As a GP, I am involved in 1100 units $140M AUM. 

Also, the electrical panel is on the rental side and the AC is all currently one unit throughout the house.

Im indifferent to the number of units as long as the numbers make sense. 

Khu,You can easily get into more than just (1) Duplex 2 unit with $50K to $75K in cash reserves.

I'm on my second project, first was a single unit buy, fix, hold & flip in Antwerp.

I bought an 8 unit building 1 year ago with rents more than 50% below market value.

Ask how many units they manage and how much experience they have.

Meaning if I have a 10 unit building I don't want to lease one unit to STR.  

Directly North is still A market-Shawnee)It looks good with straight investor metrics using Fannie Mae conforming loans (25% down, 7.1% rate with a few points) and easy ARV monthly rent of $1700/unit ( I get this number based on the exact same floor plan in Raytown with complete rehab placing a tenant at $1500, and Raytown gets lower rents than Roeland Park KS.)

I did a 1031 exchange in early 2022 from a single vacation rental I had into two DST's, each are  300 unit Apartment complexes offered by Capital Square.
