Estimates only. Assumptions are listed below, and you can change every input.

Every day a unit sits empty between tenants is rent you never get back. Owners tend to feel the big turnover bills, like paint and carpet, and overlook the quiet cost of the two extra weeks it took to inspect, schedule repairs, and get the listing live. Across a portfolio those days add up to a real line item, and most of them are caused by waiting rather than working.

The estimate converts your average monthly rent into a daily rate, multiplies it by the days each turnover stays vacant and by the number of turnovers you handle in a year, and then shows what changes if you hit a shorter target. It also expresses the loss as a share of your gross potential rent so you can compare it with your other vacancy numbers. Nothing is assumed about why the gap exists; the tool only prices the days.

How to use this tool

  1. Enter your unit count, average rent, and how many turnovers you handle in a typical year.
  2. Enter the current average number of days a unit stays vacant between tenants, counted from move-out to move-in.
  3. Set a realistic target and read the daily cost, the annual loss, and the rent you recover by closing the gap.

What the math assumes

  • Assumes a daily rent equal to the monthly rent times 12 divided by 365, so every calendar day is priced the same.
  • Assumes the same average rent and the same vacancy gap for every turnover in the year.
  • Assumes gross potential rent is all units fully rented at the average rent for 12 months, and counts only turnover vacancy against it.
  • Assumes a target longer than the current gap recovers nothing rather than showing a negative saving.
  • Assumes no change in make-ready costs, concessions, or rent between the current and target scenarios.

Frequently asked questions

How do I measure my current days vacant per turnover?

Take the move-out dates and the next move-in dates for your last several turnovers, subtract, and average the results. Move-out inspection reports with timestamps make this easy to pull.

Where does the turnover gap usually come from?

Common causes are waiting to schedule the move-out walkthrough, waiting on repair quotes, and delaying the listing until the unit is fully ready. Photo inspections done the day of move-out let you order repairs and list sooner.

Should I include units that did not turn over this year?

Yes, in the unit count, because it sets the gross potential rent used for the percentage. Only the turnovers figure should reflect units that actually changed tenants.
