Vacancy Cost Calculator: What an Empty Rental Really Costs You

An empty rental doesn't pause your bills. The mortgage, taxes, insurance, and lawn care keep running whether or not rent is coming in, which means every vacant month costs you the full rent you didn't collect plus everything you paid to keep the lights on. This calculator adds up your real monthly vacancy cost, then lets you test how different rent prices change how long your home sits.

How to Use the Vacancy Cost Calculator on Our Website: Step-by-Step Guide for Landlords and Property Owners

  1. Enter Your Property Details
    Fill in the input fields with your specific rental property information:

    •Monthly Rent: Enter the high and low rent values.

    •Mortgage Payment: Input your monthly mortgage cost.

    •Property Taxes: Include your monthly property tax expense. If you do not know your property tax amount, you can check it on the Bexar County website. The values are updated quarterly. If you have gone through a recent appeal, the amount might not yet reflect that change.

    •Insurance Costs: Enter your monthly property insurance premium.

    •Utilities: Include utility costs paid by you (water, electricity, gas, internet).

    •Monthly HOA Fees: Input HOA charges if applicable.

    •Maintenance Costs: Enter expected monthly maintenance expenses.

  2. Adjust for Your Vacancy Expectations
    Average Days on Market for properties priced at market rate for the month of September 2025 was 50. The higher the rent is above market rate, the longer the property will stay on the market. Properties listed just below market rate (even as little as $50-$100), will move much more quickly.

  3. Review the Calculated Vacancy Costs
    The calculator will immediately display the total costs incurred per month due to vacancy, including a breakdown of each expense category. Review this information to understand your ongoing expenses during periods when the property is unoccupied.

  4. Compare Different Pricing Strategies
    Use the comparison features to see how adjusting your rent price affects vacancy duration and costs. For example, lowering rent slightly may lead to faster occupancy and reduce overall vacancy expenses, helping you maximize profitability.

  5. Make data-driven rental pricing decisions
    Utilize the insights from the calculator to decide whether to lower your rent slightly to fill the property faster or maintain a higher rent and risk a longer vacancy. This analysis helps you balance rent rates and vacancy durations, saving money over time.

  6. Repeat with Different Scenarios
    Test various rent levels or expense assumptions to see how they influence your vacancy costs. This flexibility enables you to identify the most profitable rental strategy tailored to your property.

Deciding Something Bigger Than Price?

If the numbers here have you wondering whether keeping the property makes sense at all, our Rent vs Sell Calculator compares holding your home as a rental against selling it today, using your actual payoff and expenses.

Why Overpricing Is the Most Expensive Mistake in a Soft Market

Here's the math most owners never run. Say your home should lease at $1,900 based on what similar homes actually rented for. Listing at $2,000 feels like a $100 a month win. But if that price adds just two extra months of vacancy, you've lost about $3,800 in rent plus two months of carrying costs, and it would take over three years of the higher rent to earn that back.

Properties priced at market rate in San Antonio averaged about 50 days on market [UPDATE MONTHLY FROM MARKET REPORT]. The higher the rent sits above market, the longer that stretches. Homes listed even slightly below market, sometimes by as little as $50 to $100, move much faster. You can see current days on market and rent trends in our San Antonio Rental Market Report.

FAQ

  • The full rent you're not collecting, plus your mortgage, taxes, insurance, utilities, and upkeep. For a typical San Antonio home, that combined figure often runs well above the rent itself, which is why one vacant month can erase a year of gains from a higher asking price.

  • It depends on price, condition, and season. Homes priced at market have recently averaged around 50 days on market, and overpriced homes sit longer. Our monthly market report tracks the current number.

  • Usually, yes, and the calculator above will show you why. A small price cut early almost always costs less than another month of vacancy. Cuts made in week two work harder than cuts made in month two.
