Apartment complex or bunch of doubles?

[John Gach]

So I’m trying to get into real estate, I have a 4 unit I’m renovating currently, once it’s done and rented I plan to pull equity to buy the next apartment.

I’d love to own as many properties as I can eventually, but am I better off buying a bunch of doubles or is it better to go big and go for buildings with the most units I can find even though generally the return isn’t as good, but is it still better for other reasons going with apartment complexes?

I’m in Buffalo ny

Thank you
