The Deal Analysis Checklist: What to Verify Before You Make an Offer
Every deal looks good in the listing photos. The kitchen is staged, the description calls it "turnkey" or "great bones," and the asking price feels almost reasonable for the neighborhood. None of that tells you whether the deal actually makes money.
The investors who build real portfolios aren't the ones who move fastest — they're the ones who run the same checklist on every property, every time, before they ever put pen to paper on an offer. Skipping a step doesn't usually blow up the deal you're looking at today. It blows up the one three deals from now, when you're moving fast and assume you already checked something you didn't.
Why It Matters
An offer is a commitment, not a first draft. Once it's accepted, you're in earnest money, inspection timelines, and lender deadlines — all of which cost money and goodwill to unwind if the deal turns out to be wrong.
Analyzing the deal before the offer means you walk into negotiations knowing your number, not guessing at it. It also means when a seller counters, you know immediately whether the new price still works or whether you're better off walking.
The Checklist
1. Confirm the numbers you're using are real, not assumed
- Purchase price — the actual number you'd offer, not the list price
- ARV (after repair value) — based on recent, comparable sales, not the listing agent's optimistic estimate
- Rehab budget — from a contractor walkthrough or a detailed scope, not a per-square-foot guess
- Rental comps — actual rents for similar units nearby, not a number pulled from a rent estimator alone
Every one of these inputs can be wrong in a way that makes a bad deal look good. Verify each one independently before trusting the output.
2. Run the numbers for your actual strategy
A flip, a long-term rental, and a BRRRR are three different math problems with the same property. Know which one you're underwriting before you calculate anything:
- Flip — ARV minus purchase, rehab, holding costs, closing costs, and selling costs
- Buy-and-hold (LTR/STR) — monthly cash flow after all expenses and debt service, plus cash-on-cash ROI
- BRRRR — whether the refinance appraisal will support pulling your capital back out, and what the deal looks like if it doesn't
3. Stress-test the timeline
Add a buffer to whatever timeline you're handed. Rehab schedules slip, financing takes longer than promised, and properties sit on the market longer than the comps suggest. Recalculate the deal assuming the realistic timeline, not the best-case one, and check whether it still clears your target return.
4. Check financing terms against the actual deal
Down payment, interest rate, loan term, and points all move your cash-required and cash flow numbers meaningfully. Confirm these against what a lender has actually quoted you for this type of property, not a generic assumption carried over from the last deal.
5. Verify holding costs are in the model
Mortgage or loan interest, taxes, insurance, and utilities accrue every day the property isn't producing income. If holding costs aren't in your total project cost, your margin is thinner than the spreadsheet says.
6. Confirm the exit is realistic
For a flip: is there actual buyer demand at your target ARV in this specific neighborhood, right now? For a rental: is the rent you're underwriting actually achievable, or is it the highest comp in the set? Anchor to the median, not the best case.
7. Compare against your target return
Every deal should be measured against a number you set in advance — target cash-on-cash ROI, target flip profit, or target return on equity. If the deal doesn't clear that bar after steps 1–6, the answer is no, regardless of how good the property looks.
Common Mistakes
- Trusting the listing agent's rehab estimate instead of getting your own contractor walkthrough
- Using best-case comps to justify a purchase price that only works if everything goes right
- Skipping the financing check and assuming last deal's rate and terms still apply
- Leaving holding costs out entirely, which quietly erodes the margin on every deal
- Analyzing the deal after the offer is already in, which turns due diligence into damage control instead of decision-making
How ProfitTrackr Helps
Running this checklist by hand across multiple prospects — each with its own purchase price, rehab budget, financing terms, and holding cost assumptions — is exactly the kind of work that gets skipped when you're moving fast. ProfitTrackr's Prospects and Compare views let you log every input for a property once, then see flip profit, cash-on-cash ROI, and Investment Score calculated automatically, with the positives and concerns flagged for you.
Because your default underwriting assumptions — down payment, interest rate, closing costs, contingency — are saved in Settings, every new prospect starts from numbers you've already validated instead of numbers you're re-guessing under time pressure. When a deal comes in below your target return, you'll see it before you write the offer, not after you're under contract.
Key Takeaways
- A deal analysis checklist exists to catch a bad deal before you're financially committed to it, not after
- Verify purchase price, ARV, rehab budget, and rental comps independently — don't trust a single source for any of them
- Match your math to your strategy: flip, buy-and-hold, and BRRRR each require different calculations
- Build a timeline buffer and holding costs into every projection, not just the ones that already look tight
- Measure every deal against a target return you set in advance, and be willing to walk when it doesn't clear the bar
