How it works
Tenant turnover cost is everything consumed moving one household out and another in — make-ready work, re-keying, marketing, and the rent that stops arriving while the unit sits empty — and it is the expense line most rookie landlords pretend does not exist until the third vacate notice. Evictions multiply the pain: legal fees plus filing plus eight or more additional weeks of zero collection, routinely reaching five figures on top of the turnover itself. Neither cost arrives evenly, which is why annualizing them matters. This calculator multiplies your expected turnovers per year by the all-in per-turn cost, layers on probability-weighted eviction expense, and divides by twelve to produce a level monthly reserve per unit. At half a turnover annually on $1,650 rent, ordinary turns alone cost about $3,320; a 3% chance of eviction adds roughly $190 more of expected annual loss — about 18% of rent in total that must be survived, not merely hoped away. Screening reduces the odds; retention reduces the frequency; the reserve absorbs what both miss. Landlords who fund this line stop making panic decisions at renewal time, which is precisely when bad decisions are most expensive.Formula
Annual = turnovers × (make-ready + weekly rent × vacant weeks) + eviction odds × (legal + weekly rent × 8) | Monthly reserve = annual ÷ 12
Tips
- Renewal offers beat turnovers: keeping a good tenant is always cheaper than replacing one.
- Track actual make-ready invoices per unit; averages drift upward silently.
- List vacant units before the old tenant leaves — marketing during notice cuts empty weeks.
- Strong screening is the cheapest eviction prevention that exists; verify income and history.
- Fund the reserve per door and let it build; a portfolio's first eviction draws on every unit's pot.
