| Agent commissions | $27,500 |
Worked example
Selling at $550,000: gain is $550k − $300k basis − $30k improvements = $220,000. Married filers exclude $500,000 of gain — so capital gains tax = $0. Commissions: $27,500 (5%). Closing costs: $8,250 (1.5%). Mortgage payoff: $200,000. Net check: $314,250. Invested at 7% for 20 years: $1,213,000. The home sale windfall is a wealth-building pivot point.
Frequently asked questions
What is the home sale capital gains exclusion?
Section 121 of the tax code excludes up to $250,000 in capital gains for single filers and $500,000 for married filing jointly, provided you owned and used the home as your primary residence for at least 2 of the last 5 years. Gains above the exclusion are taxed at long-term capital gains rates (0%, 15%, or 20%).
What counts as a home improvement that raises my basis?
Permanent improvements that add value, prolong the home's life, or adapt it to new uses: additions, new roof, HVAC replacement, kitchen remodel, added bathroom, landscaping. Regular maintenance (painting, repairs) does not raise basis. Keep receipts — they reduce taxable gain when you sell.
Can I avoid taxes by rolling proceeds into a new home?
The old rollover provision was eliminated in 1997. Today, Section 121 is the only exclusion — you get $250K/$500K regardless of whether you buy a new home. Buying another house does not defer the gain.
What are typical seller closing costs?
Seller closing costs vary widely but typically run 1–3% of the sale price and include transfer taxes, title insurance (seller's policy), attorney fees, HOA transfer fees, and prorated property taxes. Buyer closing costs are separate and typically paid by the buyer.
