After Repair Value Calculator

Use this calculator to estimate after repair value from comparable sale price and property size adjustment. It helps investors create a quick ARV estimate for renovation and flip analysis.

What this calculator does

The after repair value calculator adjusts a comparable sale price by relative property size.

It uses:

• comparable sale price
• subject property size
• comparable property size
• adjusted value estimate

This gives a simplified ARV estimate for early-stage deal screening.

How to use the after repair value calculator

Enter the comparable sale price, the subject property size, and the comparable property size. Use the same unit for both size inputs, such as square metres or square feet.

This method assumes size is the main adjustment. In practice, condition, location, layout, land, and finish quality also matter.

After Repair Value Formula

ARV = comparable sale price x subject size / comparable size

Where subject size is the property being assessed and comparable size is the sold property used as the benchmark.

Example calculation

If:

• Comparable sale price = 500,000
• Subject size = 120
• Comparable size = 100
• ARV = 600,000

A subject property that is 20% larger than a 500,000 comparable has a simplified ARV of 600,000.

What is after repair value?

After repair value is the estimated value of a property after planned repairs or improvements are completed.

ARV is commonly used by renovators and flippers to decide whether the purchase price and renovation budget leave enough resale margin.

Interpreting your result

The result is a simplified estimate, not a formal valuation. It is most useful when the comparable property is very similar and recently sold.

Use ARV with the 70 percent rule and property flip profit analysis to test whether a deal has enough margin.

When to use this calculator

Use this calculator when you want to:

• estimate resale value
• screen renovation deals
• adjust comparable sales
• test flip assumptions

Common mistakes

Common mistakes include:

• comparing unlike properties
• mixing size units
• ignoring location differences
• treating ARV as guaranteed value

FAQs

Is ARV the same as market value?

ARV is an estimated future value after repairs, while market value usually reflects current condition.

What if both properties are the same size?

If sizes are equal, the ARV equals the comparable sale price.
