How Cash Home-Buying Offers Are Calculated (No Lowballing)
How do cash buyers calculate their offer?
A legitimate cash offer is calculated from the home's after-repair value (ARV) — what it would sell for fully fixed up — minus the cost of repairs, minus the buyer's selling and holding costs, minus a reasonable profit margin. Understanding this ARV-minus-costs formula lets you tell a fair offer from a lowball and ask the right questions. A trustworthy buyer will walk you through every number.
Key takeaways
- ✓ Offer ≈ After-Repair Value (ARV) − repair costs − selling/holding costs − a reasonable profit margin.
- ✓ ARV is what the home would sell for fully renovated, based on comparable sales.
- ✓ A common rule of thumb is roughly 70% of ARV minus repairs.
- ✓ A fair buyer shows you the math; a lowball arrives with no explanation and pressure.
- ✓ Always ask: how did you arrive at this number?
The phrase “cash offer” can feel like a black box, and a few aggressive operators exploit that by throwing out lowball numbers and hoping you’re too stressed to push back. The fix is simple: understand the formula. Once you do, you can evaluate any offer in minutes.
The formula every legitimate buyer uses
Virtually all real cash offers come from the same equation:
Offer = After-Repair Value − Repair Costs − Selling & Holding Costs − Profit Margin
Let’s break down each piece.
1. After-Repair Value (ARV)
ARV is what your home would sell for fully renovated, based on recent sales of comparable homes nearby. A buyer pulls “comps” — similar properties by size, age, and location that sold recently — to estimate this number. This is the same comp-based approach an appraiser or agent uses.
2. Repair costs
Next, the buyer estimates what it will cost to bring the home to that renovated condition — roof, systems, kitchen, baths, cosmetics, and any structural issues. On a dated or distressed home, this can be substantial, and it comes directly off the top.
3. Selling and holding costs
Even a cash buyer eventually resells, and that has real costs: agent commissions on the resale, the New Jersey Realty Transfer Fee, insurance, property taxes, and utilities while the home is renovated and re-listed. These are predictable expenses, not padding.
4. Profit margin
Finally, the buyer builds in a margin for the risk and capital involved. A reasonable margin is legitimate — it’s how the business survives. An excessive margin disguised as “that’s just what we can do” is where lowballing hides.
A simple example
Suppose a Camden County home would be worth $300,000 fixed up (ARV), needs $60,000 in repairs, and carries $30,000 in selling/holding costs and margin. A fair cash offer lands around $210,000 as-is. If a buyer offers $150,000 with no explanation, you now know to ask why.
How to spot a fair offer vs. a lowball
- Fair buyers show their work — the comps, the repair estimate, the cost assumptions.
- Lowball operators give you a number with no breakdown, apply pressure to sign fast, or won’t justify their math.
- Ask for the comps. If the ARV seems low, recent neighborhood sales will show it.
- Get a second opinion. A trustworthy buyer won’t object to you comparing offers.
