How Cash Home Buyers Calculate Their Offers

When a cash buyer makes you an offer, it's not a guess or a low-ball instinct. It's the output of a specific formula that accounts for the property's future value, the cost to get it there, and the buyer's required return. Understanding the formula helps you evaluate any offer you receive — and negotiate from an informed position.

Step 1: Determine the After-Repair Value (ARV)

The ARV is the estimated market value of the property after it has been fully renovated and is ready for a retail buyer. This is the ceiling — everything else is subtracted from it.

How ARV is determined:

• Pull "comps" — recent sales of similar properties in the same neighborhood
• Focus on properties that have been updated/renovated (not distressed sales)
• Adjust for size, lot, age, and features
• For DFW specifically: use the same zip code or subdivision when possible; DFW market values can change dramatically street by street

This is where a good buyer does real work. A lazy buyer may use a Zillow estimate, which can be significantly off. A thorough buyer pulls actual MLS sales data and knows the neighborhood.

Step 2: Estimate Repair Costs

The buyer (or their contractor) walks the property and estimates the cost to renovate it to retail-ready condition. This typically includes:

Repair estimates are the most subjective part of the formula. Two buyers looking at the same house may produce estimates that differ by $20,000–$40,000 depending on their experience, their contractor relationships, and whether they plan a cosmetic flip or a full renovation.

Step 3: Calculate Holding Costs

From the day the buyer purchases until the day they resell, they incur costs:

• Financing costs — if using hard money or private loans, rates of 10–15% annually on the purchase price
• Property taxes — DFW property taxes run ~2–2.5% annually
• Insurance — builder's risk policy during renovation
• Utilities — must be maintained during renovation

For a 4-month renovation and sale period, holding costs on a $250,000 property can easily run $8,000–$15,000.

Step 4: Calculate Selling Costs

When the investor resells the renovated property, they incur their own selling costs:

• Agent commissions: 5–6% of resale price
• Closing costs: 1–2%
• Staging and photography: $1,000–$3,000

On a $320,000 resale, selling costs can total $20,000–$25,000.

Step 5: Apply the Profit Margin

After all costs, the buyer needs a profit margin — their return for taking on renovation risk, market risk, and capital deployment. Typical target: 10–20% of ARV, or a minimum dollar threshold ($25,000–$50,000 depending on deal size).

Putting It All Together: The Full Formula

Why Offers Vary Between Buyers

If you get multiple cash offers and they're different (sometimes significantly), it's because buyers use different inputs:

• Different ARV comps (local market knowledge varies)
• Different repair estimates (experienced vs. inexperienced estimators)
• Different profit targets (a buyer with lower overhead can offer more)
• Different financing costs (cash-heavy buyers have no hard money interest)

This is why getting multiple offers is smart — and why you should ask every buyer to walk you through how they calculated the number.
