One of the most common questions we hear is: "How did you arrive at this number?" It's a fair question — and one every reputable cash buyer should answer transparently. This guide pulls back the curtain on how cash offers are calculated, so you can evaluate any offer with confidence.
Red Flag Warning
If a cash buyer won't explain how they arrived at their offer — or if the explanation doesn't make sense — that's a red flag. Reputable buyers are transparent about their methodology. You should never feel like a number was pulled out of thin air.
The Cash Offer Formula
Most reputable cash buyers use some version of this formula:
Cash Offer = ARV − Repair Costs − Holding Costs − Selling Costs − Profit Margin
Let's break down each component.
Component #1: After-Repair Value (ARV)
The ARV is what the home would sell for if all needed repairs and renovations were completed — in other words, its full market potential. Cash buyers determine ARV by analyzing comparable sales (comps) of fully renovated, similar homes in your neighborhood that have sold recently.
For example: if similar renovated 3-bedroom homes in your area sell for $200,000–$220,000, the ARV might be set at $210,000. The ARV is the starting point, not the offer. Everything gets subtracted from here.
Component #2: Estimated Repair Costs
This is the biggest deduction — and the one that varies most from house to house. The buyer estimates what it will cost to bring the property from its current condition to the condition reflected in the ARV. This includes:
- Major systems: roof, HVAC, electrical, plumbing
- Structural: foundation, basement waterproofing
- Interior: kitchen, bathrooms, flooring, paint, drywall
- Exterior: siding, windows, landscaping, driveway
- Cleanup: debris removal, junk hauling, pest remediation
A reputable buyer will share their repair estimate with you. This is where you can see exactly why two seemingly similar homes might get very different offers — one needs a $12K roof while the other's roof has 10 years of life left.
Component #3: Holding Costs
The buyer will own the property during renovations and while it's listed for resale — typically 4–9 months. During that time, they pay property taxes, insurance, utilities, loan interest (if using financing), and maintenance. On a typical Michigan property, holding costs run $1,000–$2,500/month. For a 6-month project, that's $6,000–$15,000.
Component #4: Selling Costs
When the buyer eventually resells the renovated property, they'll pay agent commissions (5–6%), closing costs, and possibly staging/photography. On a $210,000 resale, that could mean $14,000–$16,000 in selling costs. These get factored into the initial offer.
Component #5: Profit Margin
Cash buyers are businesses — they need to make a profit to stay in business. Typical margins range from 10–15% of the ARV. A buyer who's transparent about their margin isn't being greedy; they're being honest about running a sustainable business that can continue helping homeowners.
A Real Example: Putting It All Together
Here's how the formula works for a hypothetical 3-bedroom home in Midland:
If the buyer's repair estimate is accurate and the ARV is realistic, this is a fair offer. The homeowner gets $113,700 cash with no repairs, no commissions, no holding costs, and closing in 7–14 days. Compare that to spending $45,000 on repairs, waiting 6 months, paying $15,000 in commissions — all for uncertain net proceeds.
