Enter current rent and the increase amount (% or flat dollar). If your area has rent control, enter the cap — the calculator flags illegal increases. Pro Forma models a larger increase.

Rent increases should be communicated in writing per your state's notice requirements (typically 30–60 days). Many cities have rent control ordinances limiting annual increases. Always check local law before implementing a rent increase. The NOI impact section shows how rent increases directly increase property value.
