Fees question

[Deb Smith]

In my lease The section about all of the fees it states there's a $25 charge for all notices to be sent.

Here's a copy :

Additional Lease terms: (1) Late payment fee of 5% of the monthly rent becomes effective three (3) days after due date of rent. On the fourth (4) day, a three (3) day notice will be issued. ( $25 fee for delivery of every notice) After that expires, this lease will be turned over to my attorney for legal action. On the Fourth (4) day, a $10 daily charge will apply for everyday the rent is past due.

(2) Check return fee of $50.00

Would this misunderstood as a $25 just for late rent notices? I mean it as anything that has to do with them ae: non compliance letters, warning letter. 

NOT like me writing a letter changing my address, bank info, etc. 

Can I charge the $25 fee for sending a warning letter? (Multiple complaints from neighbors in a very short period of time) 

I'm new and trying to lean the best ways to word my leases. Is there anywhere on here with samples as I have 2 units coming up next month. I want iron clad leases. Well, as good as can be
