Should you sell your house or rent it out?

Somebody is relocating, or upsizing, or finally moving in together, and the question arrives in the same shape every time. We could just rent the old place out, right?

You could. Sometimes it's clearly the better call. But the conversation almost always starts with the monthly numbers and stops there, and the monthly numbers are the least important part of the decision.

The part nobody mentions is that a clock starts the day you move out.

Key takeaways

• The federal capital gains exclusion on a primary residence requires you to have lived in the home two of the last five years. Move out and rent it, and you have roughly three years before that exclusion is gone.
• The exclusion is up to $250,000 of gain for a single filer and $500,000 for a married couple filing jointly. On a house held a long time in this market, that is the largest number in the decision.
• Depreciation while it is a rental gets recaptured when you sell, whether or not you claimed it.
• Rent minus mortgage is not profit. Vacancy, turnover, maintenance, management and the tax bill all come out of that gap first.
• Becoming a landlord in California means AB 1482, deposit rules, notice periods and habitability obligations apply to you from day one, with no grace period for not knowing.
• The decision is rarely about whether you can rent it. It is about whether the return justifies what you give up to get it.

The clock nobody tells you about

Under Section 121 of the Internal Revenue Code, you can exclude gain on the sale of a primary residence if you owned and lived in it for at least two of the five years before the sale. Up to $250,000 of gain for a single filer, up to $500,000 for a married couple filing jointly.

Read that again with a move-out date in mind. The five-year window keeps sliding forward. Once you have been out for three years, you can no longer show two years of use inside it, and the exclusion is gone.

So renting it out is a decision with an expiration date attached. You have roughly three years to change your mind for free.

For somebody who bought in the Inland Empire a decade or more ago, that exclusion can be the single largest number in the whole analysis, larger than a few years of rental income, and larger than most people's instinct that holding real estate is always the right answer.

I'm not a CPA and this is the point where you talk to one. But you should walk into that conversation knowing the clock exists, because plenty of people find out about it in year four.

Depreciation is not optional

Once the house is a rental, the tax code treats it as a business asset and you depreciate it. That lowers your taxable rental income each year, which is good.

When you sell, that depreciation gets recaptured and taxed. Here is the part that catches people: recapture is calculated on the depreciation you were allowed to take, not on what you actually claimed. Skipping it on your return does not avoid it. It just means you paid full tax on the income and then get taxed again on the way out.

Again, CPA territory. But it belongs in the comparison, and it almost never is.

Rent minus mortgage is not profit

This is the number everybody runs first and it is the one most likely to be wrong.

Start with the rent. Then take out the mortgage, the property taxes, the insurance (which goes up when it becomes a rental, because a landlord policy is not a homeowner policy) and the HOA if there is one.

Then take out the things that don't bill monthly but happen anyway. Vacancy between tenants. The turn: paint, cleaning, whatever the last tenant broke. Maintenance, which on a house of any age is not zero and is not predictable. Management, if you aren't doing it yourself, and a hard look at whether you actually want the 10pm phone call if you are.

Then the tax on the net rental income.

What's left is the return. It can still be good. On a house with a lot of equity and a low payment, it often is. But it's a different number from the one people start with, and it should be the number you compare against what that equity would do somewhere else.

You become a landlord the day the tenant moves in

California does not have a category for people who didn't mean to be landlords. The obligations attach immediately.

Security deposits are capped and have to be returned on a deadline with an itemized statement. Notice to terminate a month-to-month tenancy runs 30 or 60 days depending on how long the tenant has been there. Habitability is not negotiable. There is an implied warranty, and a tenant has remedies if you don't meet it.

AB 1482 is the one that surprises people most. It caps annual rent increases and requires just cause to terminate a tenancy after a tenant has been in place long enough. Single-family homes owned by individuals are generally exempt — but the exemption requires that you give the tenant written notice of it. No notice, no exemption. That single sentence is the most expensive thing most accidental landlords never learn.

None of this is a reason not to rent it out. It's a reason to know what you're signing up for before the tenant signs anything.

When renting it out is genuinely the right call

Plenty of times. A few patterns I see repeatedly.

You have a payment that nobody could get today, the house rents for well over it, and you're prepared to hold for a long time. The spread is real and the exclusion was never going to be the bigger number.

You're relocating with a real chance of coming back. Renting for a year or two keeps the option open and keeps you inside the five-year window.

You want to be in the rental business, this is a reasonable first property, and you're treating it as the start of something rather than as avoidance of a decision.

The pattern I would push back on is the last one in disguise: keeping it because selling feels like losing, with no plan and no math. That is a decision made by not deciding, and the clock runs either way.

How to actually decide

Put both columns on one page.

On the sell side: the realistic sale price, the costs of selling, the loan payoff, and the tax outcome including whether the exclusion still applies. That's your net proceeds and what they could do elsewhere.

On the rent side: honest market rent, every holding cost including the ones that don't bill monthly, the tax on the income, and what you think the house does over your actual holding period. Then subtract the exclusion if the holding period runs past the three-year mark, because at that point you have spent it.

Twenty minutes with real numbers answers it, and the answer is frequently not the one the owner walked in with. Both directions.

Common questions

How long can I rent my house out before I lose the tax exclusion?

The test is two years of use within the five years before the sale, so moving out starts a window of roughly three years in which you can still sell and qualify. The exact arithmetic depends on your move-out date and your sale date, and there are exceptions for military and certain other circumstances. Confirm the specifics with a CPA before you rely on them.

Can I rent it out for a few years and then move back in to reset the clock?

Moving back in can re-establish use, but the rules on periods of non-qualified use mean the exclusion may be partial rather than full, and depreciation recapture does not go away. This is one of the most misunderstood areas in the whole analysis and it genuinely needs a tax professional, not a blog post.

Does it count as a rental if I let a family member live there?

For tax purposes, renting below market rate to a relative can change how the property is treated and what you can deduct. For landlord-tenant law, a person living there under an agreement is generally a tenant with a tenant's rights, relative or not. Both of those surprise people, and they surprise them late.

What does it cost to have someone else manage it?

Management is usually a percentage of collected rent, plus a leasing fee when a new tenant is placed, and the agreement will spell out what else is billable. Get the agreement and read what is included rather than comparing percentages, because the percentage is not where the differences are.

Run both columns before you decide

If you're weighing this, I'll put together both sides with your actual numbers — sale proceeds against holding returns, with the tax clock marked on it. Start with a [home valuation](/home-valuation) and we'll build the comparison from there.

If you're leaning toward keeping it and want to know what managing it actually involves, that's worth a conversation before the first tenant, not after. The [seller resources](/sellers) cover the other direction if you want both views.
