D F: It's tought to say right now what is available for Canadian investors. I did, however speak to a lender the other day that would entertain a 50% Loan to Value on a purchase.
Also, as far as purchasing REO's I have a lot of experience in them and here is what I can recommend from my purchases. Most of the better REO's are those that are listed by realtors. This means they have already been to the auction and did not get taken. Once a bank lists with a realtor, they are somewhat desparate to sell.
I work with an asset management company out of Florida and we have been buying foreclosures from 55k to 75k on homes built within the last 5 years.
My strategy is to buy and hold and my goal is to buy 2 homes per year over the next 10 years. I have already bought 5 of them and rent them for $800 per house. I get a small, but positive cash flow on 3 of them, and the other 2 I have 15 year mortgages on them and lose the positive cash that I have on the other 3 by paying the balance on the 2. I don't care about today's cash flow, I care about the future payoff in 10 years and speculated equity I will have at that point.
