I've found that larger (80-units or more) apartment deals that come from wholesalers are usually a waste of time - mainly because the financials (like T12s, Rent Rolls, etc) are incomplete. 

But I don’t want to rent out whole house because then I don’t have regular access and rental income is much less.

I personally like investing in B and C class apartment communities in high growth markets (population and jobs). 

But when we went to the first apartment, tenants told us that nobody notified them.

She kept the apartments maintained and heated (one one system and service now) but never rented and legally converted it to a SFH with the town. 

Is there a lot of visibility from the road, high traffic counts, great access in and out, plenty of parking or if urban core high walkability score?

How do you get access to a MLS guest portal ?

In South Korea, for example, if a person(not a certified developer) has a valuable raw land and desires to build apartments without enough money for from building to maintenance, he or she has to meet with designer and architect.
