How many units are you including in the $67,200? 

They aren't in a hurry and I've looked at similar units sold in this neighborhood and they're asking a very fair price.

What if you have an apartment complex with 20 units?

@Sean Dillon figure out how to buy a 2-4 unit with FHA loan.Then rent at least one of the units long-term for stable cashflow.Try STR in another unit as well as the other bedrooms in the unit you live in.You may even consider living in the basement, attic or worse unit in the building to rent everything else out and max cashflow. 

If looking to buy in the U.S, there are foreign national DSCR loans for 1-4 units.

To find value on residential 1-4 unit properties you could ask your realtor to run comps or complete a CMA(Comparative Market Analysis) on a subject property once you find it.or you can find the value on your own.We use prop stream to run comps. 

Investment Info:Large multi-family (5+ units) other investment.

I am trying to scale with larger properties (10+ unit bldgs.) so I am exploring different funding strategies beyond zero down and including OPM

It has been rented out as a complete unit for 3 years now. 

Congrats @Emily Pena - I'm also an agent (working mostly with investors), property manager and an investor myself (currently owning 26 rental units).
