Maintenance consists of hosing them off occasionally if you choose to but it’s not necessary, rain will clean them off sufficiently if you don’t want to clean them (I don’t clean mine except very occasionally during droughts if I notice them getting really dusty).

I'm a real estate agent in the bay area and have found that three and four-unit buildings with FHA loans don't ever pencil out because of the "self-sufficiency test".

Have you Dad give you a loan for around 100 million dollars and inherit part of his properties as well as your grandfather's organization (Trump Organization), and there you go.With the 100 million and real estate network already in place, you have the sufficient leverage and wiggle room to take the necessary risks and scale at a fast pace, then make cutesy catch phrases to impress naive teens and the uneducated.In conclusion, prey on the poor and weak, take aggressive measures against them, keep raising rents in these units while avoiding maintenance, and use the large cash flow to buy marquee properties in cities after multiple generations and 50 years of the money working for you.Capiche?

If the population is declining, stagnant, or increasing slowly, there will not be sufficient demand to rapidly increase prices or rents.So, we know the first requirement for selecting a city:✅ Significant and sustained population growth.Income PersistenceThe only way for your income to persist is if your tenants remain employed at jobs paying a similar wage.

I know it would need to pass self-sufficiency test for FHA so I'm wondering what financing you used. 

I have a purchase agreement and an assignment contract, and I'm curious whether or not my documents are sufficient for Minnesota and the metro area.

A quick check with the local ordinances is probably sufficient.

I'm not clear on that either (the memorandum) - a signed Purchase & Sale Agreement with the seller is contractually sufficient.  

My understanding is that the platform requires the city's "Rental License" but I am not clear if this is sufficient or is there another requirement?

Maybe the interst you'd pay would be sufficient.
