Renewals Start 90 Days Early: The Turnover Math

Every landlord learns the same expensive lesson eventually: the cheapest tenant to keep is the one already in the home. Turnover is the silent expense of rental property. When a tenant leaves, the owner pays for the same unit three times — in vacancy while it sits empty, in turn costs to clean, repair, and re-market it, and in the leasing effort to fill it again. A month of vacancy alone can erase an entire year of careful rent increases.

Which is why, in my own portfolio, the renewal process starts 90 days before the lease ends — not when the tenant gives notice, and not in the final month.

What 90 days buys

• Time to price honestly. A renewal offer built on a current rental analysis, not a guess. The tenant sees a number with homework behind it; the owner gets market rent without gambling on a vacancy.
• Time to negotiate. If the tenant is wavering, 90 days is enough time to find out why — and often the why is a fixable maintenance issue, not the rent.
• Time to pivot. If the tenant is leaving anyway, the unit can be marketed and shown while still occupied, shrinking the vacant gap between tenancies to days instead of months.

My leases ask tenants for their renewal decision 60 days out. The offer reaching them at 90 days means the conversation starts before the deadline pressure does — for both sides.

Retention is earned mid-lease, not at renewal time

An early offer only works if the tenant wants to stay. That's decided by how the home is cared for during the lease, not by the letter that arrives near the end of it. This month, for example, I directed my property manager to check in with my Kent tenants on how the home is working for them, and to get estimates for a full furnace service and carbon monoxide detectors — a 20-year-old furnace serviced before it fails in January is worth more to retention than any renewal discount.

The math, plainly

Compare two outcomes on the same unit. In the first, the tenant renews at a modest, market-supported increase: income continues without a gap, and the increase compounds at the next renewal. In the second, the tenant leaves over an issue nobody asked about: the owner absorbs vacancy, turn costs, and leasing effort, then re-rents — possibly to a less-proven tenant — at roughly the rent the first tenant would have happily paid.

My current Kent tenants signed a 12-month extension of their original lease. That signature cost one analysis, one offer letter, and a year of keeping the home in good order. It's the best-returning work in the whole portfolio.

Turnover will always happen — people move, jobs change. The manager's job is to make sure it never happens by surprise, by neglect, or by calendar. Ninety days is how.
