## The short answer

Cash offers are low because the investor pays for repairs, months of taxes, insurance and interest, closing costs on both ends and the resale commission, and still needs a profit for the risk. Many use the 70% rule of thumb: 70% of after-repair value minus repairs. On an illustrative $300,000 Waterbury house needing $60,000 of work, that's a $150,000 maximum offer. Connecticut's conveyance tax on the resale alone is 1.25% there (CGS 12-494).

Key takeaways

- **Cash offers from investors are low because the investor pays for everything after you leave:** repairs, months of taxes, insurance and loan interest, the costs of reselling, and the risk that something goes wrong. Their profit, and any [wholesaler's fee](/what-is-real-estate-wholesaling/), has to fit in what's left.

- **Many investors start from a rule of thumb, the "70% rule":** 70% of what the house will sell for after repairs, minus the repairs. It's a starting point, not a law, and not every investor uses it.

- **A low offer isn't automatically an unfair one,** and a high one isn't automatically honest. What matters is whether the math is real and whether you'd keep more another way.

- **If you can fund and manage the repairs and wait, you'll usually keep more by fixing and listing.** The gap is what you're paying someone else to take the work and the risk.

- **Heirs should get an independent value first.** Inherited houses attract a lot of offers, and selling soon after a death often has little tax benefit to selling cheap.

## Why are cash offers on houses so low?

Cash offers on houses are low because an investor's price has to leave room for the repairs, the months of holding costs, the costs of buying and reselling, and a profit large enough to justify the risk. Many investors work backward from what the house will sell for once fixed, using a rule of thumb such as the 70% rule, so the offer sits well below that number.

If you got a cash offer that made your stomach drop, you're not alone, and you're not wrong to question it. A number far below what you've seen on listing sites feels like an insult. Sometimes it is a lowball. Often it's what the math leaves once you count every cost an investor pays that you won't see.

This page shows that math, step by step, with a Connecticut house as the illustration. It's part of our series that starts with [what real estate wholesaling is](/what-is-real-estate-wholesaling/), because many cash offers come from wholesalers, and their fee sits inside the same math. You'll also see when you should turn a cash offer down and list instead.

One note first: "cash" describes how a buyer pays, not who they are. Some retail buyers pay cash for a house they'll live in, and they pay retail prices. This page is about investor cash offers, the kind that come from "we buy houses" companies, flippers, landlords and wholesalers.

## How do investors calculate a cash offer on a house?

Investors calculate a cash offer by estimating the after-repair value (what the house will sell for once fixed), subtracting the repairs, and then subtracting a margin to cover holding costs, buying and selling costs and their profit. A common rule of thumb, the 70% rule, sets the maximum offer at 70% of after-repair value minus repairs.

Here's the rule of thumb, in the form investors use it:

The 70% rule (an investor rule of thumb)Maximum offer = (after-repair value × 70%) − repair costs. The 30% that's held back is meant to cover the investor's buying, holding and selling costs plus their profit. Many investors adjust the percentage depending on the market, the house and their own costs, and landlords often price from rent instead.

Three numbers drive every investor offer, so it's worth knowing what each one means:

- **After-repair value (ARV).** What similar, fixed-up houses nearby have recently sold for. Not what your house is worth today as it is. Not the list price of houses still on the market.

- **Repair costs.** What it will cost the investor to bring the house up to the standard of those comparable sales, paying contractors, permits and materials, plus a cushion for surprises.

- **The margin.** Everything else: interest, taxes, insurance, utilities, closing costs on both ends, the agent who sells it afterward, and profit.

The rule exists because investors need a quick way to say yes or no to dozens of houses. It also explains why two houses with the same "value" can get very different offers: the repairs and the risk are different.

## Where does the money go between a cash offer and the resale price?

The money between a cash offer and the resale price goes to repairs, interest on the money borrowed, property tax, insurance and utilities during the work, the investor's closing costs, the agent commission and transfer tax on the resale, and whatever is left as profit. On an illustrative Connecticut house, those costs take about half of the 30% margin.

Illustrative example. The house, the after-repair value, the repair estimate and every line marked "assumption" are made up to show the math. They are not a typical deal, a typical cost or a promise. The tax and insurance lines use published Connecticut figures.

Picture a single-family house in Waterbury that needs a new kitchen, a bathroom, a boiler and paint throughout. Fixed up, similar houses nearby sell for about $300,000. The investor estimates $60,000 of repairs and six months from purchase to resale.

The 70% rule gives: $300,000 × 70% = $210,000, minus $60,000 of repairs = **a maximum offer of $150,000**. Here's where the other $90,000 goes:

| Cost | Amount | Where the number comes from |
| --- | --- | --- |
| Investor's attorney and title costs to buy | $2,000 | Assumption |
| Property tax, 6 months | $4,260 | About $710 a month: Waterbury's FY2027 mill rate of 43.34 on the town's $280,000 median single-family sale price |
| Insurance, 6 months | $1,020 | Connecticut's average homeowners premium, $2,036 a year (NAIC, 2023 data). A vacant house under renovation may cost more to insure. |
| Utilities, 6 months | $1,500 | Assumption: heat, power and water during the work |
| Interest and lender fees | $16,800 | Assumption: $210,000 borrowed at 12% interest-only for 6 months, plus 2 points |
| Agent commission on the resale | $15,000 | Assumption: 5% of $300,000. Commissions are negotiable. |
| Conveyance tax on the resale | $3,750 | 1.25% in Waterbury: 0.75% state plus 0.50% town (CGS 12-494) |
| Investor's attorney to sell | $1,500 | Assumption |
| Total costs besides repairs | $45,830 | |
| Left for profit and risk | $44,170 | Before income tax, and only if repairs, timing and the resale price all go to plan |

So the investor puts about $256,000 into the house (purchase, repairs and costs) to sell it for $300,000. If the boiler job turns into a chimney job, or the resale takes four extra months, or prices dip, most of that $44,000 can disappear. That risk is the main reason the margin exists.

Your side of the same deal: you'd sell for $150,000 and pay Connecticut's conveyance tax as the seller, $1,875 at Waterbury's 1.25%, plus your own attorney. No commission, no repairs, no months of carrying costs.

## Would you keep more by fixing the house and listing it yourself?

You would usually keep more by fixing the house and listing it yourself, if you can pay for the repairs, manage the contractors and wait several months. In the illustrative example, the owner would keep roughly $66,000 more than the cash sale. That difference is what the investor is paid for funding the work, managing it and carrying the risk.

Here's the same illustrative house, sold three ways:

| | Cash sale as-is | Fix it yourself, then list |
| --- | --- | --- |
| Sale price | $150,000 | $300,000 |
| Repairs | $0 | −$60,000 |
| Holding costs, 6 months (tax, insurance, utilities) | $0 | −$6,780 |
| Agent commission (assumption: 5%) | $0 | −$15,000 |
| Seller's conveyance tax, Waterbury 1.25% | −$1,875 | −$3,750 |
| Your attorney (assumption) | −$1,500 | −$1,500 |
| What you keep before your mortgage payoff | $146,625 | $212,970 |
| Cash you need up front | None | $60,000 plus six months of carrying costs |
| Risk if repairs or the market go wrong | The buyer's | Yours |

On paper the listing wins by about $66,000. Whether that's real for you depends on questions only you can answer:

- Do you have $60,000 to spend, or could you borrow it, and at what cost?

- Can you find, schedule and supervise contractors, possibly from out of state?

- What happens if the repairs uncover more, as they often do in older Connecticut houses?

- Can you carry the mortgage, taxes and insurance for six months or longer?

- Is there a deadline, such as a Law Day, a probate order or a move, that the timeline won't survive?

If those answers are yes, fixing and listing is likely the better deal, and you should do it. If they're no, the "extra" money was never really available to you. There's also a middle road: a light cosmetic refresh and a listing, or a fix-and-list partnership, where an investor funds the repairs and you share the result. See [wholesaler vs. realtor vs. cash buyer](/wholesaler-vs-realtor-vs-cash-buyer/) for how those compare.

Run your own house through the numbers:

From the closing tableI'd rather show a seller my math than argue about a number. If the house is in good shape and you can wait, I'll tell you to list it, because you'll do better. If it needs real work, I'll show you the repair items, the comps and what's left. Then you can compare it with anyone else's offer, line by line. A buyer who won't explain their number is the one to worry about.

## Questions about low cash offers

**Q: Why are cash offers so low?**

Cash offers from investors are low because the price must leave room for repairs, months of holding costs, buying and selling costs and a profit that covers the risk. Many investors work backward from the after-repair value using a rule of thumb, such as 70% of that value minus repairs.

**Q: What is the 70% rule in real estate?**

The 70% rule is an investor rule of thumb: the maximum offer is 70% of the after-repair value minus the repair costs. The 30% held back covers holding costs, closing costs on both ends, the resale commission and profit. Investors adjust it to the market and the house.

**Q: How much below market value do cash buyers pay?**

There is no fixed discount. How far below market value a cash investor pays depends on the repairs, the holding time, the local market and the buyer's costs. A house needing major work gets a much bigger discount than one needing paint. Compare several written offers to see your market.

**Q: What is after-repair value (ARV)?**

After-repair value is what a house is expected to sell for once it has been fixed up to the standard of recent comparable sales nearby. It is not the house's value today as it is, and it is not the asking price of houses still for sale.

**Q: Is a lowball cash offer a scam?**

A low cash offer is not a scam by itself. It may simply reflect repairs and risk. Watch instead for offers that are high at first and cut after inspection, buyers who won't explain their numbers, upfront fees, or pressure to sign today. Those are the warning signs.

**Q: Should I counter a low cash offer?**

Yes, you can counter a low cash offer. Ask the buyer for their after-repair value, comparable sales and main repair items, then point to anything they got wrong. Competing written offers are your strongest argument. Many investors have some room, and some don't.

**Q: Will I get more if I fix the house first?**

You will usually keep more if you fix the house first and list it, provided you can pay for the repairs, manage them and wait several months. The gain is what an investor would earn for taking on that work and risk. If repairs uncover more, your gain shrinks.

**Q: Do wholesalers offer less than other cash buyers?**

A wholesaler's offer can be lower than a direct buyer's, because the wholesaler's fee must fit inside what the end buyer will pay. The end buyer pays the fee on top of your contract price. On a hard-to-sell house, a wholesaler's buyer network may still produce the best firm offer.

**Q: Should I sell an inherited house for cash?**

Selling an inherited house for cash can make sense if it needs work, the heirs live far away or want a quick, as-is sale. Get an independent value first, make sure the person signing has legal authority, and compare more than one offer. Selling cheap rarely saves tax, because the basis generally steps up.

**Q: Do I need probate before selling an inherited house in Connecticut?**

If the house was in the deceased owner's name alone, Connecticut generally requires a probate estate, because the small-estate affidavit cannot be used for solely owned real estate (CGS 45a-273). The executor or administrator can sell during probate with the court's approval (CGS 45a-164).

**Q: Do cash buyers pay closing costs?**

Cash buyers usually pay their own closing costs and often cover some of yours, but terms vary, so read the offer. In Connecticut, the seller normally pays the conveyance tax, which is 0.75% state plus 0.25% or 0.50% town on most homes, and their own attorney.

**Q: Why did my cash offer drop after the inspection?**

A cash offer can drop after inspection because the buyer found something they didn't price in, or because the first number was built to be renegotiated. Ask for the specific findings in writing. You can refuse the new price and let the contract end on its terms.
