How can I invest in Apartment complexes and live for free?

[Brian V.]

My wife and I are retired. We make about $30,000 per year. Its very modest. We have $20,000 in the bank and about $50,000 equity in our house if we sold after selling costs and real estate commissions.

I had an idea that we could somehow sell our house and buy a small apartment complex. We would live in one unit for free and maybe collect a small monthly income after the mortgage and all expenses.

Does anyone have any ideas or resources on how we can accomplish this?
