One thing I continue to think about is how valuable 2-4 unit properties are becoming, and will continue to be, since Fannie/Freddie took the income restrictions from the 5% down conventional loan option for house hackers. 

We are wondering what to do next....multi family unit?

I'm in the Tampa Florida area and it has been very accurate for me and my units. 

I believe United FCU is best. 20% down, usually a 10yr term (they offer a longer term though), and an interest rate that's pretty close to the current average for conventional loans. 

Most ADU's are one bedroom units and rent accordingly.

I could see a requirement, perhaps under the Patriot Act, that requires all landlords to get a SSN/TIN from everyone living in a unit and report that (or lack of) to the federal government.

I am currently in the market to purchase a tri-plex with the plan to live in one unit, make upgrades, and rent the other two out.

Paid a little less for an apartment unit in Arkansas, but it was much smaller.

They provide fake checklists saying units are repaired according to agreed-upon inspection reports only to walk in to a home that is more damaged than it was during escrow.

On property number one, I would cash flow $750 a month after mortgage, taxes, and insurance if I also rent out the unit I live in.
