Mobile home lot rent increase calculator
For mobile home park residents: enter your current and proposed lot rent plus the notice dates to see the increase amount and how many days of notice you got.
Published May 31, 2026
This tool takes a few generic numbers and dates and tells you the size of a proposed lot rent change and how many days of notice it gives. It is general information — it does not decide whether your specific increase is legal, and it does not read or analyze any notice or lease.
How this calculator works
It subtracts your current rent from the proposed rent to show the dollar and percentage change, and it counts the calendar days between the date you received notice and the date the new rent takes effect. States set their own required notice periods for lot rent increases — some require 90 days, others differ — so the day count is meant to be compared against your own state's rule, which you can find in that state's lot rent guide.
What this calculator doesn't do
- It does not analyze your lease, notice, or any other document.
- It does not tell you whether your increase is legal or whether the notice was valid.
- It does not account for exceptions, mediation rights, or local rules.
- It does not provide legal advice or guarantee any outcome.
For your specific situation, consider consulting a licensed attorney in your state.
The proposed change is an increase of $75 (+12.5%).
Enter both the notice date and the effective date to count the days of notice given.
States set their own required notice periods for lot rent increases — for example, some require 90 days. This tool only counts the days between the two dates you entered; it does not decide whether your specific increase is legal. For your state's required notice period and for your specific situation, see your state's lot rent guide and consider consulting a licensed attorney in your state.
