The complete deal analysis framework — how to find ARV, estimate repairs, calculate your Maximum Allowable Offer, and make offers that are profitable every time.
The After Repair Value (ARV) is the single most important number in wholesaling. Everything else — your repair estimate, your wholesale fee, your offer price — is calculated relative to the ARV. Get the ARV right and the rest of the math is straightforward. Get it wrong and you will either overpay for the contract or bring your cash buyer a deal they cannot profit from.
ARV is what the property will be worth once it has been fully renovated and is ready to sell to a retail buyer. You are not valuing the property as it sits today — you are projecting what a renovated version of it will sell for in the current market. Ryan Zodi of RealEstateSkills.com puts it precisely: ARV is the most probable price a fully renovated version of this property would bring if freely offered on the open market with both a willing buyer and a willing seller.
You find ARV by running comparable sales — properties similar to yours that have recently sold in renovated condition in the same area. These are called comps. The art of running comps is finding properties that are as similar as possible to your subject property, so that the sold price of the comp gives you a reliable estimate of what your property will sell for once fixed up.
Real estate appraisers use a rigorous set of criteria to identify truly comparable properties. Ryan Zodi — who has studied dozens of appraisals across properties he has purchased — distills these into eight rules that every wholesaler should apply.
Stay within a half-mile radius of the subject property. Never cross major roads, highways, or train tracks — these are neighborhood dividing lines. A property on a busy main road values differently from one on a quiet side street.
Start with comps from the last 90 days. Extend to 6 months if needed. Go to 12 months only as a last resort. A 6-month-old comp today may be a year old by the time your cash buyer finishes renovating and resells.
Stay within plus or minus 20% of your subject property's square footage. If your property is 1,200 sqft, look for comps between 960 and 1,440 sqft. Square footage is the most important size variable — it drives price more than bed/bath count.
Try to match exactly. If you cannot find exact matches, get as close as possible and adjust your value estimate accordingly — an extra bedroom typically adds $5,000–$15,000 of value depending on the market.
Single family to single family only. Never use a condo as a comp for a detached home. Never use a mobile home as a comp for a stick-built house. Apples to apples always.
Brick, wood frame, concrete block — these value differently. In Florida especially, concrete block homes value higher than wood frame in the same area due to hurricane resistance. Match construction type when possible.
Stay within 10 years of your subject property's build year. Do not use a 2005 construction as a comp for a 1965 fixer-upper — building codes, materials, and buyer expectations are completely different.
For ARV comps, you want renovated properties that have been fixed up and resold — these are called as-improved comps. A comp that sold as a distressed cash sale is an as-is comp, not an ARV comp. Know the difference and use the right one for your purpose.
The MLS is the gold standard — it has the most data, the most detail, and the most accurate sold prices. If you have investor-friendly agent access, use the MLS first. For everyone else, Redfin.com is the best free alternative — Ryan Zodi considers it his go-to for quick comp pulls in any market across the country. Zillow and Realtor.com also work. PropStream and Property Radar are paid options that give you MLS-level data and additional distressed property filters.
Zillow's Zestimate, Redfin's estimate, PropStream's AVM — these automated valuations can be wildly inaccurate, especially on distressed properties in neighborhoods with few recent sales. Use them as a rough starting point if nothing else is available, but never make a purchase decision based on an automated valuation. Run your own comps every time, on every deal, no exceptions.
Zach Ginn's most important warning about running comps: avoid the "positive mindset" trap. New wholesalers lock up a property and then unconsciously cherry-pick high comps to justify the price they already paid. Cash buyers deal in facts — they will reject deals where the ARV is stretched. Always ask yourself: am I choosing this comp because it is the most accurate comparable, or because it makes my deal look better? If it is the latter, start over with the facts only.
The second input in your offer calculation is the repair estimate. You do not need to be a contractor — and you do not need a perfect number. Alex Martinez's standard is getting within $3,000–$5,000 of the true repair cost. That level of accuracy is achievable without a formal quote, and it is close enough to make confident offers on most deals.
The only person who knows the exact repair cost on a property is the general contractor who will actually do the work — and even they build in a contingency. Your job as a wholesaler is to get a reasonable estimate quickly so you can calculate an offer price and move. You will refine your repair estimation skills over time by getting feedback from cash buyers on the deals you bring them.
The fastest and most practical repair estimation method for beginners is the cost-per-square-foot approach. Alex Martinez uses this on every deal:
Paint, carpet/flooring, minor landscaping. Property is structurally sound, systems functional. Needs freshening up — not renovation.
New flooring throughout, paint interior/exterior, kitchen remodel, bathroom remodel, landscaping. The most common wholesale deal type.
New roof, HVAC, plumbing, electrical, plus full cosmetic. Properties with major structural or systems issues. Requires experienced cash buyers.
For a 1,200 sqft house needing a standard cosmetic rehab: 1,200 × $30 = $36,000 repair estimate. That is your starting number. Adjust up if you saw foundation cracks, a failing roof, or outdated electrical on your walkthrough. Adjust down if the kitchen was recently updated or the roof is newer.
Alex Martinez identifies two repair categories that dramatically change your estimate and must always be explicitly noted when they apply:
New roof: adds $8,000–$15,000 depending on size and material. If the property needs a new roof, add this on top of your per-square-foot estimate — it is not included in the cosmetic calculation.
Foundation / crack slab: can range from $5,000 for minor crack repair to $30,000+ for serious structural work. If you see foundation issues on a walkthrough, flag them immediately with your cash buyer before committing to an offer. This is the one repair category where the cost can blow up a deal entirely.
Alex Martinez's advice for new wholesalers: when you get your first deals under contract and send them to cash buyers, ask them how they estimate repairs. Ask what dollar-per-square-foot number they use in your specific market. Every market is different — Tampa's labor costs are not the same as Cleveland's. Once you know your buyers' repair criteria, you can calculate repair costs exactly the way they do, which means your MAO will be calibrated to what they will actually pay. This is how you stop bringing deals that fall apart at the last minute over repair disagreements.
The Maximum Allowable Offer (MAO) is the highest price you can pay for a property and still leave room for your wholesale fee and your cash buyer's profit. Every offer you make as a wholesaler should be at or below your MAO. Offering above your MAO means either you make no fee, your buyer makes no profit, or both. Offering well below your MAO means more room for negotiation and a more attractive deal for your buyer.
The buyer's percentage — typically between 70% and 80% of ARV — represents the maximum all-in cost a fix-and-flipper wants to have in the property. "All-in" means purchase price plus renovation plus closing costs plus holding costs. They want to be at or below this percentage so they have enough margin to make a profit when they sell.
Why 75%? Because 75% of ARV is the standard refinance threshold — if a flipper wants to do a cash-out refinance after renovating and hold the property as a rental, they need to be 75% all-in to pull all their money back out. In highly competitive markets like Tampa or Atlanta, cash buyers may push to 80% or even 82% because competition for deals drives prices up. In slower or rural markets, buyers may demand 65–70%. Know your market's standard — your cash buyers will tell you.
| Market Type | Typical Buyer % | Implication for Your MAO |
|---|---|---|
| Rural / slow market | 65–70% of ARV | Tighter spread — need deeper discount from seller |
| Standard suburban market | 70–75% of ARV | Standard range — most deals underwritten here |
| Hot / competitive market | 75–80%+ of ARV | More room to pay — easier to get offers accepted |
Notice the $30,000 swing between the 70% and 80% calculations. This is why knowing your cash buyers' actual buying criteria matters so much. If you underwrite to 70% but your buyers actually pay 80%, you are leaving $30,000 of potential deal opportunity on the table — or walking away from deals you could have closed.

Speed is a competitive advantage in wholesaling. The wholesaler who analyzes a deal in 20 minutes and calls the agent back with a firm offer same-day wins over the wholesaler who spends three days "doing due diligence." Your goal is to get accurate enough, fast — not perfect, slow. Alex Martinez's target is 30 minutes from discovery call to offer submission. Build the habit of moving quickly, and your close rate on competitive deals will be significantly higher than wholesalers who overthink.
When you submit an offer, the price is only one element. Alex Martinez identifies the standard terms that make a wholesale offer competitive:
Closing date: 14 days. Motivated sellers want to close fast. A 14-day close — compared to the 30–45 days a financed buyer needs — is a significant advantage. It gives you urgency, reduces the seller's carrying costs, and signals that you are a serious buyer who can actually perform.
Inspection contingency: 7 days minimum. This is your backout clause. It gives you the right to terminate the contract during the inspection period for any reason and get your earnest money back. As a wholesaler, the inspection period is your window to find and assign the contract to your cash buyer. Never submit an offer without an inspection contingency — it is your primary protection if you cannot find a buyer in time.
Earnest money deposit: $500–$2,500 for off-market deals. On MLS deals, 1% of the purchase price is the standard. If you have a cash buyer lined up already, they can fund the EMD on your behalf — meaning you put zero dollars into the deal out of pocket.
Cash offer — no financing contingency. This is the biggest seller benefit of working with a wholesaler. Traditional buyers need 30–45 days for financing approval with risk of falling through. Your offer has no financing contingency — it is cash, it is certain, and it closes in two weeks. Lead with this in every offer conversation.
"Speed is part of the name of the game. We're not trying to be perfect and take days to analyze a property because good deals go quickly. Get the ARV. Get the repairs number. Submit your offer. You can always refine — but you can't get back a deal that went to someone else while you were still analyzing."
It happens — especially early on. You get excited about a deal, submit an offer, and the seller accepts at a price where your numbers are tighter than you would like. You have two tools available before you panic. First, use your inspection period to get your cash buyers into the property. Their feedback on repairs and their willingness to pay will tell you immediately whether the deal works. Second, if a cash buyer identifies legitimate defects you were not aware of when you made the offer, use those findings to renegotiate the purchase price with the seller. Your inspection contingency protects you — and a legitimate renegotiation based on discovered defects is standard industry practice.
The wholesalers who make the most money are not the ones who spend the most time analyzing deals. They are the ones who built the habit of analyzing deals quickly and consistently — good enough to make real offers, fast enough to be first. Run comps on every property you find, even ones you do not pursue. Calculate the MAO. Submit your offer. The first ten times feel slow. By the fiftieth time, you will do it in twenty minutes without thinking. That fluency is worth more than any spreadsheet tool anyone will ever sell you.
5 questions — click your answer, then check all at once.
1. You are running comps on a 3/2, 1,100 sqft property built in 1968 in a suburban Tampa neighborhood. You find a comp that sold 4 months ago for $320,000 — but it is a 3/2 at 1,650 sqft, built in 2004, located across a major highway. Should you use this comp? Why or why not?
2. A property is 1,400 sqft and needs full cosmetic renovation — new flooring, paint, kitchen, bathrooms, exterior, and landscaping. Using the cost-per-square-foot framework, what is the estimated repair cost — and what would you add if the property also has a failing roof?
3. Using the MAO formula: ARV = $280,000, repairs = $40,000, wholesale fee = $10,000, buyer's percentage = 75%. What is your MAO — and what would happen to your MAO if your cash buyer operates at 80% instead of 75%?
4. You submit an offer and the seller accepts. During the inspection period, your cash buyers walk the property and tell you the repair cost is actually $55,000 — not the $35,000 you estimated when you made the offer. The higher repair cost means your buyer cannot make a profit at the contracted price. What are your two options — and which is preferable?
5. Why does Alex Martinez target a 14-day closing date rather than 30 days on wholesale offers — and how does the inspection contingency work as a safety valve within that 14-day timeline?
