Most sellers budget for the agent’s commission and stop there. But the real cost of selling a house usually runs higher, because a handful of expenses don’t show up until you’re already in the middle of the sale: repair requests after the inspection, credits to the buyer, months of mortgage payments on a house you’re trying to leave, and the cost of moving while you wait. None of these are secret. They’re just easy to overlook when you’re focused on the asking price.
The short answer
Beyond commissions and standard closing costs, the costs that most often surprise sellers are prep and repairs before listing, repair credits or concessions after the buyer’s inspection, holding costs (mortgage, taxes, insurance, utilities and upkeep while the house is on the market), moving and overlap costs, and in some cases taxes on the gain. You can avoid most surprises by estimating your net proceeds up front, not just your sale price.
What costs do sellers forget to budget for?
Here are the ones we see catch people off guard most often.
1. Getting the house ready to list
Fresh paint, deep cleaning, landscaping, small fixes, sometimes staging and professional photos. Each item is modest on its own, but together they add up, and you pay them before you know what the house will sell for. If you’re deciding whether bigger repairs are worth it, our guide on whether to fix up your house or sell as-is walks through which projects usually pay off and which don’t.
2. Repair requests and concessions after the inspection
This is the big one. Once you accept an offer, the buyer’s inspector goes through the house, and the buyer often comes back asking for repairs or a credit at closing. Buyers also ask sellers to cover part of their closing costs or a mortgage rate buydown. These concessions are common right now: according to Redfin, sellers gave concessions in 44.7% of U.S. home sales in August 2026, the highest August share in its data going back to 2020. Concessions don’t appear on a list of “closing costs,” but they come straight out of your proceeds.
3. Holding costs while the house is on the market
Every month the house doesn’t sell, you keep paying for it:
- Mortgage principal and interest
- Property taxes and homeowners insurance
- HOA dues, if you have them
- Utilities, lawn care, snow removal and routine upkeep
If the house is empty, check your insurance. Many standard homeowners policies limit coverage once a home has been vacant for a set period, and a vacant-home policy can cost more. Our page on selling a vacant house covers the other risks of an empty property.
4. Paying for two homes at once
If you’ve already bought or rented your next place, you may carry two housing payments until the sale closes. Some sellers also need a short-term rental or storage unit if their closing and move-in dates don’t line up. A buyer who lets you choose the closing date can take this cost off the table.
5. Moving costs
Movers, truck rental, packing supplies, storage and time off work. Long-distance moves cost far more than local ones, so get quotes early.
6. Deals that fall through
If a buyer’s financing or appraisal falls short, the deal can collapse weeks into the process. You lose that time, keep paying holding costs, and often have to relist. An appraisal that comes in below the contract price can also lead to a renegotiation, which usually means a lower price.
7. Taxes on the gain
Many sellers of a primary home owe nothing. The IRS lets you exclude up to $250,000 of gain ($500,000 for most married couples filing jointly) if you owned and lived in the home for at least two of the five years before the sale. Gains above that, or the sale of a rental or inherited property, can be taxable. Selling expenses like commissions generally reduce your taxable gain. See IRS Publication 523 for the details.
How much do hidden costs add up to?
It depends heavily on the house, the market and how long the sale takes. A house in good shape that sells quickly might have few extra costs beyond commissions and closing costs. A house that needs work and sits for several months can lose a meaningful share of its sale price to repairs, concessions and carrying costs. That’s why it pays to run your own numbers instead of relying on a rule of thumb.
| Cost | When it hits | How to reduce it |
|---|---|---|
| Prep and repairs | Before listing | Fix only what buyers will pay for, or sell as-is |
| Inspection credits and concessions | After you accept an offer | Get a pre-listing inspection, or sell to a buyer who doesn’t ask for repairs |
| Holding costs | Every month until closing | Price realistically and shorten the timeline |
| Overlap and moving | Around closing | Choose a closing date that fits your move |
| Failed deals | Mid-sale | Favor buyers with proof of funds or strong financing |
| Taxes on the gain | At tax time | Check the home sale exclusion and talk to a tax pro |
How do I estimate what I’ll actually walk away with?
Start with a realistic sale price, then subtract:
- Your mortgage payoff and any liens
- Agent commissions, if you list
- Your share of closing costs, title fees and any transfer taxes (our guide on who pays closing costs breaks these down)
- Prep and repair costs before listing
- A realistic allowance for inspection credits and concessions
- Holding costs times the number of months you expect the sale to take
- Moving and overlap costs
The result is your net. That’s the number to compare when you weigh different ways to sell.
Is listing with an agent still the better choice?
Often, yes. If your house is in good condition, you have time, and your market is moving, listing will usually get you the highest price, even after the costs above. A good agent can also help you avoid some of them. Where a cash sale tends to make more sense is when the house needs significant work, you need to move quickly, or carrying the house for months would be a strain. Our cash buyer vs. realtor comparison shows how to line the two options up side by side.
How a cash sale changes the math
With BAM, most of the costs on this list don’t apply. We buy houses as-is, so there are no repairs, inspection credits or staging. There are no commissions or fees, and we pay all of the closing costs. There’s no lender, so there’s no appraisal or financing to fall through. And you pick the closing date, as soon as 2–3 weeks or on your own timeline, which keeps holding and overlap costs down. You can see each step on our how it works page, or read more about selling your house as-is.
We’ve been doing this for more than 20 years and have bought over 500 houses. If you’d like to compare your numbers, get a free cash offer or call us at (312) 818-3954. We’ll send a fair offer within 24 hours and show you the math behind it, so you can decide which option leaves more in your pocket.
Costs, taxes and customs vary by state and situation. This is general information, not legal or tax advice, so check with a real estate attorney or tax professional about your sale.
