Cash buyers do not pick numbers at random. Every legitimate offer is built from the same four-part formula, starting with what your home would be worth once it is repaired and ready to sell. Understanding how cash home buyers calculate their offers gives you the ability to evaluate any offer you receive and spot the difference between a fair price and one that does not reflect your property’s real value.
The ARV Formula Cash Buyers Use
Offer = After-Repair Value minus Repair Costs minus Holding and Closing Costs minus Buyer Margin
These four inputs drive every offer:
After-Repair Value (ARV): The estimated price your home would command on the open market if it were fully renovated and in move-in condition. Buyers derive this number from recent comparable sales — homes similar in size, age, style, and location that sold in the past 60 to 90 days. ARV is the ceiling the offer works down from.
Repair Costs: The estimated budget to bring the home from its current condition to the ARV condition. This includes contractor labor, materials, permits, and a contingency buffer for surprises. Experienced buyers are conservative with this number because cost overruns come out of their margin, not yours.
Holding and Closing Costs: The costs the buyer incurs from the day they purchase the property to the day they resell it. This includes property taxes, insurance, utilities, any financing costs if the buyer uses a private credit line, and transaction costs at both the purchase closing and the resale closing. This figure typically represents 3 to 5 percent of ARV, depending on how long the renovation takes.
Buyer Margin: The profit the buyer requires to take on the project. This compensates them for the capital deployed, the risk of unexpected repair issues, and the work of managing the renovation. For direct cash buyers, this is typically 10 to 15 percent of ARV.
A Worked Example With Real Numbers
Take a home with these characteristics:
- ARV based on recent comparable sales: 300,000 dollars
- Estimated repairs (new roof, kitchen update, bathroom refresh, flooring): 45,000 dollars
- Holding and closing costs (estimated 7-month renovation and resale cycle): 18,000 dollars
- Buyer margin at 12 percent of ARV: 36,000 dollars
Offer = 300,000 minus 45,000 minus 18,000 minus 36,000 = 201,000 dollars
That offer is 99,000 dollars below the retail ARV. The gap looks large. Now compare what a seller would actually net from a traditional sale on the same property:
| Item | Traditional Sale | Cash Sale |
|---|---|---|
| Sale price or offer | $300,000 | $201,000 |
| Agent commission (5.5%) | -$16,500 | $0 |
| Seller closing costs (2%) | -$6,000 | $0 |
| Pre-listing repairs to attract buyers | -$30,000 | $0 |
| Carrying costs while listed (4 months) | -$7,200 | $0 |
| Net to seller | $240,300 | $201,000 |
The actual difference in net proceeds is approximately 39,000 dollars, not 99,000 dollars. For a property that needs less work, or that would sit on the market longer in a slow area, the gap narrows further. Use the HomeWise net proceeds calculator to run this comparison with your specific numbers.
What Is ARV and How Is It Calculated?
ARV stands for after-repair value. It is the estimated resale price of a property in good, fully renovated condition, calculated from recent comparable sales in the same neighborhood.
Buyers identify comparables by looking for homes that:
- Sold within the past 60 to 90 days
- Are within 0.25 to 0.5 miles of your property
- Have similar square footage, bedroom and bathroom count, and lot size
- Are in the condition the buyer intends to renovate your property to
The ARV is not a formal appraisal and it is not a guaranteed price. It is a data-driven estimate of what the renovated home would realistically sell for. You can spot-check any buyer’s ARV by searching recent sold prices on Zillow, Redfin, or your county recorder’s website for similar homes in your area. If the buyer’s ARV does not align with what you find, ask them to explain the specific comparables they used.
How to Tell if the Offer You Received Is Fair
A fair cash offer is transparent. A legitimate buyer should be able to share the following without hesitation:
- The ARV they are using and the specific comparables that support it
- Their repair estimate and what the major line items are
- Their holding cost assumptions (how long they expect the renovation to take)
- Their margin percentage
When you have those four numbers, you can evaluate each one:
- Does the ARV match what similar homes near you have actually sold for?
- Is the repair estimate reasonable for the scope of work the home actually needs?
- Is the buyer margin in the 10 to 15 percent range, or significantly higher?
If the buyer cannot walk you through those inputs or deflects your questions, that is meaningful. A buyer who is confident in their formula will explain it clearly. A buyer who is trying to lowball you will avoid the conversation.

The Variables That Affect the Offer Size
Two factors most heavily influence where your offer lands within the typical 70 to 85 percent of ARV range:
Repair scope. The more extensive the work, the lower the offer relative to ARV. A home that needs only cosmetic updates (paint, flooring, fixtures) will see a higher offer percentage than a home that needs a new roof, HVAC, and foundation repairs.
Local market speed. In markets where renovated homes sell quickly, buyers can use a shorter holding cost assumption, which reduces that line item and allows them to offer more. In slower markets, longer expected hold times increase holding costs and compress the offer.
A buyer who is experienced in your specific market will reflect those local realities in both the ARV and the holding cost line. A buyer who is not familiar with your area may use generic assumptions that do not accurately represent your market.
The Bottom Line
Cash buyers calculate offers by working backward from after-repair value: ARV minus repairs minus holding costs minus margin equals their offer. The formula is transparent and repeatable. When a buyer explains it to you, you can evaluate each component yourself.
If you want to see how this formula applies to your specific property, request a no-obligation cash offer from HomeWise. We will share every number — ARV, repair estimate, and our costs — so you can compare the offer to your realistic net from a traditional listing and make the decision that fits your situation.
