Short answer: Many investment buyers start with what a property could reasonably sell or rent for, then subtract expected repairs, acquisition and selling expenses, carrying costs, and a margin for risk and return. That calculation is a decision tool, not a universal formula used by every cash buyer. A buyer purchasing a rental may calculate differently from one renovating and reselling the property.
Understanding the math helps you have a better conversation about a Florence cash offer—even if you ultimately decide to list the house instead.
Step 1: Establish a realistic property value
First distinguish between three figures that are often mixed together:
- Current as-is value: What a knowledgeable buyer might pay for the house in its present condition.
- After-repair value (ARV): A reasoned estimate of what the property might sell for after a specified renovation.
- Seller’s target price: The amount the owner hopes to receive. This matters in negotiation but is not proof of value by itself.
A buyer may review recently sold comparable homes in Florence and the Shoals, accounting for square footage, lot characteristics, condition, layout and location. Comparing a modest older house with a newly renovated one without adjusting for those differences can inflate expectations.
Step 2: Estimate what must happen after purchase
An investor might need to budget for items such as roofing, HVAC, plumbing, electrical work, kitchens, bathrooms or structural repairs. Labor, materials, permits and unknown problems can change the budget. A buyer should distinguish visible issues from conditions not yet inspected.
The renovation budget is not necessarily the same as what you would spend to make the house livable. A buyer preparing a resale may choose a different scope, and another buyer may keep the property as a rental.
Step 3: Account for the transaction and holding period
The purchase is not the last expense. Depending on the strategy, costs may include title or closing expenses, insurance, utilities, property taxes, maintenance, financing costs, resale marketing and brokerage services. A longer-than-expected project can increase these costs.
The buyer also considers the chance that repairs cost more than expected or that the eventual resale price comes in lower than projected. Those risks influence the amount they are willing to pay.
Step 4: Test the numbers with a hypothetical worksheet
Illustration only — not a Florence market estimate or an offer from We Buy Houses In Florence:
| Estimated project item | Assumed amount |
|---|---|
| Possible after-repair resale price | $220,000 |
| Renovation budget | −$32,000 |
| Holding and carrying costs | −$14,000 |
| Future resale and transaction costs | −$16,000 |
| Target margin for risk and return | −$27,000 |
| Illustrative maximum purchase amount | $131,000 |
That worksheet is not a promise that any real buyer would offer $131,000—or that the home is worth $220,000. Change the repairs, timing, resale value, or buyer’s required margin, and the result changes.
In practice, a buyer may use a different model, and some expenses overlap if not categorized carefully. Ask which assumptions are included so that costs are not counted twice.
Step 5: Understand why two offers differ
Suppose one buyer expects $20,000 in repairs while another expects $40,000. One intends to rent the property; another plans to renovate and sell. One has a contractor available next week; the other needs several months. Those differences can lead to different offers without either buyer necessarily misrepresenting the house.
What you should watch for is a buyer who refuses to explain major price changes or repeatedly revises the offer without identifying new information. Request any revised terms in writing.
What can a homeowner do with this information?
Before requesting a quote, prepare a short property fact sheet: square footage, year built if known, roof and HVAC ages if known, major defects, current occupancy, liens or mortgages, and your preferred closing window. If a buyer’s number seems low, ask whether the disagreement is about market value, repair scope, transaction costs or risk.
You do not need to adopt the investor’s formula. You need to decide whether the written purchase price, net proceeds and conditions suit your situation. If you have sufficient time and funds to repair or list, that may be the better financial route.

Frequently asked questions
Do all buyers use the “70% rule”?
No. Some investors use rules of thumb, but a single percentage of after-repair value is not a reliable local pricing standard. A detailed property-specific budget is more informative.
Are cash offers based only on square footage?
No. Layout, neighborhood, lot, condition, occupancy, market demand and repair costs can be just as consequential.
Can I challenge a buyer’s repair estimate?
You can ask questions, supply contractor quotes, or seek another offer. A buyer may still have a different budget or risk tolerance.
Bottom line: A credible calculation connects real property facts to a written offer. Use the worksheet as a way to ask better questions, not as a substitute for a property valuation.
