A starter guide for older homeowners weighing a move to a smaller place: real selling and buying costs, the capital gains exclusion, and how downsizing compares with borrowing on the home you own now.
Selling the house you have lived in for decades can free up real money for retirement, but the cash you keep is always smaller than the number on the contract. Selling costs, buying costs and taxes all take a share, so downsizing rewards homeowners who plan ahead. This guide walks through what a move actually costs, how the federal home sale tax exclusion works, and how selling compares with borrowing against the equity you already have.
Why Homeowners Downsize and When It Makes Sense
For many older Americans, much of their net worth is tied up in the home, and that equity cannot improve daily life unless you sell the house or borrow against it. The Consumer Financial Protection Bureau (CFPB) counts downsizing among the alternatives to a reverse mortgage, alongside waiting before borrowing, taking a second loan secured by the house, refinancing and cutting expenses.
A move can make sense when the house no longer fits: rooms sit empty, upkeep eats into the budget, or the equity would do more good as savings you can actually spend. Stairs, yard work and distance from family weigh on the decision too. This guide sticks to the financial side, because that is where the surprises tend to hide.
Tallying the Real Costs of Selling and Buying Again
A move is really two transactions, and each carries its own price tag.
On the selling side, expect agent commissions, title and settlement charges, and any repairs needed to put the home on the market. On the buying side, a smaller home can still bring a down payment, lender fees and closing costs if you finance it, plus moving expenses either way. Closing costs are the fees due at settlement, covering items such as title work, appraisals and lender charges, and they generally run into the thousands of dollars. How much cash you need to close on a house walks through that total, and the Loan Estimate a lender provides lets you compare fees line by line.
The number that matters is your net proceeds: the sale price, minus your remaining mortgage balance, minus the costs of selling, then minus what it takes to close on the next place. That figure, not the sale price, is what you actually have to work with.
The Capital Gains Exclusion When You Sell Your Main Home
A capital gain is the profit on a sale: what you sell the home for, minus what you paid for it plus certain qualifying costs. Federal law, Section 121 of the Internal Revenue Code, lets you exclude a large share of that gain from income when you sell your main home. The cap is up to $250,000 of gain for a single filer, or up to $500,000 on a joint return with a spouse.
To qualify, you must meet two tests during the five-year period ending on the sale date:
- Ownership test: you, or your spouse on a joint return, owned the home for at least 24 months.
- Use test: you lived in it as your main home for at least 24 months. On a joint return, both spouses must meet this test individually.
Three more rules catch sellers off guard. You generally cannot claim the exclusion if you claimed it on another home sold within the previous two years. If you rented the home at some point, gain equal to depreciation you claimed or were entitled to claim for periods after May 6, 1997 cannot be excluded. And a loss on the sale of a main home is not deductible.
A simple illustration: you bought your home for $200,000 and sell it for $430,000, a gain of $230,000. As a single filer who meets both tests, you could exclude the entire gain from income.
Reporting depends on paperwork. If you exclude all the gain and no Form 1099-S was issued, the IRS says you do not need to report the sale. If you receive Form 1099-S, Proceeds From Real Estate Transactions, you must report the sale even when the whole gain is excludable. Publication 523, Selling Your Home, holds the complete rules and worksheets.
Worth knowing
Before listing the home, check the two-year clock. If you claimed the exclusion on another home sold within the past two years, you generally cannot use it on this sale.
Smaller Home, Smaller Bills: What Actually Shrinks
Monthly costs usually fall when the next home is smaller and less expensive. Utilities, routine maintenance and repairs tend to track the size and age of a property, so a newer, smaller place often costs less to run. Property taxes may drop as well, though that depends on how the new home is assessed in its own jurisdiction.
Some costs do not shrink automatically. Homeowners association dues can exceed the upkeep they replace, insurance pricing varies by location, and taxes in a new county or state can surprise movers. Before you buy, ask to see the seller’s recent utility bills and tax statements, read the HOA fee schedule, and confirm with local officials how reassessment works, since rules vary by state.
Downsizing vs. Tapping Your Equity Instead
Staying put and borrowing is the other path.
The reverse mortgage most homeowners encounter is the Home Equity Conversion Mortgage (HECM), and it is limited to people aged 62 and older. You make no monthly mortgage payments. Instead, interest and charges accrue onto what you owe month after month, so the balance climbs while your equity shrinks, and the loan is repaid when you die, sell the home or move out, usually through a sale. The Federal Trade Commission cautions that the fees and interest on these loans can total more than other ways of borrowing against a house, and that the growing balance can consume most or even all of your equity, leaving you short if you later want a smaller place. Qualifying also requires a counseling session with a HUD-approved agency. Does a reverse mortgage really take your home? explains the mechanics in more detail.
A fixed home equity loan or a revolving credit line secured by the house (a HELOC) is often less costly borrowing, according to the CFPB, but it carries its own risks: monthly payments are usually required, and qualifying depends on your income and credit.
| Option | Payments while you stay | How it is settled |
|---|---|---|
| Sell and downsize | None unless you finance the new home | Selling costs and any mortgage payoff come out of the proceeds |
| Home equity loan or HELOC | Usually required | Repaid in monthly installments over the loan term |
| Reverse mortgage (HECM) | No monthly mortgage payments | Balance plus interest and fees comes due when you sell, move out or die |
Timing the Move Around Mortgage Payoff and Retirement Income
If you still owe on the current mortgage, the payoff comes out of the sale proceeds at closing, so you do not need cash on hand for it. Paying cash from the proceeds on the next home keeps future costs low. If you finance instead, the CFPB cautions that a new 30-year mortgage taken close to retirement can become a hardship later, and suggests a shorter term such as 10 or 15 years. Depending on rates, refinancing the mortgage you keep rather than moving could also lower payments, but watch the repayment length for the same reason.
One more tax wrinkle: if the sale brings in less than you owe and the lender forgives the difference, that canceled debt is generally reported as income. The IRS notes an exception for qualified principal residence debt discharged before January 1, 2026, or covered by a written agreement for the forgiveness in place before that date. If your sale might come up short, talk with a tax professional before you sign.
A sensible first step: gather your current mortgage statement, a realistic estimate of your home’s value and your latest property tax bill. With those three documents, a conversation with a HUD-approved housing counselor can help you compare selling, borrowing and staying.

The short version
- Selling your main home can exclude up to $250,000 of gain from federal income tax, or up to $500,000 on a joint return, if you meet the ownership and use tests.
- You must have owned and lived in the home as your main home for at least two of the five years before the sale, and you can claim the exclusion only once every two years.
- Downsizing means paying selling costs on one home and buying costs on another, so the cash you walk away with is less than the sale price.
- A reverse mortgage requires no monthly payments, but interest and fees grow the balance, and the loan comes due when you sell, move out or die.
- A fixed home equity loan or a HELOC is often cheaper borrowing, but it requires monthly payments and qualifying based on your income and credit.
Readers also ask
Do I pay tax on the whole sale price when I downsize?
No. The exclusion applies to your gain, which is the selling price minus what you paid for the home plus certain qualifying costs. If your gain is within the $250,000 or $500,000 limit and you meet the tests, none of it is included in your federal income.
Do I have to report the sale if my gain is fully excluded?
Usually not. If you exclude all the gain and no Form 1099-S was issued, the IRS says you do not need to report the sale. You must report it if you receive a Form 1099-S or cannot exclude all the gain.
Is a reverse mortgage a simpler way to get cash instead of moving?
It avoids a move, but the FTC and CFPB caution that fees and interest can make it a costly form of borrowing and can drain equity you might want later. The balance is repaid when you sell, move out or die.
What happens to my current mortgage when I sell?
The payoff comes out of your sale proceeds automatically at closing. If the sale does not cover the balance and the lender forgives the difference, that canceled debt is generally reported as income unless an exception applies.
