How Investors Calculate Cash Offers in St. Louis
A cash offer can feel simple: no repairs, no showings, no buyer financing, and a closing date that may be measured in days instead of months. But the number on the offer is not random. Most investors back into that number from a resale value, a repair estimate, holding costs, selling costs, risk, and profit. If you understand the math, you can tell the difference between a fair convenience discount and a buyer trying to take more than the situation justifies.
This matters in St. Louis because condition and marketability change dramatically from one neighborhood to the next. A brick bungalow in South City, a ranch in South County, a vacant property in North County, and an inherited house in Oakville may all attract cash buyers, but the investor spreadsheet will not treat them the same. The point is not that every cash offer is bad. The point is that a seller should know what the investor is subtracting before signing away the upside.
The basic cash-offer formula
Most serious investors start with ARV, or after-repair value. That is what they believe the house could sell for after repairs, cleanup, updates, and resale preparation. From there they subtract repairs, resale costs, holding costs, closing costs, risk, and their profit target. Wholesalers may also subtract an assignment spread, which is the margin they hope to make by assigning the contract to another buyer.
A simplified version looks like this: after-repair value minus repairs minus selling costs minus holding costs minus risk cushion minus investor profit equals the maximum offer. The buyer may start lower than that maximum because negotiation is part of the business model.
A realistic St. Louis example
Assume a house might resell for $240,000 after updates. The investor expects $38,000 in repairs, $18,000 in resale and closing costs, $6,000 in insurance, utilities, taxes, interest, and holding time, and $12,000 as a risk cushion. If the investor wants $35,000 in profit, the math lands around $131,000 before negotiation. If a wholesaler wants a $10,000 assignment fee, the offer could fall closer to $121,000.
That does not mean the seller should automatically list. It means the seller should compare the offer with the likely net from listing as-is. If the same house could list as-is for $175,000 and net $160,000 after commissions, concessions, repairs, and time, a $121,000 cash offer may be too expensive unless speed and certainty are worth the gap.
Which deductions are real?
Repairs are real when they are specific. Roof age, foundation movement, sewer lateral issues, water intrusion, and deferred maintenance all affect resale value. Vague deductions like market risk or Unknown repairs deserve pressure.
Where sellers can negotiate
Use the Cash Offer Decoder to test whether the discount is really paying for speed or widening the spread. Proof of funds matters too. Read how to verify proof of funds. If the buyer reserves the right to inspect and lower the price, read the guide on retrading.

The bottom line
Use the cash buyer question checklist, compare your listing net, and make the decision with your eyes open.
