ARV in real estate means after repair value: an estimate of what a property could sell for once a specified renovation is complete. You support it with sales of comparable finished homes. Repair spending, your purchase price and your desired profit are separate inputs.
That separation matters when a lead arrives with a tempting spread. A house offered at $300,000 with a claimed $480,000 ARV has a $180,000 gap on paper. You still have to pay for the work, financing, holding expenses and resale. You also have to prove the $480,000.
This walkthrough takes you from comps to an offer using one fictional project. If you're still assembling properties to analyze, start with the guide to finding distressed properties. Once you have an address, the first job is to describe the home you expect to sell.
ARV, current value and repair spending answer different questions
ARV describes a finished property under stated assumptions. An as-is estimate describes its present condition. Neither tells you what the renovation will require.
| Number | What it describes | How to use it |
|---|---|---|
| As-is value | Estimated market value in the current condition | Compare the asking price with similar unrenovated sales |
| ARV | Estimated value after the planned work | Set a supported resale assumption |
| Repair budget | Expected spending to complete that work | Build from the scope and contractor estimates |
| Assessed value | The jurisdiction's value for property-tax administration | Check property records and the assessment date; do not substitute it for a renovation appraisal |
| Offer ceiling | Maximum purchase price after expenses and your required margin | Calculate from the exit value and the full project budget |
Putting $65,000 into a house does not establish a $65,000 increase in its resale price. Some work corrects a defect buyers expected to be absent already. Other work changes the home's usefulness. The amount buyers recognize has to come from the market.
An appraisal adds another distinction. The Consumer Financial Protection Bureau describes an appraisal as an independent opinion of property value. Your acquisition worksheet is your estimate; a lender may require its own valuation. Neither is a promise that a buyer will pay the projected amount.
How to calculate ARV from comparable sales
A useful ARV formula is:
ARV estimate = a supported reconciliation of comparable sale prices, adjusted for meaningful differences.
For a simple worksheet, you can assign weights to the adjusted values and add them together. The hard part is deciding which properties belong in the comparison and whether the adjustments hold up.
1. Write the finished-property description
Record the property type, size, bedroom and bathroom count, layout, parking, site features and planned finish level. Be specific about which features exist today and which depend on the work getting approved and completed.
For our fictional project, the finished home will be a 1,500-square-foot detached house with three bedrooms, two bathrooms and a standard cosmetic renovation. There is no addition, new dwelling unit or change of use in the plan. The repair estimate is $65,000.
That description keeps the search honest. A renovated four-bedroom house with a permitted addition might be nearby, but it represents a different finished product. A waterfront sale won't become useful because you can draw a small enough search circle around it.
2. Find closed sales that compete with that home
Start with nearby renovated homes that a buyer would reasonably compare with yours. Check the transaction date, condition at sale, size, layout and location. Look at photos and listing descriptions where available; the word “updated” can cover very different work.
Fannie Mae's comparable-sales guidance emphasizes similar physical and legal characteristics and allows competing market areas when they provide the best evidence. Its appraisal framework calls for at least three closed comparables. That is useful discipline for an investor worksheet, though it does not create a universal three-sale rule for every investment decision.
Treat a tight radius or recent-sale filter as a starting search setting. If your search has no good matches, expand it deliberately and explain the compromise. A larger pile of poor matches won't make the estimate stronger.
3. Verify what the sale record actually proves
A recorded price can establish that a transaction occurred. It may tell you much less about the house's interior condition, concessions or the circumstances of the sale.
In King County, the assessor's eSales residential search is one official starting point for sale research. Pair the record with evidence of the property's condition at the time of sale. A recent photo of a renovated house doesn't prove it looked that way when an older transfer closed.
Keep an evidence note beside each comp: source URL, contract or closing date when known, sale price, photos reviewed, and unresolved questions. Flag nominal transfers, unusual financing and transactions involving multiple parcels for further review before treating the recorded amount as a normal one-house sale.
4. Adjust the comps toward the subject
If a comp has a valuable feature the finished subject will lack, you generally adjust that comp downward. If it lacks a feature the subject will have, you may adjust it upward. The adjustment needs support for that market and property type.
Fannie Mae's adjustment guidance calls for market-based adjustments and an explanation of how the final value is reconciled. It does not supply a universal price for another bathroom, a garage stall or an extra square foot.
For an initial acquisition screen, record the difference even if you cannot price it reliably yet. “Comp has a second garage stall; adjustment unresolved” is more useful than silently copying a dollar allowance from an unrelated market. Have an agent or appraiser review the weak spots before relying on the number in an offer.
5. Reconcile a range and date the estimate
Give the best-supported comps the most influence. Write down why you used them, which sales you rejected, and what could move the value lower.
Also state the timing assumption. Today's comparable sales support an estimate under current market evidence; your renovation may finish in a different market. Model that exposure explicitly instead of adding assumed appreciation to rescue the deal.
Worked ARV example: three comps and a $480,000 estimate
Every price, adjustment and weight below is hypothetical. Replace these teaching inputs with researched sales and supported adjustments for an actual property. Assume you have already confirmed that the three homes compete with the planned 1,500-square-foot finished house.
| Fictional comp | Closed price | Illustrative adjustment toward the subject | Adjusted value | Weight |
|---|---|---|---|---|
| A | $490,000 | Subtract $10,000 for a superior feature | $480,000 | 40% |
| B | $460,000 | Add $15,000 for an inferior feature | $475,000 | 40% |
| C | $500,000 | Subtract $15,000 for superior features | $485,000 | 20% |
The weighted calculation is:
($480,000 × 0.40) + ($475,000 × 0.40) + ($485,000 × 0.20) = $479,000.
For this worksheet, round to the nearest $10,000 for a $480,000 base ARV, with the adjusted comp indications spanning $475,000 to $485,000. The weights assume A and B are better matches than C. Real weights need a reason beyond getting the answer you hoped for.
Price per square foot provides a cross-check: $480,000 divided by 1,500 square feet is $320 per square foot. It should not become a blanket rate for every house nearby. Applying that average to a much larger home assumes size adds value at a constant rate, while also overlooking the lot, layout and other differences.
The useful deliverable is the worksheet plus its supporting evidence. “ARV $480k” in a text message gives the next buyer nothing to inspect.
Turn the ARV into a maximum offer
Work backward from expected sale proceeds. Keep the assumptions visible so you can change them when a contractor, lender or buyer gives you better information.
Purchase ceiling = projected resale price − project expenses other than purchase − required profit.
Here is the same fictional project with a full budget. Amounts are illustrative. The assumed selling allowance covers resale transaction expenses; replace it with quotes for the actual transaction.
| Budget line | Hypothetical amount |
|---|---|
| Base resale estimate | $480,000 |
| Selling expenses, assumed at 7% | −$33,600 |
| Renovation scope | −$65,000 |
| Separate repair contingency | −$10,000 |
| Financing and holding expenses | −$20,000 |
| Acquisition closing expenses | −$8,000 |
| Required project profit before income taxes | −$50,000 |
| Calculated purchase ceiling | $293,400 |
Check what each line includes. Your renovation scope might already include permits, design, disposal and tax on contractor work. Your holding estimate should account for the expected ownership period, insurance, property taxes, utilities and financing terms. Add missing items, but don't charge yourself twice for the same expense.
The $293,400 ceiling is only as reliable as that budget. It also assumes the contingency is spent. Getting a roof bid or discovering a title obligation can change the answer without changing ARV at all. A property lien search belongs in due diligence alongside the construction review.
Where the 70% rule fits
The familiar screening calculation is ARV × 70% − repairs. At $480,000 ARV and $65,000 in repairs, it produces $271,000. A wholesaler allowing a hypothetical $15,000 assignment fee would reduce the contract-price screen to $256,000.
Those results differ from the itemized budget because the rule reserves a flat 30% of resale value for expenses and margin. It doesn't know your actual financing, holding period, transaction expenses or profit requirement. Use the screen to decide what deserves closer work, then build the budget.
Don't subtract that entire 30% and then subtract all the same expenses again without understanding the overlap. If you use the itemized buyer ceiling instead, an assignment fee is another acquisition expense: a $15,000 fee would leave $278,400 for the seller's contract price under this example's assumptions. Whether a buyer accepts those assumptions remains an open question.
Stress-test the resale price before making an offer
A small change in ARV can take a large bite out of the amount you can pay. Below, only resale price and its 7% selling-expense allowance change. Repairs, contingency, financing, acquisition expenses and the $50,000 profit target stay fixed.
| Scenario | Resale assumption | Selling expenses | Purchase ceiling |
|---|---|---|---|
| Downside: 5% below base | $456,000 | $31,920 | $271,080 |
| Base worksheet | $480,000 | $33,600 | $293,400 |
| Upside: 5% above base | $504,000 | $35,280 | $315,720 |
These sensitivity cases measure the effect of changing one assumption. A $24,000 decline in resale value cuts the purchase ceiling by $22,320 in this simplified model. At a fixed purchase price, the same change reduces expected profit by $22,320, assuming everything else holds.
Run another case for a repair overrun or longer hold. If the transaction only works when every assumption lands at the favorable end, mark it for more diligence. Raising ARV until the spreadsheet works hides the decision you're actually making.
Code violations help you find a lead; comps support its value
A code violation record can identify work that needs investigation. It cannot tell you that buyers will pay a particular amount for the completed home. The record also may not describe every defect or provide a complete repair scope.
Before giving value to a converted basement, extra bedroom or additional unit, check the permit history and confirm how that space can be used. If the proposed use is uncertain, analyze the existing verified configuration first and put the expansion into a separate scenario. Don't price the upside as though approval has already happened.
Renovation lending makes that scope connection explicit. Fannie Mae's HomeStyle Renovation guidance requires an as-completed appraisal estimating value after the proposed work. That is one lending program's requirement; it does not establish a universal loan amount for an investor's ARV estimate.
In the internal underwriting workflow we use alongside FlaggedLeads, ARV is deliberately supplied from manual comp research. A property's estimated value and Deal Score don't fill that role. The score helps prioritize which records to investigate; the comp packet supports the resale assumption.
You can use the Seattle code violation map to find addresses for that first research pass, then filter the violation list before spending effort on comps. Keep the source date, condition evidence and open questions attached to each property. The next call to an agent or contractor should resolve a named uncertainty.
Frequently asked questions
Is ARV the purchase price plus renovation costs?
No. ARV estimates the finished property's market value. Purchase price and renovation costs describe spending. Buyers may recognize more or less value than the work costs, so use comparable finished-home sales to support the resale estimate.
What does ARV mean in wholesaling?
It is the estimated resale value after the end buyer completes the planned work. A wholesaler uses it as an input to the buyer's acquisition budget. Repairs, transaction expenses, the buyer's required profit and any assignment fee still have to fit. An ARV claim alone does not establish a profitable contract price.
Can I use an online home estimate as ARV?
Use it as a starting reference only after checking what condition and property facts it assumes. It may not describe your planned finished home. Verify the recent sales, size, legal use and renovation scope before treating the estimate as a resale input.
Does a higher ARV mean I can borrow more?
It can affect a lender's valuation analysis, but the lender sets its own eligibility rules, valuation requirements and loan limits. Your estimate may differ from the lender's appraisal. Obtain terms for the actual project before assuming a percentage of ARV will fund the purchase and renovation.
