Wondering what are next steps, end of second year

[Collin Sabers]

Hi. Am fairly new to the rental game. I have 4 units, each cash-flowing pretty well. End of the second year and have acquired the 4 units across two different properties. They happen to be across the street from each other too. With aprs going up and resources limited, waiting on properties to produce more, where should I be looking. Are foreclosures a good deal, or maybe get into short term rental in hot spots. A little more conservative buying outside my market, I am self managing at the moment. 

Thank you for your time, anyone who read this. Thanks for your insight,
