The real cost of a vacant unit (and how to shrink it)

Ask most property managers what a vacant unit costs and they'll say "a month's rent." It's much more than that. Vacancy is a stack of overlapping costs, and the part you can most easily control — how fast you turn inquiries into signed leases — is usually the one nobody measures.

The daily number

Start simple: a unit renting for $1,500/month costs about $50 a day while empty. That's pure lost rent you never recover — every day is gone for good. Across a portfolio with normal turnover, those days add up faster than owners realize.

What else is bleeding

• Make-ready and turn costs — cleaning, paint, repairs, listing fees, screening. A full turn commonly runs into the thousands per unit.
• Concessions — the longer a unit sits, the more likely you discount or offer a free week to close, permanently lowering the lease value.
• Marketing spend with nothing to show — you're paying for Zillow and Google leads that never convert because no one answered them fast enough.
• Owner trust — the hardest to price. Owners who watch units sit start shopping for a new manager.

The lever hiding in plain sight

Here's the part that matters: the U.S. average unit sits vacant around 41 days per turn — and a big chunk of that is self-inflicted. Leads answered hours late, follow-up that never happens, tours that no-show with no recovery. Shave even a few days off each turn and the math compounds hard.

A quick illustration for a 300-unit firm with 50% annual turnover — about 150 units to re-lease a year. Cut just 5 vacant days per turn and you recover roughly 150 × 5 × $50 ≈ $37,500 a year. That's not from more leads or a bigger budget — it's from working the leads you already get, faster.

The metrics that turn vacancy into a number you can manage

• Days-to-lease — the master metric. Multiply saved days by daily rent to get dollars.
• First-response time — the biggest driver of days-to-lease.
• Inquiry → tour → lease rates — where in the funnel you leak.
• Cost per qualified lead — so you know which sources actually earn their spend.

If you're not tracking days-to-lease against your response time, you're managing vacancy blind. The fastest way to find the leak is to measure what happens to a real inquiry today.
