I am not familiar with who you are working with but always recommend vetting any company deeply before signing and paying -- those companies tend to have a lot of overhead they need to pay - out of your bottom line.

Because of this, a lot of investors tend to pay cash to avoid these extra fees.

I have found that both are good, Propstream tends to be more saturated in regards to the amount of people using it.

For many newer investors once they're familiar with commercial requirements for 5+ multi family unit mortgages tend to refocus on more conventional residential transactions (1-4 units) with much lower borrower barriers to entry.

It sounds like you could get closer to 1000/room.Class A properties tend to not cash flow at 20% down. 

I tend to agree. 

Also very different behavior as far as how far in advance they book (the larger tends to book much farther out).

Tenants tend to take care of the carpet in their bedrooms.

Condos and duplexes tend to invite more litigation.

Real estate often appreciates in value over time and tends to perform well during inflationary periods.
