Step 2 Troubles in getting my next rental property

[Jameson Waltz]

Feeling a bit lost. I bought my first rental property (with a mortgage) almost 2 years ago. I profit about 135/mo. So not much. I don't know how to get property number 2. My market is now officially too expenisve to be apart of. I have 180k to pay off the rental. so essentially 28 years. is there a strategy to get number 2? With the rental and my  home, and I would have to be making much much more money to get qualified for another loan, on the other hand, I could sell my rental and use the money to purchase in full somewhere more affordable. Advice is much needed.
