NEW YORK NEEDS BETTER LAWS

Two years ago my family and I decided to look to purchase our first home . With our credit in dissarry we coundn't get a loan. We then came across a mobile home park that offered rent to own . They had this double wide available so my wife and I decided to look at it .
After looking at the home we knew it needed some work but we didnt think it was that bad. We put down the $2000 down payment and signed the contract.

When we looked at the the house it was summer time and all the windows where open. About two months after moving in with the windows shut we started to get on animal odor in the house. We pulled the panelling away from the wall and found urine stays halfway up the wall . To make things worse we had to completey gut my sons bedroom becouse of the odors. Both the bathrooms floors fell in and under the tubs and wall around are completely covered in mold. no floor under the washer and dryer.

With all this hidden stuff wrong with the house. We start to look at laws or something we can do to get out of our contract But have been unable to because we rent to own
and we are responable for all our repairs because we are purchasing and if we default we can be taking to court for the rest of whats owed Wat to do for my familys health and well being
