See your true vacancy rate, what each day of empty unit is costing you, and how you stack up against the US market - backed by Census and Zillow data. Built for landlords and investors who want to make pricing decisions based on real numbers, not guesswork.
Before buying or when reviewing your existing portfolio — your vacancy rate is the single most objective measure of how often the asset is actually producing rent. A property persistently above the local market average isn't pulling its weight, and our vacancy rate calculator surfaces that gap in seconds. Use it as a quick first-pass filter before doing deeper due diligence on a new investment.
For a property you already own, vacancy rate is one of the most actionable performance metrics. It directly affects your cash-on-cash return and your property's resale valuation. The calculator benchmarks your rate against state-level US Census data and your ZIP's typical rent, then tells you whether the most likely lever is pricing, listing quality, or operational turnaround time.
There's no universal "good" number - a useful benchmark is to aim to be meaningfully below your state's average . Typically 1-3 percentage points lower. The calculator above pulls state-level data live from the US Census Housing Vacancy Survey, so you can see exactly where your property stands.
All benchmark data comes from authoritative, free US public datasets including:
- The US Census Bureau Housing Vacancy Survey (HVS)
-Zillow Research's Observed Rent Index (ZORI)
- US Department of Education College Scorecard data
All datasets refresh automatically each quarter so you're always seeing current market conditions, not stale year-old numbers. Your own inputs (rent, vacancy days, ZIP, property type) are processed locally in your browser to calculate the results - they're not uploaded to our servers or used outside this tool.
