The Real Estate Analysis Problem
There are two common traps in deal analysis. The first trap is analysis paralysis — spending so much time running numbers that deals expire before an offer is made. The second trap is no analysis at all — making offers based on gut feel and a quick online estimate, then discovering the numbers do not work after the contract is signed.
Neither approach builds a portfolio. What does is a repeatable underwriting framework that produces accurate numbers fast — consistently enough that you can analyze every lead that comes through your pipeline without sacrificing speed or accuracy.
This is that framework.
Step 1 — Build the Property Profile
Before you run a single number, you need basic property facts. These take two minutes to pull and determine which analysis path you follow.
- Property type: Single family, multifamily, condo, townhouse
- Square footage and bed/bath count
- Year built
- Current condition: Cosmetic, moderate rehab, full gut, or tear-down
- Current occupancy: Vacant, owner-occupied, tenant-occupied
- Asking price or seller's number
These facts determine your comp search parameters, your repair estimate approach, and which exit strategies are viable on this property.
Step 2 — Establish ARV
ARV — After Repair Value — is the foundation of every real estate deal analysis. Every other number in your underwriting depends on getting this right.
Pull comparable sales meeting all of these criteria:
- Sold within the last 90 days
- Within 0.5 miles in urban and suburban markets, 1 mile in rural markets
- Same property type
- Within 20% of subject property square footage
- Similar bed and bath count
- Similar condition post-renovation
Use 3 to 5 comps minimum. Adjust for meaningful differences — an extra bathroom adds value, a busy road reduces it. Your ARV is a defensible number that an appraiser would support, not the highest comp you can find.
If you cannot find comps that meet these criteria, the market is telling you something. Thin comp data means higher risk — price accordingly.
Step 3 — Estimate Repairs
Repair estimation is where a deal analysis often breaks down. A drive-by is not a repair estimate. A quick walk-through without a line-item breakdown is not a repair estimate. A real repair estimate covers every system and surface in the property.
Repair Categories to Assess
- Roof: Age, condition, remaining life, repair vs replace
- HVAC: Age, condition, repair vs replace
- Plumbing: Supply lines, drain lines, water heater, fixtures
- Electrical: Panel age and capacity, wiring condition, outlets
- Foundation: Cracks, settlement, drainage issues
- Kitchen: Cabinets, countertops, appliances, flooring
- Bathrooms: Fixtures, tile, vanities, water damage
- Flooring: Type, condition, repair vs replace throughout
- Paint: Interior and exterior
- Windows and doors: Condition, efficiency, security
- Exterior: Siding, gutters, landscaping, driveway
Add a contingency to your line-item total; many investors use 10 to 15%, so set the figure your own experience supports. Hidden damage is common once walls open up.
Step 4 — Select Your Exit Strategy
Not every property works for every exit strategy. Your ARV, repair estimate, and property profile determine which exits are viable.
- Wholesale: Works when repairs are heavy and your MAO leaves enough spread for an end buyer. Best for properties whose repair scope puts off retail buyers.
- Fix and flip: Works when ARV supports the profit margin you require after all costs. Best in strong resale markets with short days on market.
- Buy and hold: Works when market rent produces the cash-on-cash return you require at your purchase price and financing terms.
- BRRRR: Works when a refinance on the ARV at your lender's LTV covers your total cash invested; 75% is a common planning assumption, so confirm yours. Best for properties that will appraise well post-renovation.
- Subject-to: Works when the seller has a low existing rate and PITI sits far enough below market rent to cover your operating expenses, a capital reserve and the cash flow you require.
- Seller finance: Works when the seller owns free and clear and below-market rate terms produce positive cash flow.
- Lease option: Works when there is a tenant-buyer market and enough spread between your terms and market rent.
- Novation: Works when the seller wants retail but the property needs work and post-repair ARV produces enough margin.
Avoid pre-selecting an exit strategy before you analyze the deal. Run all exits and let the numbers show which strategy produces the best return on this specific property.
Step 5 — Calculate MAO for Your Target Exit
Once you know your ARV, repair estimate, and target exit strategy, calculate your Maximum Allowable Offer. This is the ceiling above which you do not buy.
MAO formulas by exit:
- Wholesale MAO: (ARV x 65-70%) minus Repairs minus Assignment Fee, with 65-70% as a common rule-of-thumb range; confirm yours
- Fix and Flip MAO: ARV minus Repairs minus Holding Costs minus Closing Costs minus Financing Costs minus Desired Profit
- BRRRR MAO: (ARV x 75%) minus Rehab minus Closing Costs minus Holding Costs, with 75% standing in for your lender's refinance LTV; confirm yours
- Buy and Hold MAO: Derived from target cash-on-cash return and available financing terms
Step 6 — Make the Offer
Start your offer below MAO. That leaves room to negotiate while staying below your ceiling. If the seller counters above MAO, you walk. The math does not change because a seller is motivated or because you like the property.
Speed matters. A well-analyzed offer made the same day beats a perfectly analyzed offer made three days later. Build your analysis process fast enough that you can move quickly on every lead.
Common Underwriting Errors
- Using an online estimate for ARV: automated estimates are not comps. They are algorithms. Use actual MLS sales data.
- Ignoring days on market: A comp that sat on the market far longer than its neighbors before selling is a weaker ARV indicator. Filter for properties that sold within normal market timeframes.
- Estimating repairs without a walkthrough: Desktop repair estimates are guesses. Walk the property or have a contractor walk it before committing to a number.
- Forgetting sell-side closing costs: On a fix and flip, agent commissions and closing costs at sale are best estimated line by line, not as a flat percentage of ARV. Forgetting this number alone can wipe out an entire projected profit.
- Analyzing only one exit: The best exit on a given property is not always obvious before you run the numbers. Model multiple exits before deciding.
How Appraize Automates This Framework
Appraize runs this entire six-step framework automatically. Enter a property address and get ARV from real MLS comps, line-item repair estimates calibrated to your local market costs, and MAO calculations for all 8 exit strategies simultaneously — in under 30 seconds.
The analysis that used to take hours of manual research, spreadsheet work, and comp pulling happens automatically. You review the numbers, make your decision, and move to the next deal.
Run a complete deal analysis at Appraize. ARV, repairs, and all 8 exit strategies in under 30 seconds.
The Bottom Line
Real estate deal analysis is not complicated. It is a six-step process: build the property profile, establish ARV, estimate repairs, identify viable exits, calculate MAO, and make the offer. Closing more deals is less about being smarter than about running this process faster and more consistently.
Build the framework. Run it on every lead. Never make an offer without it. Applied consistently, that discipline is what turns a busy deal pipeline into a growing portfolio.
