Agree with what Sherilnn is saying. Usually we do an inspection when the tenant moves out, and if we notice the damage before hand, we would let them know that it's either they fix it themselves or we'll ask someone to fix it and the cost will come out from the deposit.
Depending on how well...
Usually you want to do a RRSP mortgage arms-length, meaning someone who's not in your family. If you want to go non-arms-length, you would have some limitation and you would need to pay market interest rate.
We do RRSP mortgage on other people's property, and others do for our properties.
