An empty month costs you the rent, plus the expenses that only exist because the house is empty, plus the turnover costs the vacancy triggered, while the mortgage, taxes and insurance that rent used to cover now come out of your own account. The rent is the biggest line, and it is rarely the whole bill.
Rather than quote you a figure, I want to give you a four-line formula so you can work out your own number, then show you how to turn it into a per-day cost. That per-day number is the most useful figure a rental owner can carry around, because almost every leasing decision comes down to it.
Two ways to count it, and which one to use when
Owners mix up two different numbers. The first is cash out of pocket: everything you will pay during the vacant month with no rent coming in. That includes the mortgage, taxes, insurance and HOA dues, which were always there but are now yours to fund, plus utilities, lawn care and the turnover costs. This is the number for your reserve.
The second is the true cost of the vacancy: what you lose compared with the house being occupied. The mortgage is paid either way, so it is not an extra cost of being empty. What is extra is the lost rent, the expenses that only exist while the house is empty, and the turnover costs. This is the number for decisions about price, concessions and speed.
What a vacant month really costs a rental owner does the full accounting line by line. Here I want to get you to a per-day figure quickly.
The four-line formula
- Line one, lost rent. Monthly rent divided by thirty gives your daily rent. Every vacant day costs this much, no exceptions.
- Line two, vacancy-only expenses. Utilities in your name so the house can be shown, lawn service, a vacancy check or two, higher insurance exposure. Divide by thirty for a daily figure.
- Line three, turnover costs. Make-ready work beyond what the deposit covers, photos, listing costs, the leasing fee. These happen once per turnover, however long the vacancy lasts.
- Line four, the time. Days from move-out to the next rent payment, including the make-ready, the marketing window and the gap between approval and move-in.
Your true cost of one vacancy is line three plus the sum of lines one and two multiplied by line four. Your per-day cost of each extra day empty is lines one and two together. Keep both. The first tells you what a turnover costs; the second tells you what one more day of waiting costs.
The costs owners leave out
Four items are missing from most owners' math. The leasing fee is a cost of vacancy, because it only exists because the tenant left; it belongs in line three. Your own hours belong there too if you are self-managing: the showings, the calls, the trips to let in a painter.
Insurance is the one that can hurt. Many landlord policies limit or exclude certain coverage once a home has been vacant beyond a stated period. Check your policy and ask your agent what that period is before a vacancy, not after a loss.
Taxes are the last. Rent you never received is not a deduction; it simply was not income. The expenses you paid during the vacancy generally remain deductible as they would in any other month. That is general information, not tax advice, so confirm the treatment with your CPA.
An illustrative example, worked per day
Take an illustrative example of a house that rents for $2,000. Line one is about $66 a day. Line two, with utilities and lawn care in the owner's name, is around $8 a day. So every extra day empty costs roughly $75, before counting anything that was paid once.
Line three in this example: make-ready beyond the deposit of $800, photos and listing of $200, and a leasing fee of $1,000. That is $2,000 of turnover cost that arrives whether the house is empty for ten days or forty. If line four comes to thirty days, the true cost of this vacancy is $2,000 plus thirty times $75, or about $4,250. Out of pocket, add the mortgage, taxes, insurance and HOA dues for the month on top.
Those are illustrative figures, not quotes. Yours will differ, and the rental turnover cost and timeline guide shows how to shorten line four, which is the only line you fully control.
How to use the per-day number
Once you know that an extra day costs about $75 in the example above, every leasing decision becomes a days question. A $50 price cut over a twelve-month lease costs $600, which is eight days. If the cut leases the house more than eight days sooner, it wins. A half-month credit is about thirteen days. Professional photos, a faster painter, self-guided showing access: each is worth doing if it saves more days than it costs.
The same number tells you when not to act. Dropping the price by a large amount to save three days is a loss. Holding out for an extra $100 a month that takes three more weeks to find is a loss. Owners who carry their per-day number make these calls in minutes, and rental pricing from leased comps, reviewed at agreed dates, keeps line four short in the first place.
The reserve side: what to have on hand
For budgeting, go back to the out-of-pocket number. Add the mortgage, taxes, insurance and HOA dues for one month to the vacancy-only expenses and the turnover costs, and that is roughly what one empty month draws from your account. Owners with a reserve that size do not make panicked pricing decisions, which is itself a saving; a hurried cut to end the pain usually costs more than the days it saves.
How much reserve to keep per rental covers where that money should sit and how large it should be across more than one house.

How Perpetual handles this
Perpetual Property Management manages line four. The make-ready list is written before the current tenant leaves and vendors are scheduled for the day after move-out, the house is photographed the day it is finished, and the listing goes live the next day, syndicated to the MLS and the major portals. The price comes from homes that actually leased in Keller, North Richland Hills and Fort Worth, with a review date agreed in advance so the house does not sit while everyone waits for a decision.
You see views, inquiries, showings and applications in the owner portal while the house is listed, and screening applies the same written criteria to every applicant so the lease is signed within days of the right application. Every fee, including the leasing fee that belongs in your line three, is listed in your written quote before you sign, so you can build your own per-day number from real figures. Perpetual is broker-owned and local, and the leasing process exists to shorten the one line of this formula you cannot control alone.
The takeaway: Work out your own per-day cost of vacancy with the four-line formula, then make every pricing and timing decision as a question of how many days it saves.
Questions owners ask
Is lost rent from a vacancy tax deductible?
No. Rent you never received was never income, so there is nothing to deduct. The expenses you paid during the vacant period, such as utilities, lawn care, repairs and management costs, generally remain deductible in the same way as in any other month. This is general information rather than tax advice, so confirm the treatment of your specific situation with a CPA.
Does landlord insurance still cover a vacant rental house?
Often only for a limited period. Many landlord policies restrict or exclude certain coverage once a home has been vacant beyond a stated number of days, and the definition of vacant varies by policy. Read your policy and ask your agent what the period is before a vacancy begins, and ask about a vacancy endorsement if a long gap is expected.
How do I reduce the cost of a vacancy between tenants?
Shorten the days. Start the make-ready list before the tenant leaves and book vendors for the day after move-out, photograph the house the day it is finished, price it from leased comps at the number you intend to lease at, make showings easy, and screen complete applications within a couple of business days. Each of those takes days off the timeline, and days are what the vacancy costs.
Should I count my mortgage as a cost of vacancy?
For your reserve, yes, because you will pay it from your own account that month. For deciding whether a price cut or a concession is worth it, no, because the mortgage is paid whether the house is empty or occupied. The decision number is the lost rent plus the expenses that only exist while the house is empty, worked out per day.
