Pay off Debt, Invest, buy a home, &/or just choose two of them?

[Allan Guerra]

I have been renting a small apartment for over a year in order to pay very little in rent and therefore save to invest, and my family and I are a bit tired of being in such a small apartment. We have been renting out an apartment we own, but the rent is $70.85 less than the mortgage payment. I was thinking of using $10K to pay some of the mortgage to lower the monthly mortgage payment to be about $26 less than the rent we will receive from it so it can finally cashflow. And then maybe use the other $10K to invest in another property or use that amount to buy a personal residence where we can be live happier in a larger property. What would you do in my situation?
