What happens when your rental sits empty

Your rental will sit empty at some point. When it does, the rent stops and the payment keeps running, and the gap comes out of your reserves until a new tenant moves in.

The fix is boring. Know what an empty month costs, set money aside before it happens, and buy in a way that keeps the empty stretch short.

This piece is for someone who hasn't bought yet. If you already own a rental and want to fill it faster, read how to reduce vacancy and increase rent.

What one empty month costs

Take a real listing: 2107 S Seale Rd in Phenix City, AL. It's priced at $230,000, with a rent estimate of $1,800 a month. With 20% down, the example interest-only payment is $997 at 6.5% (not a Lineage quote). Add $226 a month in taxes and $74 in insurance, and the total monthly payment is $1,297. The 6.5% rate and 20% down are the site's example terms. Some first-time buyers get them, and some pay a higher rate or put more down, depending on credit, experience, and the lender.

The swing is the full $1,800 of rent. Lineage's plan builder models each rental at about $295 a month in cash flow. The $503 above is before management, repairs, and vacancy. The $295 is after management, taxes, insurance, and maintenance, but it has no vacancy allowance, so it's the number an empty month comes out of. One empty month wipes out roughly six months of it. Two empty months wipe out the whole year's cash flow, and a little more.

Utilities, lawn care, cleaning, and a leasing fee to place the next tenant can also land on you while the property is empty, and none of them is in the payment.

Illustrative example. Actual returns vary based on market conditions, property performance, and financing terms.

How to budget for vacancy

Treat vacancy as a monthly expense. Decide how many weeks a year you expect the property to sit empty, turn that into lost rent, and divide by 12. Set that amount aside every month the rent comes in.

The right row depends on the local market and tenant. For context, the Census Bureau put the national rental vacancy rate at 7.6% in the third quarter of 2026, up from 7.3% in the second quarter. In the South, where the example property sits, it was 9.2%. Those numbers cover all rental housing, apartments included, so treat them as background. The vacancy that matters is on your street, and your property manager is the best source for how long similar rentals take to lease.

When you read a pro forma, find the vacancy line. If there isn't one, the cash flow is overstated. Our guide on how to read a pro forma walks through where it usually sits.

What reserves are for

Lineage recommends six months of the full monthly payment (mortgage, taxes, and insurance) in reserve, and your consultant confirms the lender's own minimum. On the Seale Rd example, that's 6 x $1,297, or $7,782.

With $7,782 set aside, you could cover six full months of the loan payment, taxes, and insurance with no rent at all. Utilities, upkeep, and the cost of placing a new tenant would come on top. The point is to avoid making a decision about the property because you're short on cash.

The reserves can sit in a cash or investment account, including a 401(k) or IRA, though some lenders count only part of a retirement balance. A retirement account may count with the lender, but reaching it before 59½ usually means income tax plus a 10% additional tax, so keep some cash you can reach for an actual vacancy. Your CPA can tell you what pulling from your accounts would cost.

When a vacancy dips into reserves, refill them from the next rent before you treat any cash flow as profit.

What shortens vacancy

You can't prevent vacancy. You can shorten it.

Price to the market. An empty week on an $1,800 rental costs about $415 in lost rent. Pricing $50 a month under the market costs $600 over a year, roughly the same as 10 empty days. Holding out for top dollar often loses more than it wins.

Have a manager in place. A property manager who already handles the property can list it, show it, and screen applicants the week it opens up. If you have to find a manager after the tenant gives notice, the clock is already running.

Start with a tenant. Under the Lineage Standard, the property comes with a tenant vetted by a licensed property manager, with a signed 12-month lease, before you close. Your first year starts occupied, with a lease that runs 12 months. A tenant can still break a lease or stop paying, so it lowers your first-year vacancy risk rather than removing it.

Plan the renewal early. The months before a lease ends are when you decide to renew, adjust the rent, or get ready to turn the property. Waiting until the tenant leaves adds empty weeks. Lease length matters too, and our post on month-to-month leases covers the tradeoffs.

What to ask before you buy

Bring these to any property you're considering:

1. Is there a tenant now? When does the lease end, and at what rent?
2. How long have comparable rentals nearby taken to lease? Ask the manager, not the listing.
3. What does the manager charge to place a new tenant, and is any fee due while the property is empty?
4. What vacancy does the pro forma assume? Does the cash flow still work if you double it?
5. Where will your six months of reserves sit, and how quickly can you reach them?
6. Who handles the renewal conversation, and how far ahead of the lease end does it start?

A deal that only works with zero vacancy doesn't work.

Taxes on a vacant rental

IRS Publication 527 says that while a rental is held out for rent, you may be able to deduct ordinary and necessary expenses for managing, conserving, or maintaining it. You can't deduct the rent you didn't collect. Your CPA confirms how this applies to your situation.

Two empty months cost $3,600 on this example, so have that money set aside before you need it. Build my plan to see the numbers on your budget, or talk to a consultant.
