What are Rent Comps?
Rent comps (rental comparables) are similar properties used to estimate the market rent for a subject property. Just as sale comps determine a property's market value, rent comps determine its rental income potential. Accurate rent comps are essential for calculating NOI, cap rate, cash-on-cash return, and DSCR on rental investments.
Good rent comps share key characteristics with the subject property: similar bedroom/bathroom count, comparable square footage (within 15-20%), similar age and condition, same neighborhood or school district, and similar amenities. The closer the match, the more reliable the rent estimate.
Finding rent comps
Active listings: Properties currently listed for rent on Zillow, Apartments.com, Facebook Marketplace, and Craigslist. These show what landlords are asking but not necessarily what tenants will pay. Overpriced listings sit vacant.
Recently leased: Properties that were listed and are now rented. This is the most accurate data because it reflects what tenants actually agreed to pay. Zillow and Apartments.com sometimes show recent lease data.
Property management companies: Local PMs know exactly what similar properties rent for because they manage them. They are the best source for hyperlocal rent data.
HUD Fair Market Rents: Area-wide averages by bedroom count, published annually. Useful for Section 8 analysis but too broad for property-specific estimates.
Rent comps in deal packages
Including 3-5 rent comps in your marketing package when selling to buy-and-hold investors demonstrates that the projected rental income is achievable. Show the comp address (or general location), beds/baths, rent amount, and any notable differences from the subject property. This builds credibility and helps buyers evaluate the deal quickly.
Deal Run's comp analysis tools include rental comparables alongside sale comps, giving you both ARV and rental income data in a single search.
