About RentReadyCheck
RentReadyCheck is a free rent calculator website that helps renters estimate apartment affordability, co-signer income, roommate income, move-in costs, and rent splits.
What the site helps with
The calculators help estimate rent affordability, co-signer income, roommate affordability, upfront move-in costs, and fair rent splits. A good place to begin is the rent affordability calculator. The site is focused on renters in the United States.
What the site does not do
RentReadyCheck does not provide financial, legal, or housing advice. It does not decide whether a landlord or property manager will accept an application.
Why the tools are estimates
Landlords and property managers can use different rules. Income is only one part of the picture, and individual circumstances matter.
Always confirm requirements
Before applying, ask the landlord or property manager which income rule, co-signer requirements, security deposit amount, and documents they require.
