the seller and licensed professionals a clean record for the next decision.

Frequently asked questions

Editorial methodology, limitations, and sources

The Rehabfolio editorial team reviewed current federal fair-housing guidance, CFPB mortgage preapproval, seller-closing-disclosure, and closing-security materials, Fannie Mae appraisal and selling guidance, current multiple-offer consumer guidance, and the December 2025 federal tax basis publication cited near the relevant claims. We mapped those sources to first-hand Rehabfolio product workflows for property evidence, offers, financing, expenses, files, contacts, tasks, risks, collaboration, and reports.

Maya Chen, Luis Ortega, Priya Shah, Andre Williams, Naomi Carter, and 28 Maple Street are educational composite scenarios, not customers, testimonials, or performance claims. The dollar examples demonstrate disclosed arithmetic only. They omit taxes and use assumed costs and dates that may not apply to another sale. We did not verify a buyer, interpret a local contract, inspect title, obtain an appraisal, provide a settlement statement, or test a real transaction for this article.

This article owns seller-side comparison from written offers through acceptance, countering, rejection, and backup planning. Existing Rehabfolio guides separately cover acquisition offer math, pre-listing readiness, hard-money borrowing, holding costs, insurance, construction closeout, and exit-strategy selection. We revisit this guide when cited national sources or the product workflow materially changes. Local professionals must supply the current forms, contract meaning, deadlines, charges, compliance duties, and advice for a real property.
