How it works

Why vacancy is the expense nobody budgets for

Repairs show up as invoices. Vacancy doesn't show up anywhere — the rent simply doesn't arrive. That makes it easy to underestimate, yet for many landlords a few weeks between tenants each year costs more than all their maintenance combined.

How lost rent is calculated

Lost rent = monthly rent × 12 ÷ 365 × vacant days

The vacancy rate is the vacant days divided by 365. Occupancy is the remainder. The recoverable amount applies the same daily rent to the days you think you could save.

How to reduce vacancy

Start marketing before the current tenant leaves, not after. Have the contract, inventory and deposit process ready so a good applicant can sign the same week. Schedule small repairs during the notice period. And keep good tenants: a renewal costs nothing, a turnover costs weeks.

Frequently asked questions

What is a normal vacancy rate?

For long-term lets in cities with steady demand, 3–8% a year (roughly 10–30 days) is typical. Seasonal or student lets, and properties that need work between tenants, run higher.

Should I count days spent on renovation as vacancy?

Yes, if the property could otherwise have been let. The rent doesn't arrive either way. Planned renovation is still vacancy — it is just vacancy you chose.

Does this include the cost of finding a tenant?

No. Agency fees, advertising and cleaning are extra costs on top of the lost rent. The calculator shows only the income you don't receive.

Why divide by 365 rather than by 30 days a month?

Because months have different lengths. Using the annual rent divided by 365 gives one daily rate that is the same all year, so 20 days in February costs the same as 20 days in July.

How do I know my real vacancy?

Add up the days each unit was empty over the last year. Llaverio does this automatically from your leases, and shows the occupancy of every property on the dashboard.
