Edit anything you like. The letter updates when you change the numbers above, unless you have edited it by hand.

How much is a reasonable increase?

There is no single right number. Many landlords look at what similar units nearby are renting for, weigh that against the cost of losing a good tenant and a vacant month, and raise rent by a few percent. Small, regular increases tend to go down better than one big jump after several years.

Check the rules before you send it

Some states and cities cap how much rent can rise in a year, and almost all of them require written notice a set number of days ahead, often 30 to 90. A fixed-term lease usually cannot change in the middle of the term unless it says so. Confirm your local rules, then use the letter as a starting draft.
