Home Sale Costs

Home sale costs are the total expenses that reduce what a seller keeps from selling a home. They fall into a few categories: real estate agent commissions, seller-paid closing costs and transfer taxes, repairs and buyer concessions negotiated during the sale, the payoff of any remaining mortgage balance, and federal capital gains tax on profit that exceeds the home-sale exclusion. This page is the seller-side aggregator that lists the categories and how they fit together; the mechanics of each, commission structure, the gain exclusion, capital gains tax, and buyer-side closing costs, are covered on their own pages.

Commission is normally the biggest line, and how it works changed in 2024. Under the National Association of Realtors antitrust settlement, whose practice changes took effect August 17, 2024 and remain in force, a listing broker can no longer advertise buyer-agent compensation on the multiple listing service, and buyers must sign written agreements with their own agents setting that agent's pay. The practical effect is that commissions are openly negotiable and no longer default to a fixed total split evenly between the two sides. A seller may still choose to offer to cover some or all of the buyer's agent compensation as a concession, but it is a negotiated term, not an automatic one. Commission mechanics belong to the real estate agent commission page; the point here is that the number is a variable the seller can influence. Closing costs on the seller's side are the next category and vary sharply by location. They can include title insurance for the owner or lender, escrow or settlement fees, a real estate transfer tax or documentary stamp, recording fees, attorney fees in states that require them, and prorated property taxes and any homeowners association dues up to the closing date. Repairs demanded after inspection and closing-cost concessions to the buyer also reduce net proceeds even though they are not paid as separate invoices. Two items surprise sellers because they are not fees at all. The first is the mortgage payoff: the outstanding loan balance, plus any prepayment interest, is deducted from the proceeds at closing, so a seller with substantial equity nets far less than the sale price. The second is tax. Under Internal Revenue Code section 121, a seller who owned and used the home as a principal residence for at least two of the prior five years can exclude up to $250,000 of gain, or $500,000 for a married couple filing jointly, from federal income tax. That exclusion is a fixed statutory amount; it is not indexed to inflation and has not changed since it was enacted in 1997. Gain above the exclusion is taxed as a capital gain. Only the profit is taxed, not the sale price, and the profit is measured against the home's adjusted basis, which includes the original price plus qualifying improvements.

Netting out a sale works in layers. Start with the sale price. Subtract the negotiated real estate commission. Subtract seller-paid closing costs and transfer taxes. Subtract any repairs or concessions given to the buyer. Subtract the mortgage payoff. What remains is the cash proceeds. Separately, determine the taxable gain and whether the section 121 exclusion covers it. A hypothetical example ties it together. Suppose Nadia sells for $600,000 and has agreed to a total commission of 5 percent, or $30,000, negotiated with her agents. Seller closing costs and transfer taxes come to $9,000, and she gives the buyer a $5,000 repair concession. Her remaining mortgage balance is $250,000. Her cash proceeds are $600,000 minus $30,000 minus $9,000 minus $5,000 minus $250,000, which is $306,000. For tax, suppose Nadia bought the home years ago for $350,000 and made $50,000 of qualifying improvements, so her adjusted basis is $400,000 and her gain is $600,000 minus $400,000, or $200,000. Because she is single and qualifies, the section 121 exclusion of up to $250,000 covers the entire $200,000 gain, so she owes no federal capital gains tax on the sale. Had her gain been $300,000, the $50,000 above the exclusion would have been taxed as a capital gain.

Pros

• Estimating all the costs up front tells a seller their true net proceeds rather than a misleading sale price.
• Since 2024, commission is openly negotiable, giving sellers more room to reduce the largest line item.
• The section 121 exclusion shields a large amount of gain from tax for most homeowners selling a primary residence.

Cons

• The costs are substantial in total, with commission usually the largest single item and seller-paid closing costs adding meaningfully on top.
• Many costs, especially transfer taxes and title fees, vary by state and are hard to predict without local figures.
• Gain above the exclusion, or a sale that fails the ownership-and-use test, can create an unexpected capital gains tax bill.
