Yes, real estate is hot around Boston. If you can't beat the market, maybe try to find them before they get to the market.
I just listened to the BP podcast show 171, where the guest describes a great way for driving for dollars. I think that is a great start. I currently live in Watertown close to the Belmont border. As I run around and do errands, there's definitely some possibly distressed houses that would be worth a $0.50 postcard or letter. Maybe start with some streets in some the neighborhoods you like and drive looking for places. You could also pay someone to do this as well. ** as I type this, maybe I will start doing this...
Another thing you could try is getting private or hard money to offer cash when you put down an offer on a property that's on the market. After a year or whenever, refinance with traditional. I think a lot of buyers are choosing cash offers so that they can make sure the deal goes through and not have to deal with a financing contingency.
Good luck.
