Tenant Improvement letter

[George Ramsay]

HI, 

Recently acquired a rental unit with a long term tenant. After a 60 day trial period of improvements and a rental increase i've agreed to allow the tenant to stay. The Tenant would like to replace the carpet which is perfectly fine with me. However I'd like to get something in writing that specifies the work, states that no credits will be given towards the security depots or rent, tenant is liable for any damages that occur, etc. I've been searching for a letter that would cover all the legal things like 'tenant improvements' but haven't come up with anything. So if anyone has one or can suggest where to get one i would appreciate at.

Thanks

George
