In my experience, cost segregation studies are a lot less than $10-15k especially for smaller properties (6 units and below).

You should start with a focus on a 2 unit multifamily property in a market that you can afford to get into. 

I currently have 1 two-unit in Joliet. 

Hi, Just bought a unit via LLC in Nashville area, specifically in Berry Hill to operate as STR.

House hacking can work with an FHA loan, as rental income from other units might help you qualify, but be sure to consult with a lender or mortgage broker to explore flexible options based on your unique situation.Good luck!

Based on that number of units I would expect much higher figures - did you buy these buildings all/mostly cash?

$132,500/unit for 2/1s in Hampton is too much IMO.   

Leverage & Portfolio GrowthInvesting in a solid multi-unit property allows you to leverage your capital into an appreciating asset that generates cash flow.

My daughter went in on it with us- she will own her unit, and we are renting out the other 2 units. 

Some food for thought: there is no such thing as an unsubsidized unit of energy in the U.S.
