I read more and more stories around the web about people who were duped by bad mortgages, usually in the fine print. You need to be very careful when securing a loan, particularly when dealing small lending outfits.
This isn't said to make you believe that all loans are done with bad intention. However, as more and more investment opportunity presents itself, a lot of investors are going be wanting to secure loans quickly because they are looking at the payoff from the investment, and not factoring in the costs associated with the loan, in both the short of long terms.
Be diligent in analyzing your loan before signing. I have any seen associations mentioned that will review your loan at low or no cost. I don't know what they were off hand, if any knows, please list them here.
