Dear Tenant Mr. Aaron Powell,

Sorry me about that. I can put your rent tax from $1500 to $1000 for six months but you have assigned the contract and now, the house is your responsibility. 

The environment question is a future thing to think and we aren't in the '60's to let it pass, so I will buy a new heat system, but the installation is by yourself.

Anything else, you can contact me at the phone number and address that you already now.

Your comprehension, 

Mr. Leonardo
