When a real estate investor looks at a distressed property, one of the first questions is: "What will this property be worth after repairs?"
That number is known as After Repair Value (ARV).
ARV is one of the most important numbers in house flipping, wholesaling, and other real estate investment strategies. It helps investors estimate a property's potential value after renovations, determine how much they can afford to pay, evaluate potential profit, and decide whether a deal is worth pursuing.
But calculating ARV isn't as simple as finding three nearby houses and averaging their sale prices.
A reliable ARV requires carefully selected comparable properties, adjustments for differences between properties, realistic assumptions about the finished condition, and an understanding of the local real estate market.
In this guide, you'll learn:
ARV stands for After Repair Value.
It is the estimated market value of a property after the planned repairs and renovations have been completed.
In other words, ARV answers the question:
"How much could this property reasonably be worth once it has been renovated to the target condition?"
For example, suppose you find a distressed property that currently needs a new kitchen, flooring, paint, bathroom upgrades, and exterior improvements.
The property may currently be worth $200,000 in its existing condition.
After completing the renovations, similar renovated properties in the same neighborhood may sell for around $325,000.
In that case, approximately $325,000 would be the property's estimated ARV.
ARV is commonly used by:
The key point is that ARV is not the property's current value.
It is an estimate of its potential market value after the planned improvements are completed.
ARV affects almost every part of a real estate investment analysis.
Investors use ARV to estimate:
Without a reasonable ARV, an investor may have no reliable way to determine whether a property is actually a good deal.
For example, imagine two properties are both available for $180,000.
Property A has an ARV of $250,000.
Property B has an ARV of $350,000.
Even though the purchase price is identical, the potential economics of the two deals are very different.
That's why investors typically calculate ARV before making an offer.
One of the easiest ways to understand ARV is to compare it with the property's current value.

For example:
As-Is Value: $200,000
Estimated Repairs: $50,000
ARV: $325,000
The investor now has a starting point for determining how much they should be willing to pay.
There isn't one universal mathematical formula that produces a reliable ARV for every property.
The most common approach is:
ARV = Estimated Market Value Based on Adjusted Comparable Sales
Investors estimate ARV by analyzing recently sold properties that are similar to the subject property and are already in the condition the subject property is expected to reach after renovation.
A simplified calculation might look like:
ARV = Adjusted Comparable Sale Values ÷ Number of Selected Comparables
However, simply averaging sale prices isn't always the best approach.
Investors should consider:
The goal is to determine what buyers are likely to pay for this specific property after renovation, not simply what nearby properties sold for.
Start by understanding the property you're evaluating.
Collect information such as:
You also need to determine what the property is expected to look like after renovation.
For example:
Will you install a basic rental-grade kitchen?
Or will you create a high-end kitchen comparable to the most expensive renovated homes in the neighborhood?
Your ARV depends on the finished product you're planning to create.
The next step is finding comparable properties, commonly called "comps."
Comps are recently sold properties that are sufficiently similar to the subject property to help estimate its market value.
Look for properties with similar:
Whenever possible, prioritize sold properties rather than active listings.
A property listed for $350,000 doesn't mean buyers will pay $350,000.
A recently sold property provides evidence of what buyers actually paid.
Many investors start with sales from the previous three to six months, depending on how active and rapidly changing the market is.
In a rapidly changing market, more recent sales may be more useful.
In slower markets with fewer transactions, investors may need to expand the search period.
The important thing is not to follow an arbitrary time limit.
Instead, ask:
Does this comparable still represent the market conditions and buyer demand for my property?
Older sales may still be useful when recent comparable transactions are limited, but they may require additional consideration for market changes.
There isn't a universal number of comps that works for every property.
A practical analysis may use three to five strong comparable sales, but the quality of the comps matters more than simply increasing the number.
For example:
Three highly similar renovated properties can be more useful than ten properties spread across different neighborhoods and price ranges.
Try to prioritize:
This is one of the most important parts of ARV analysis.
If you're calculating the value of a property after renovation, your best comps are generally properties that have already been renovated to a similar standard.
For example, imagine you're buying a property with:
You plan to completely renovate it.
Your ARV analysis should focus primarily on homes that buyers would view as comparable to your finished property.
Comparing the property to other distressed houses won't tell you much about its potential resale value after renovation.
Price per square foot can be useful as a secondary way to compare properties.
The basic formula is:
Price Per Square Foot = Sale Price ÷ Living Area
For example:
A renovated property sells for:
$320,000
Its living area is:
1,600 sq. ft.
Therefore:
$320,000 ÷ 1,600 = $200 per sq. ft.
If your subject property has 1,650 sq. ft., a simple estimate would be:
1,650 × $200 = $330,000
This does not mean the ARV is automatically $330,000.
Price per square foot should be used alongside other factors such as location, layout, condition, lot size, and property features.
It's a supporting metric, not a replacement for comparable-sales analysis.
No two properties are exactly the same.
This means you may need to adjust your comparable sales.
For example, suppose your subject property has:
But one comparable has:
The comparable may sell for more because of the garage.
You need to account for that difference when estimating your property's value.
Common factors to consider include:
Property FeaturePotential ImpactAdditional bathroomMay increase valueLarger living areaMay increase valueLarger lotMay increase valueGarageMay increase valueFinished basementMay increase valuePoolDepends heavily on local marketSuperior renovationMay increase valueInferior kitchenMay decrease valueInferior bathroomMay decrease valueDifferent neighborhoodCan significantly affect value
The size of each adjustment should be supported by local market evidence whenever possible rather than arbitrary assumptions.
Instead of treating ARV as one perfectly precise number, investors can create a reasonable range.
For example:
Conservative ARV: $315,000
Expected ARV: $325,000
Optimistic ARV: $335,000
This gives the investor a better understanding of potential outcomes.
If the deal only works when the property reaches the optimistic ARV, the investment may carry more risk than a deal that remains profitable under the conservative estimate.
This approach is especially useful when the comparable data isn't perfectly consistent.
Before using ARV to make an offer, review the analysis.
Ask:
For higher-value investments, investors may also consult a local real estate professional or qualified appraiser.
Let's walk through a simplified example.
Suppose you're evaluating a distressed property with:
Purchase Price: $180,000
Estimated Repairs: $45,000
You identify three renovated comparable properties:
ComparableSale PriceSizeProperty A$318,0001,580 sq. ft.Property B$325,0001,620 sq. ft.Property C$327,0001,640 sq. ft.
The average sale price is:
($318,000 + $325,000 + $327,000) ÷ 3
= $323,333
If the properties are sufficiently comparable and no major adjustments are required, you could use approximately $323,333 as a starting ARV estimate.
However, a professional analysis would also review differences between the properties before finalizing the estimate.
Now suppose Property B has an additional bathroom that your subject property doesn't have.
If local market evidence suggests that this feature contributes approximately $10,000 in value, you could adjust Property B downward:
$325,000 − $10,000 = $315,000 adjusted value
Your adjusted comps might now look like:
Average adjusted value:
($318,000 + $315,000 + $327,000) ÷ 3
= $320,000
Your estimated ARV would therefore be approximately:
$320,000
This illustrates why simply averaging sale prices without considering property differences can produce misleading results.
Once you've estimated ARV and repair costs, you can begin calculating your Maximum Allowable Offer (MAO).
A commonly used investor formula is:
MAO = (ARV × 70%) − Repair Costs
The 70% figure is a rule of thumb, not a universal requirement.
Investors may use different percentages depending on:
Suppose:
ARV = $320,000
Repairs = $45,000
Using the 70% rule:
$320,000 × 70% = $224,000
Then:
$224,000 − $45,000 = $179,000
Estimated MAO:
$179,000
This doesn't mean $179,000 is automatically the correct offer.
It's a screening calculation.
A complete deal analysis should also consider additional costs such as:
These two numbers serve different purposes.
ARV tells you what the property could potentially be worth after renovation.
MAO helps determine how much you may be willing to pay for the property.
For example:
ARV: $320,000
Repairs: $45,000
MAO using 70% rule: $179,000
The ARV estimates the property's potential finished value.
The MAO helps establish a purchase-price ceiling based on a particular investment strategy.
Investors can use multiple sources when researching comparable properties.
Common sources include:
Each source has different data coverage and features.
For serious investment decisions, it's often useful to cross-check information instead of relying on a single website.
An asking price represents what a seller wants.
A sold price represents what a buyer actually paid.
Whenever possible, use completed sales for your primary comparable analysis.
Two properties can be only a few blocks apart and still have significantly different values.
Neighborhood boundaries, school zones, property types, local amenities, and buyer demand can all affect prices.
A 1,500-square-foot starter home shouldn't automatically be compared with a 3,000-square-foot luxury property.
Look for similarities in:
A basic renovation and a high-end renovation don't necessarily produce the same resale value.
Your ARV assumptions should match the actual level of renovation you plan to complete.
A $30,000 renovation can quickly become a $45,000 renovation if unexpected problems appear.
Common surprises include:
Whenever possible, use contractor estimates and property inspections to improve the repair budget.
Finding one property that sold for $350,000 doesn't automatically mean your property will sell for $350,000.
The highest sale may have:
ARV should be based on the overall comparable set rather than the most attractive number.
A comparable sale from several months ago may not perfectly represent today's market.
Consider:
AI can make property analysis significantly faster.
Depending on the available data, AI-powered real estate software can help analyze:
AI can also help investors organize large amounts of property data and surface potentially relevant comparable properties.
However, AI-generated ARV estimates should be treated as analysis support rather than guaranteed valuations.
The quality of an AI estimate depends on the quality, coverage, freshness, and methodology of the underlying data.
Investors should still validate important assumptions before making a purchase decision.
Manually calculating ARV for every property can become time-consuming when you're analyzing dozens of leads.
An ARV calculator can help investors quickly organize:

Comparable Sales
↓
Adjusted Comp Values

This can turn a process that requires multiple spreadsheets and browser tabs into a more structured workflow.
For investors analyzing a large number of properties, the real advantage isn't simply calculating one ARV faster.
It's being able to analyze more opportunities consistently.
ARV is only one part of the investment process.
A typical wholesaling or flipping workflow might look like:

Managing these steps manually can become difficult as the number of leads increases.
That's where a real estate CRM can help investors organize property information, track leads, manage follow-ups, and keep deal analysis connected to the rest of the sales process.
A CRM can help investors keep important property information in one place.
For example, an investor could track:
Instead of moving between spreadsheets, notes, email, and multiple property tools, investors can build a centralized workflow around their acquisition process.
For real estate wholesalers and investors managing a large pipeline, this can make it easier to identify which properties require attention and which deals have progressed to the next stage.
ARV is an estimate, not a guaranteed selling price.
Its accuracy depends on the quality of:
A strong ARV analysis uses multiple pieces of evidence rather than relying on a single comparable or automated estimate.
For high-value transactions, investors should consider getting professional advice from qualified real estate professionals, contractors, lenders, appraisers, or other specialists where appropriate.
ARV is one of the most important numbers in real estate investing because it helps investors understand what a property may be worth after renovations.
But calculating ARV isn't simply about finding three nearby properties and averaging their prices.
A reliable ARV analysis involves:
Finding relevant sold comps → Comparing property characteristics → Adjusting for differences → Considering price per square foot → Estimating a realistic ARV range → Validating the assumptions
Once you have an ARV, you can use it alongside repair costs, financing expenses, holding costs, selling costs, and your desired return to determine whether a property fits your investment strategy.
Technology can make this process faster.
AI tools, property-data platforms, ARV calculators, and real estate CRMs can help investors organize information and analyze opportunities more efficiently.
But the quality of the deal still depends on the quality of the assumptions behind the numbers.
For investors who analyze multiple properties every week, bringing property data, ARV calculations, offers, and follow-ups into one organized workflow can make the acquisition process significantly easier.

ARV stands for After Repair Value. It is the estimated market value of a property after planned repairs and renovations have been completed.
ARV is generally estimated by analyzing recently sold comparable properties that are similar to the subject property and have a similar expected renovation condition. Investors then adjust the comparable values for differences such as size, bathrooms, garages, lot size, and other relevant features.
There isn't one universal formula for ARV. A common approach is to estimate the property's value using adjusted comparable sales. A simplified method is to calculate an average or median of appropriately selected and adjusted comparable values.
The 70% rule is a commonly used investor rule of thumb for estimating a maximum purchase price:
MAO = (ARV × 70%) − Repair Costs
The 70% percentage is not a universal requirement. Investors may adjust it based on market conditions, financing, holding costs, selling costs, and their investment strategy.
No. ARV represents the estimated value of the property after repairs. Repair costs are separate and are typically deducted when calculating an investor's potential offer or profitability.
Market value can refer to the property's estimated value under current market conditions and current condition. ARV specifically refers to the estimated value after planned renovations have been completed.
There is no universal number. Many investors begin with three to five strong comparable sales, but the relevance and quality of the comps are more important than simply increasing the number.
Ideally, your primary comps should be in a condition similar to what you expect the subject property to look like after renovation. This helps make the comparison more relevant.
Zillow provides automated home-value estimates, but an investor calculating ARV should generally analyze relevant sold comparable properties and consider renovation condition, property characteristics, and local market conditions rather than relying on one automated estimate.
AI can help analyze property data, identify potentially relevant comps, and estimate values, but AI-generated estimates should be validated against reliable comparable sales and local market information before being used for an investment decision.
MAO stands for Maximum Allowable Offer. It is an investor's calculated purchase-price ceiling based on factors such as ARV, repair costs, transaction costs, financing, and desired returns.
No. ARV can also be useful for wholesalers, BRRRR investors, private lenders, hard money lenders, developers, and other real estate professionals evaluating properties that require renovation.
The most reliable approach is to use relevant, recently sold comparable properties, adjust for meaningful differences, account for the expected renovation quality, and validate the result against current local market conditions.
