Luis, if you can hold on to your current rental situation for a few years, I would do it without thinking twice. If its temporary, then thinking about what to do next is great.
Instead of concentrating on purchasing a buy and hold property, maybe you should think about getting your license and generating extra income through being a realtor. You could use this to pay down some principal on the 11.25% private loans or save for down payments. I would not worry about the loans at less than 4% until you are in a much stronger position.
Just remember every time you pay those loans down you get a guaranteed 11.25% return on your money. (Money saved is money earned!) That's a killer rate for a guaranteed return.
The personal finance forum is great. They wont recommend a lot about RE, but they will help you sort out your income, debt, and budget to get you in a strong position for when the market is offering a little better deals than it is today.
