How to use rent PSF
Annual rent per sf: $19.86. PSF is the standard normalization for comparing rents across units of different sizes — especially for multifamily, mixed-use, and commercial space.
PSF varies non-linearly: tiny units rent at higher PSF (lots of shared overhead per sf), large units at lower PSF. Compare to similar-size comps when possible. Adjust for amenities, condition, and location quality.
How to Use
- Enter your subject property's monthly rent and square footage.
- Enter rent and square footage for up to 3 comparable rentals (similar location, condition, age).
- Read your subject's PSF and the comp average.
- Use the market rent estimate (subject sf × comp average PSF) to decide if you can raise rent or if a vacancy is priced too high.
Frequently Asked Questions
Why use rent per square foot?
PSF normalizes rent across units of different sizes. A 900 sf at $1,800 ($2.00/sf) and 1,500 sf at $2,800 ($1.87/sf) are roughly similar value per square foot — useful for spotting overpriced or underpriced listings.
Why does PSF vary by size?
Small units have higher PSF because shared overhead (kitchen, bathroom, mechanicals) gets divided across fewer sf. Larger units price at lower PSF as the extra space is mostly bedrooms or living. Always compare to similar-size comps.
What about amenities and condition?
PSF doesn't capture them. A 1,200 sf renovated unit and a 1,200 sf dated unit at the same PSF are not equal value. Adjust judgmentally or pick comps with similar finish level.
Is PSF used for short-term rentals?
Less commonly. STR pricing is driven by nightly demand, occupancy, and amenities more than size. PSF is a long-term-rental and commercial benchmark; use STR comps and ADR/RevPAR for short-term properties.
