Renting vs. Selling Your Home

The right question isn't "rent or mortgage?"

It's tempting to compare the rent you'd collect against the mortgage you'd pay and call it a day. That misses most of the picture. The real comparison is how much wealth each path leaves you with at the end of your holding period, after tax:

Our Sell vs Rent calculator runs both projections with your numbers and reports the difference — plus the rental's cash flow and cap rate.

First, pin down the rent

Every number below depends on one input: what your home would actually rent for. Don't guess — check current asking rents for comparable homes nearby using free tools like Zillow Rental Manager or Rentometer, and cross-check against HUD Fair Market Rents as a reference floor. A realistic rent — not a hopeful one — is what keeps the rest of this analysis honest.

A worked example

Say your home is worth $450,000, you owe $260,000 at a 5.5% rate, and it would rent for $2,600 a month. You paid $330,000 for it, you're married filing jointly, and you're weighing a 7-year hold. Here is how the two paths play out:

Renting edges ahead by about $11,000 over seven years — but look how close it is. The lost $40,000 tax exclusion nearly erased the advantage, and you fed the property $320 every month to get there. Sell within three years instead (keeping the exclusion), or change a single assumption, and the winner flips. That sensitivity is the whole point of running your own numbers.

The tax clock most people miss

This is the single most consequential factor, and it has a deadline. Under the Section 121 exclusion, if you owned and lived in the home at least 2 of the last 5 years, you can exclude up to $250,000 of gain if single, or $500,000 if married filing jointly — completely tax-free.

A second tax applies whenever you sell a former rental: the depreciation you take while renting (the building, over 27.5 years) is recaptured at up to 25%. Depreciation lowers your tax while you rent, then returns as a bill at sale. Note this is federal only — many states tax the gain and recapture separately.

The low-rate mortgage factor

If you locked a mortgage in the 2020–2021 era, your rate may be well under 4% — while new loans in mid-2026 run around 6.58% (Freddie Mac). That cheap, fixed debt is a real asset, and it only stays with this house. Renting the home keeps a tenant paying down a loan you could never replace at today's rates, which can tilt the math toward holding — the so-called "golden handcuffs." The flip side: that low rate can't move with you, so if selling would free the equity to buy your next home outright or with a smaller loan, the advantage narrows. Weigh the value of the cheap debt against what the trapped equity could otherwise do.

Can you keep it and still buy your next home?

If you're buying again, keeping the first home affects your next mortgage two ways:

• Your debt-to-income ratio. The old mortgage still counts against you — but lenders can offset it with the rental income. Under Fannie Mae's rules, generally only 75% of the gross rent is counted (the other 25% covers vacancy and maintenance), and you'll typically need a signed lease to use it.
• Your down payment. Selling frees the equity for a bigger down payment on the next home; renting leaves it locked in the first property, so you fund the next purchase from other savings.

If the departing home doesn't rent for enough to offset most of its mortgage, keeping it can shrink how much house you qualify for next. Check the effect with our affordability and DTI calculators.

The part nobody warns you about: being a landlord

A former home often makes a mediocre rental, because the mortgage was sized to a purchase price, not to what the rent can bear. Before you count on appreciation, pressure-test the operating math. Real rental costs include:

• Vacancy — budget ~5% of rent for empty months between tenants.
• Maintenance & repairs — roughly 1% of the home's value a year, more for older homes.
• Management — 8–10% of rent if you hire it out; your own time if you don't.
• Landlord insurance — usually pricier than a homeowners policy.
• The big one — a roof, an HVAC system, or a bad tenant can erase a year of profit.

Check the cap rate — a healthy US residential rental runs about 5–8%. If the numbers are thin, model it fully with the rental property ROI calculator before committing.

If you rent it out, here's what's actually involved

"Keep it as a rental" is a business decision, not a passive one. Before you commit, know the work behind it:

• Switch to landlord insurance. A standard homeowners policy generally won't cover a tenant-occupied home; you need a landlord (dwelling) policy, and many owners add an umbrella policy for liability.
• Learn your local landlord-tenant law. Security-deposit limits, notice periods, eviction rules, and habitability standards are set by state and city — and getting them wrong is expensive.
• Screen tenants properly. Credit and background checks, income verification, and references. One bad tenant can cost months of rent plus repairs.
• Decide self-manage vs. hire out. A manager takes 8–10% of rent but handles calls, repairs, and turnover — often worth it if you're moving out of the area.
• Keep a reserve. Set aside several months of expenses for vacancy and the inevitable big repair, separate from your own emergency fund.
• Track everything for taxes. Rental income, expenses, and depreciation all go on Schedule E — good records make tax time (and the eventual sale) far easier.

Distance amplifies all of this. An out-of-state "accidental landlord" who relocated for work almost always needs a property manager, which changes the cash-flow math — plug the management fee into the calculator to see the real number.

When each path wins

It's not only sell-now or rent-forever

Several middle paths can change the tax or timing math:

• Rent now, sell within the 3-year window. Capture a stretch of rental income or wait out a soft market, then sell while you still qualify for the Section 121 exclusion. The best of both — if you hold the deadline.
• 1031 exchange into another rental. If you keep it long enough to lose the exclusion, a 1031 like-kind exchange lets you defer the capital-gains tax and depreciation recapture by rolling the proceeds into another investment property. Strict rules apply: it must already be investment property (a primary home doesn't qualify until converted), you have 45 days to identify and 180 days to close the replacement, and you must use a qualified intermediary. It defers tax, it doesn't erase it.
• Move back in later. Re-occupying can help you re-qualify for the use test, but it won't undo depreciation recapture, and "nonqualified use" rules can still make part of the gain taxable. Fact-specific — get advice.
• Short- or mid-term rental. A furnished or seasonal rental can earn more per month than a standard lease, at the cost of far more management, higher turnover, and local rules that increasingly restrict short-term rentals.
• Sell to a tenant or family member. A rent-to-own arrangement or an installment sale can bridge timing and spread the gain — but these are contracts worth having a real-estate attorney draft.

A 6-point gut check before you decide

Run through these before you list the home or sign a lease. The more "no" answers, the more selling deserves a hard look:

1. Does it cash-flow? After every expense and the mortgage, is the monthly number positive — or at least one you can comfortably cover?
2. Can you sell within ~3 years if you want to keep the Section 121 tax exclusion?
3. Do you have a cash reserve for vacancy and a major repair, on top of your own emergency fund?
4. Are you fine being a landlord — tenants, late-night calls, and the paperwork — or paying someone who is?
5. Would the equity work harder elsewhere, diversified, than concentrated in this one property?
6. Is this a numbers decision or an emotional one? Wanting to keep a first home is valid — just name it, so it doesn't masquerade as a financial case.

If the answers are mostly "yes," renting is worth modeling seriously. If they're mixed, let the after-tax net-worth comparison break the tie.
