Good advice, it's definitely easier to get them out when they aren't in a lease. Here's the letter I was going to hand-deliver or mail to them this week:
Dear [Tenant],
Due to the increased cost of the mortgage, property taxes, insurance, and maintenance, an increase in your monthly rent will take effect March 1, 2023. Sub-meters will also be added to the water lines and you will be responsible for the water bill for Unit A beginning March 1, 2023. This letter serves as official notice for the increase in rent and responsibility of the water bill for [Property Address].
Current Rent: $425.00
New Rent Rate as of 3/1/2023: $550.00
If you would like to sign a new lease, please provide me with your email address and I will send you an application to apply. Everyone over the age of 18 would need to fill out the application. If the application is not returned by January 15, 2023 it will be considered as your intent to move by March 1, 2023. If you do not wish to pay the increased rent you may decide to seek other housing. If you intend to vacate, please provide a 30-day written notice of your intent to move. If you have any questions or concerns, please text or call me at [phone number].
By signing below, you acknowledge that you received this notice and agree to renew at $550.00/month and be responsible for the water bill for Unit A as stated above or you will provide a 30 day move-out notice prior to March 1, 2023.
Sincerely,
Andrew
