About this report. Generated from your inputs and free public data sources (US Census Bureau Housing Vacancy Survey, Zillow Research). Not financial, legal, tax, or investment advice. All numbers depend on the inputs you provided and on third-party data that may be revised, become stale, or contain errors. Vacancy rate calculations are sensitive to how you count available vs off-market unit-days. Always do your own research and consult a qualified property manager, accountant, or real estate professional before acting on these figures. Landlord Studio accepts no liability for decisions made on the basis of this report.
Not financial, legal, tax, or investment advice. This tool provides general market context based on US Census Bureau and Zillow Research public data. Numbers depend on the inputs you provide and on third-party data that may be revised or become stale. Always do your own research and consult a qualified property manager, accountant, or real estate professional before making pricing or operational decisions. Vacancy rate methodology varies — landlords typically count units as “vacant” only when they are available for rent and being marketed, not units pulled off-market for renovation. Adjust your inputs accordingly.

What does the vacancy rate calculator do?

Spot underperforming investment properties

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.

Improve the properties you already own

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.

What is a good vacancy rate?

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.

Where does the calculator source its data from?

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.
