I live in Canada. I bought a home several years ago and now due to issues with the structure of the home, I may have to walk away from the home because I am financially unable to make all necessary repairs to it. What can I do and what are the consequences of such action?
If the bank will help me I can get the repairs done and keep my home.
If they won't I feel the problem may get worse.
It comes it may come down to the issue if the bank see's helping me out is a good or bad investment.

now because f the struction of the home, why do you think the bank will want it ?

You need to go into the bank and see if they will accept it back for the deed ( assuming you don't have a second mortgage on it)

If the home is valued ( with all of the issues) for a lot more than you owe, they may take it back, but the first step is to talk to the lender.

The US has something called a Deed in Lieu of Foreclosure. I don't know if Canada has something similar. Talk to your Lender to find out what options are available for surrendering your property.
