ARV Meaning in Real Estate: After Repair Value Explained
After Repair Value — or ARV — is arguably the most important number in any fix-and-flip or wholesale deal. It's the estimated market value of a property after all renovations and repairs are completed. Get your ARV right, and you'll make money. Get it wrong, and you could lose your shirt.
This guide covers everything you need to know about ARV: what it is, how to calculate it accurately, the 70% rule, and the mistakes that trip up new investors.
What Is ARV (After Repair Value)?
ARV is the projected sale price of a property once it has been fully renovated to market standards. It's a forward-looking estimate based on what comparable, fully-updated homes in the same area have recently sold for.
The formula is simple in concept:
ARV = Current Property Value + Value Added by Repairs/Renovations
But in practice, you don't calculate ARV by adding repair costs to the current value. Instead, you determine ARV independently by analyzing comparable sales (comps), and then work backward to figure out your maximum purchase price.
Why ARV Matters
ARV is the foundation of every investment calculation in the fix-and-flip and wholesale space:
- Maximum Allowable Offer (MAO) — your purchase price is derived from ARV minus repairs minus your profit target
- Profit estimation — ARV minus purchase price minus repairs minus holding costs minus selling costs equals your expected profit
- Wholesale assignment fee — wholesalers use ARV to determine what a flipper will pay, which sets the assignment fee
- Lender underwriting — hard money and private lenders use ARV to determine loan-to-value ratios and maximum loan amounts
- Risk assessment — a deal with a high-confidence ARV is fundamentally different from one where the ARV is a guess
How to Calculate ARV: Step-by-Step
Step 1: Define Your Subject Property's "After" Condition
Before you can find comps, you need to know what the property will look like after renovation. A property rehabbed to basic rental condition has a very different ARV than one renovated to high-end retail standards. Define your renovation scope first.
Step 2: Find Comparable Sales (Comps)
This is the heart of ARV analysis. You're looking for properties that match what your subject will be after repairs. The ideal comp is:
- Within 0.5 miles of your subject (up to 1 mile if needed, same neighborhood or subdivision preferred)
- Sold within the last 6 months (up to 12 months in slow markets)
- Similar size — within 200 square feet and same bedroom/bathroom count
- Similar condition — fully renovated, not distressed or wholesale sales
- Same property type — single-family to single-family, not mixed types
- Similar lot size and features — pool, garage, corner lot, waterfront
Step 3: Adjust for Differences
No comp is perfect. You need to make adjustments for meaningful differences between each comp and your subject property:
- Square footage — calculate the price per square foot of each comp and adjust. If your subject is 1,800 sq ft and the comp is 2,000 sq ft at $300,000, the per-sq-ft value is $150. Your subject's adjusted value would be $270,000.
- Bedrooms/bathrooms — adding or removing a bedroom typically affects value by $10,000-$25,000 depending on the market
- Garage — a 2-car garage vs. no garage can represent $15,000-$30,000 in value
- Lot size — significant differences in lot size warrant adjustment
- Age and condition — a 2020 build comp vs. your 1985 subject (even after rehab) may need adjustment for structural age
- Location quality — even within 0.5 miles, differences in street quality, noise, or school zones matter
Step 4: Select Your Best 3-5 Comps
From all available sales, narrow to 3-5 comps that are the best match to your subject property's post-renovation condition. More is not always better — five strong comps beat twenty mediocre ones. Weight more recent sales and closer proximity higher.
Step 5: Calculate Your ARV
Take the adjusted values of your best comps and determine your ARV. Most investors use one of these methods:
- Simple average — add up the adjusted comp values and divide by the number of comps. Works when comps are tightly clustered.
- Weighted average — give more weight to the closest, most recent, and most similar comps. This is more accurate when comp quality varies.
- Median — use the middle value to avoid being skewed by outliers
- Conservative approach — use the lower end of the range. If your comps suggest $280,000-$310,000, use $285,000 as your ARV. This protects your downside.
The 70% Rule
The 70% rule is the most widely used formula for determining your maximum offer price on a flip:
Maximum Offer = (ARV x 70%) - Repair Costs
Example
- ARV: $300,000
- Estimated repairs: $45,000
- Maximum offer: ($300,000 x 0.70) - $45,000 = $165,000
The 30% margin is designed to cover your holding costs (mortgage, utilities, insurance, taxes), selling costs (agent commissions, closing costs), and profit. In reality, the percentage varies by market and deal:
- Hot markets with fast sales — some investors work on 75-80% because holding costs are minimal
- Slow markets or expensive properties — you may need 65% to account for longer holding periods
- Wholesalers — typically use 65-70% to leave room for the end buyer's profit
Where to Find Comp Data
- MLS (Multiple Listing Service) — the gold standard for comp data. Access through an agent or investor-friendly MLS tools.
- County assessor records — public sale records are free but lack property condition details
- Real estate data platforms — tools like Deal Run's comp analysis pull MLS and public record data together with filtering, mapping, and adjustment tools
- Zillow/Redfin sold data — free but limited in accuracy and filtering compared to MLS data
- Appraisals — hiring an appraiser ($300-$500) gives you a licensed professional opinion, useful for high-value deals
Common ARV Mistakes
1. Using Active Listings as Comps
Active listings are asking prices, not sold prices. A property listed at $350,000 might sell at $320,000 or not at all. Only use closed/sold transactions for ARV calculations.
2. Cherry-Picking High Comps
It's tempting to use only the highest-priced comps to justify a deal. This is how investors lose money. Always include the full range of comparable sales and lean toward conservative estimates.
3. Ignoring the Market Direction
Comps tell you where the market was, not where it's going. If rates are rising and sales are slowing, your ARV should reflect a potentially softer market at the time you'll sell (3-6 months from now).
4. Comparing Distressed Sales to Retail
Foreclosure sales, short sales, and investor-to-investor wholesale transactions sell below market value. Don't mix these with retail sales in your comp set — use them for estimating purchase price, not ARV.
5. Overestimating Renovation Impact
Not all renovations add dollar-for-dollar value. A $50,000 kitchen remodel in a $200,000 neighborhood won't return $50,000 in added value. Your ARV is capped by what the market will pay for the best home in that area.
6. Too Wide a Search Radius
Expanding your comp search to 2+ miles to find "better" numbers often leads to using comps from different neighborhoods with different value drivers. Stay tight — 0.5 miles is ideal, 1 mile is the max for most suburban markets.
ARV for Different Exit Strategies
Your ARV calculation changes depending on what you plan to do with the property:
- Fix and flip — use retail-condition comps (fully renovated, sold to owner-occupants). This is the standard ARV.
- Wholesale — you need to know the ARV so you can back into what a flipper will pay. Use the same retail comps, but your assignment fee comes from the spread between your contract price and the flipper's MAO.
- BRRRR (rental) — your ARV matters for the refinance step. Lenders will appraise the property after renovation, and your loan amount depends on this value. Use the same comp methodology but make sure the property will appraise, not just sell.
- Buy and hold — ARV is less critical for pure rentals because you're not selling. Instead, focus on rent comps (ARR — After Repair Rent) and cash flow analysis.
Using Technology to Calculate ARV
Modern investor tools have made ARV calculation faster and more data-driven. Deal Run's comp analysis feature lets you search for comparable sales around any property, filter by date, condition, and property characteristics, view comps on a map, and calculate your ARV with adjustments — all in one workflow.
While technology speeds up the process, it doesn't replace judgment. Always review the comps yourself, drive the comp properties if possible, and verify that the data matches the physical reality on the ground.
Wrapping Up
ARV is the number that makes or breaks every flip and wholesale deal. Calculate it conservatively using 3-5 strong comps within a tight radius and recent timeframe. Apply the 70% rule (or your market-specific variation) to set your maximum offer. And never let the excitement of a deal tempt you into inflating your ARV to make the numbers work — the market doesn't care what number you need.
