Listen, I love dealing the drug OPM, opium! Other peoples money! You should high on other peoples money asap. .....lol ....but seriously here's what I'd do if I were you.
1) Find a lender that loans based on whats known as "Stated Income". So you call around to some mortgage brokers. Tell them you have no money, but that you're trying to find a lender that offers mortgages based on stated income. Or do a search on the net to find one of these lenders. Typically these lenders are out there to aid small business owners to get mortgages. However, they will lend to just about anyone. And there's tons of these lenders out there. Typically they ask you to be able to put down 15% on a purchase.
2) Next you ask them if the 15% can be in the form of a VTB or second mortgage. If they don't care, then you start making offers. The offer would look like this:
85% First mortgage
15% VTB (second mortgage)
3) Make 100 offers. Out of those you're bound to buy at least 1 house with no money down. Even try to get the lender to carry more than 15% if possible. So perhaps carry like 25%. That way you'll get the house and walk away from the deal with cash in your pocket. My friend has done this.
4) Try to find a house that you could convert each room into a mini bachelor suite. So what you'd do is convert each room into a miniture suite with a mini fridge, and just the basics. And then have them share the main kitchen, and share the bathroom. Turn it into sort of a dorm room or boarding house so to speak. Like really pack them in there!!!
that's one way to get started.
