ARV calculator

An after-repair value worksheet for investor offer math.

Use this ARV calculator structure to estimate a post-renovation value, explain the comparable sales behind it, and translate the number into a maximum allowable offer. It is built for investors and agents who need a defensible value range before writing an offer.

Subject property

Address, beds, baths, square footage, lot size, year built, current condition, and planned repair scope

Retail comps

Three to six renovated closed sales that match the post-repair version of the property

Adjustments

Line-item changes for size, condition, location, lot, garage, basement, pool, view, and timing

After-repair value

Adjusted comp range with a conservative ARV, likely ARV, and stretch ARV

Offer ceiling

ARV minus repairs, selling costs, holding costs, financing, and target profit

How to calculate ARV without fooling yourself

01

Define the finished product first

Write down the property condition you plan to deliver after repairs. ARV should compare the future finished home against renovated sales, not the current distressed condition.

02

Use closed retail comps, not active wish prices

Prioritize nearby closed sales that already reflect the quality level you expect after renovation. Active listings can help show competition, but closed sales anchor the valuation.

03

Adjust each comp before averaging

Do not average raw sale prices if the comps differ in size, condition, garage count, lot, basement, view, or timing. Adjusted sale prices give a cleaner ARV range.

04

Convert ARV into a maximum allowable offer

Subtract repairs, contingency, selling costs, holding costs, financing, and required profit from the conservative ARV. If the deal only works at the stretch ARV, the margin is thin.
