Hello, I received your email in regards to your interest in my 4 BR family home. 
i am very interested in renting your home. the only thing i would like to ask is if you could come down $2700? i would be willing to take care of all outside landlord related maintenance like the lawn in such for you
Hmm, I was expecting to remain at $3200 firm BUT if you would do all the yard maintenance and gardening, I have lots of rose bushes that need care,  I think I can come down on the price. I will expect you to sign a 2 year lease for $2700 though. 
i think a two year lease for $2700 sounds completely fair.
