Mike, I think you've gotten enough advise. What you need are answers to direct questions about your financial situation and hypothetical plans for the future. By the way, no one has a crystal ball and all this advise could be a waste if FHA regulations or mortgage programs change. We don't know whats going to happen for sure next month let alone what may happen a year + from now. The market is starting to improve and your option to buy that 4 unit may not last forever.
