I used to have only SFRs until I had to carry them a few months with nothing coming in and only money going out in repairs and rejuvenation. I bought apartment buildings and courtyard units and took advantage of economies of scale. A two hundred dollar water bill split among 8 tenants isn’t too bad. Losing one tenant and only getting 7/8 GSI didn’t really hurt either. Unless you are getting something with a GRM in the 6s or 7s, I wouldn’t think about it. 10 is just crazy.
