Multi-family investing in PG county, MD

[Yi Zhao]

Hi all, I currently do flips in PG county Maryland. I've been thinking about doing some buy and holds. Seems like from the BP podcasts that duplex, triplex, etc are a good way to go. However, I haven't found any that would even get 1% monthly cash on cash return. The multi's I've looked at are triplexes around Tacoma park and college park for 350k-ish. Seems like single families around 100k-120k have much better cash on cash return in PG. Am I doing something wrong?
