A cash offer that sits well below a likely list price looks like a bad deal. Often it is. Sometimes it is the better number once you subtract everything a traditional sale takes along the way.

Long Island sellers see this choice often. A local buyer like Suffolk County House Buyers buys houses, condos and multifamily homes in any condition and lets the seller pick the closing date. The question is not which price is higher. It is which path puts more money in your account, and how soon. This is general information, not financial, tax or legal advice.
Why Is the Sale Price the Wrong Number to Compare?
The sale price is a gross figure. You never receive it. What reaches you is the price minus selling costs, minus what the house cost you while it sat on the market.
People who track their net worth already know this trap. Home equity can make your net worth look bigger than the cash you could actually reach. A listing price works the same way. It is a hopeful estimate until a buyer closes.
So compare two net figures instead. Call them the listing net and the cash net.
Which Costs Come Out of a Traditional Sale?
A listed sale usually carries five kinds of cost. Some are fixed, and some depend on the house and the buyer:
- Commission. Agent pay is negotiable. Many sellers still budget about 5% of the price.
- Transfer tax. New York charges a state real estate transfer tax, usually paid by the seller.
- Attorney fees. New York sales usually involve a lawyer on each side.
- Pre-listing repairs. Paint, a roof patch or a new water heater to pass inspection.
- Inspection credits. Money a buyer asks for after their inspector finds problems.
Some of these also apply to a cash sale. Transfer tax and your own attorney do not vanish because the buyer pays cash. Ask any cash buyer, in writing, which closing costs it covers. Suffolk County House Buyers states that it charges no fees or commissions and covers most closing costs. Still, check the contract line by line.
What Does Each Month On the Market Cost?
Every month the house is unsold, you keep paying for it. These carrying costs are easy to forget because they arrive as normal bills.
Add up one month of these:
- Mortgage interest, not the full payment, since principal stays yours.
- Property tax, which on Long Island can run well into four figures a month.
- Homeowners insurance, often higher for a vacant house.
- Utilities, lawn care and snow removal.
- Any rent you pay elsewhere while you wait.
Then estimate how long a listing would take. Realtor.com publishes housing market data down to the ZIP code, including median days on market. Add time for the contract and the buyer’s mortgage approval. A home that sells in 60 days may still take 100 days to close.
If you set aside money for upkeep the way some hosts build a home maintenance fund from Airbnb income, you know how fast these bills add up.
What Does the Math Look Like On a Real Example?
Here is a hypothetical Suffolk County house with round numbers. Assume monthly carrying costs of $4,000.
| Line item | List with an agent | Cash sale |
|---|---|---|
| Price | $650,000 | $555,000 |
| Commission at 5% | -$32,500 | $0 |
| Pre-listing repairs | -$25,000 | $0 |
| Inspection credit | -$8,000 | $0 |
| Transfer tax and attorney | -$4,600 | Check contract |
| Carrying costs | -$20,000 (5 months) | -$4,000 (1 month) |
| Net before mortgage payoff | $559,900 | $551,000 |
In this sketch, listing wins by $8,900. That gap is about 1.4% of the list price.
Now change one assumption. If the listing takes nine months instead of five, carrying costs rise by $16,000. The cash sale now nets about $7,100 more. If the first buyer’s financing falls through, the gap grows again.
When Does the Lower Offer Come Out Ahead?
The cash offer tends to win in a few clear situations:
- The house needs major work you would have to fund before listing.
- Carrying costs are high, such as a vacant house with a large tax bill.
- You are behind on payments, so each month adds fees and risk.
- Your local market moves slowly, with long days on market.
- You hold two properties and need one sold before the next purchase.
The listing tends to win when the house is in good shape and the market is fast. In that case, repair and time costs stay small, and the full price gap stays with you.
How Do Taxes Change the Comparison?
Federal tax usually treats both paths the same way. The gain is the sale price minus your basis and selling costs. Say you owned and lived in the home for two of the last five years. Section 121 of the tax code then lets you exclude up to $250,000 of gain. Most married couples can exclude $500,000.
Timing is where speed can matter. Say you moved out and turned the house into a rental. The two-of-five-year window starts closing. A sale that closes in three weeks may keep the exclusion that a slow listing would lose. Run this with a tax professional before you choose.
Frequently Asked Questions
Is a Cash Offer Always Lower Than Market Value?
Usually, yes. A cash buyer takes on repairs, holding time and resale risk. The useful question is whether the discount is smaller than the costs you avoid.
Do You Still Pay Off Your Mortgage In a Cash Sale?
Yes. The lender is paid at closing from the sale money, the same as in a listed sale. You receive what is left after the payoff and any liens.
How Can You Check a Cash Offer Is Fair?
Ask for the offer in writing with all costs listed. Compare it to recent nearby sales. Then build your own listing net with the table above and see which number is larger.
Should Self-Employed Sellers Sell Before Buying Again?
Often it helps. Lenders review irregular income closely, and carrying two housing payments strains a variable budget. Selling first gives you a known cash figure to plan around.
