What is ARV in real estate?
After Repair Value, or ARV, is the projected market value of a property once all planned renovations and improvements are complete. It is not the current asking price, the tax assessment, or a rough guess. ARV is a forward-looking number built from real comparable sales, and it sits at the center of nearly every fix-and-flip decision in the US market.
Here is why it matters so much:
- ARV tells investors the ceiling on what a property can sell for after renovation, which directly sets the maximum they should pay to acquire it.
- Lenders use ARV to cap renovation loan amounts, typically at around 75% of ARV, protecting both sides from negative equity.
- The 70% rule, a widely applied guideline in residential investing, runs entirely on ARV as its starting point.
- ARV is distinct from as-is value. A distressed property worth $90,000 today might carry an ARV of $252,000 after a full rehab. Those are two completely different numbers serving two different purposes.
- Homeowners planning major renovations can use ARV to check whether the cost of improvements will actually be reflected in their sale price.
ARV is a prospective estimate, not a guarantee. Think of it as the best defensible answer to the question: “What will this property sell for once the work is done?”
How to calculate ARV step by step
The most reliable method for calculating after repair value is the sales comparison approach, which compares your target property to recently sold homes in similar condition and location. Here is the full process:
-
Identify comparable properties (comps). Search for homes that sold within the last six months in the same neighborhood. Look for properties with similar square footage, bedroom and bathroom count, lot size, and finished quality. Pull at least three comps, ideally more.
-
Calculate price per square foot for each comp. Divide each comp’s sale price by its square footage. If a 1,500 sq ft home sold for $270,000, its price per square foot is $180.
-
Average the price per square foot across all comps. Add up the per-square-foot figures and divide by the number of comps. This average is your baseline rate.
-
Multiply the average by your property’s square footage. If your property is 1,400 sq ft and the average comp rate is $180/sq ft, your baseline ARV is $252,000.
-
Apply the 70% rule to find your Maximum Allowable Offer (MAO). The standard formula is: MAO = (ARV × 0.70) minus estimated renovation cost. If ARV is $252,000 and renovation costs are $40,000, the MAO is $136,400.
| Step | Action | Example |
|---|---|---|
| Find comps | 3+ sales within 6 months, similar size and finish | Three homes at $175, $180, $185/sq ft |
| Average price/sq ft | Add comp rates, divide by count | ($175 + $180 + $185) ÷ 3 = $180/sq ft |
| Estimate ARV | Average rate × subject property sq ft | $180 × 1,400 sq ft = $252,000 |
| Calculate MAO | (ARV × 0.70) minus renovation cost | ($252,000 × 0.70) minus $40,000 = $136,400 |
Pro Tip: Use only comps that reflect the finished quality you plan to deliver. If you are installing granite counters and hardwood floors, your comps should show the same. Matching a luxury renovation to a basic flip comp will inflate your ARV and wreck your margin.
How ARV drives real estate investment and financing decisions
ARV shapes three major decisions in any real estate investment: what to pay, how much to spend on renovations, and how to finance the deal.
For fix-and-flip investors, ARV sets the ceiling on the purchase price. The 70% rule exists precisely because buying at or above ARV leaves no room for holding costs, unexpected repairs, or a soft market at exit. Buying at 70% of ARV minus renovation costs preserves that buffer.
- ARV guides renovation budgets by showing the maximum value the market will absorb. Spending $80,000 on a kitchen in a neighborhood where comps top out at $200,000 is a losing trade regardless of the quality of the work.
- Lenders rely on ARV to set loan limits. Renovation loans typically cap financing at approximately 75% of projected ARV to prevent borrowers from holding more debt than the property will support after completion.
- ARV also informs the BRRRR strategy (Buy, Rehab, Rent, Refinance, Repeat), where investors use the post-renovation value to pull equity out through a cash-out refinance and redeploy it into the next deal.
- For risk assessment, ARV functions as a stress test. If combined purchase price and renovation costs exceed the ARV, the deal fails before it starts.
Key figure: Borrowing beyond 75% of ARV risks holding more debt than the property’s post-renovation value, which is why lenders treat this threshold as a hard ceiling on renovation loan underwriting.

Common mistakes that distort ARV and cost investors money
The most expensive ARV errors are not math errors. They are judgment errors, and they tend to cluster around a few predictable traps.
- Confusing as-is value with ARV. These are fundamentally different numbers. The as-is value reflects what the property would sell for today, in its current condition. ARV reflects what it will sell for after a specific, planned renovation scope. Treating them as interchangeable leads to overpaying.
- Assuming renovation costs equal value added. Spending $50,000 on a renovation does not automatically add $50,000 to the sale price. Market demand drives actual value increases, and some cosmetic improvements affect marketability more than appraised price. A $30,000 landscaping project in a neighborhood where buyers prioritize square footage may return almost nothing.
- Using comps that do not match your planned finish. Pulling broad, generic comps inflates ARV and creates an unrealistic target. Relying on generic or broad estimates can lead to investment risk that only shows up at closing.
- Treating ARV as a guaranteed sale price. ARV is a ceiling estimate, not a prediction. Markets shift, renovation timelines slip, and buyer preferences change. ARV is one input among others used to estimate risk and profitability, not a contract.
- Skipping an independent appraisal. For loan applications especially, informal ARV calculations rarely satisfy lender requirements. Many lenders require an independent appraisal to confirm ARV before approving renovation financing.
Pro Tip: When in doubt, use the most conservative comp in your set, not the average. A lower ARV that holds up at closing beats an optimistic one that collapses your margin.
What ARV percentages actually mean in practice
When lenders and investors talk about “75% ARV” or “70% ARV,” they are describing a ratio that caps either a loan amount or a purchase price as a percentage of the projected post-renovation value. Understanding these thresholds prevents both overborrowing and overpaying.
The 70% rule is the most common investor threshold. It means the total money going into a deal (purchase price plus renovation costs) should not exceed 70% of ARV. The remaining 30% covers holding costs, closing costs, agent commissions, and profit margin.
| ARV Percentage | Who Uses It | Practical Meaning |
|---|---|---|
| 70% ARV | Fix-and-flip investors | Maximum total deal cost (purchase + renovation) to preserve profit margin |
| A typical renovation lender cap corresponds to a maximum loan amount relative to the projected post-renovation value. | ||
| Some refinance programs specify an upper loan-to-value limit for cash-out refinancing on renovated properties, expressed as a percentage of the ARV. | ||
| Conservative investors use a tighter threshold in uncertain or declining markets, expressed relative to the ARV. |
A property with an ARV of $252,000 triggers a maximum loan of $189,000 at the 75% threshold. At the 70% investor rule, the ceiling on total deal cost (purchase plus renovation) is $176,400. If renovation is estimated at $40,000, the maximum purchase price under the 70% rule drops to $136,400. These percentages are not arbitrary. They exist because real transactions carry costs that eat into the spread between purchase price and sale price faster than most first-time investors expect.
How to find the ARV of your property using available resources
Finding a reliable ARV requires real market data, not automated estimates. Here is how to build one from scratch:
- Start with the MLS. The Multiple Listing Service holds the most accurate sold data available. Search for properties sold within the last six months in your target zip code, filtering by similar square footage, bedroom count, and condition. Market data as recent as the last six months provides the most accurate baseline.
- Use public records as a backup. County assessor and recorder databases show sale prices for all recorded transactions. They lag the MLS by a few weeks but cover off-market sales that the MLS misses.
- Check a property valuation tool for a first screen. An IDX home valuation tool can surface nearby comps quickly, though you should always verify the underlying sales data manually before relying on any automated figure.
- Align comps with your planned finish quality. Pull comps that reflect the renovation you intend to deliver. If you are adding a second bathroom, find comps with the same count. If you are upgrading to stainless appliances and quartz counters, find comps with equivalent finishes.
- Account for local market trends. A rising market may support a slightly higher ARV; a cooling one demands more conservative assumptions. Check median days on market and list-to-sale price ratios for your target area.
- Consult a local real estate agent or appraiser. Agents with active transaction history in your target neighborhood often have comp access and local knowledge that no database captures. For loan applications, a licensed appraiser’s formal opinion carries the most weight.
Pro Tip: Pull your comps from a tight geographic radius, ideally within half a mile in urban areas and one to two miles in suburban ones. Comps from a different school district or across a major road can reflect an entirely different market.
Expert guidance on estimating ARV with confidence
Experienced investors treat ARV as a ceiling, not a target. The number tells you the most the market will pay for the finished product. Everything below that ceiling is where your profit lives.
That last point carries real weight. Wholesalers routinely pass along ARV figures that favor their assignment fee. Accepting a seller’s or wholesaler’s ARV without running your own comp analysis is one of the fastest ways to overpay for a property.
A few practices that separate disciplined ARV estimation from wishful thinking:
- Handpick comps manually, selecting only properties that closely match your planned renovation in size, location, and finished quality. Automated valuation models cast too wide a net.
- Recognize that not all renovations add equal value. Market demand and buyer preferences determine which improvements actually move the needle on ARV. A new roof is necessary but rarely adds dollar-for-dollar value. An updated kitchen in a buyer-preferred neighborhood often does.
- Use ARV as a risk management tool, not a sales pitch. Financial experts view ARV as a way to check whether combined purchase and renovation costs will stay below future market value, not to justify a deal you already want to do.
Pro Tip: For any deal involving renovation financing, get an independent appraisal before you close. Lenders require it, and it protects you from building a renovation budget around an ARV that a licensed appraiser will not support.
Understanding how buyers factor repair requests into their offers also helps sellers and investors calibrate renovation scope to what the market actually rewards.
