I would find someone here or a person at a local REI  to help you get to another level! 

I'd pay the loan payments with the proceeds if my STR cash flow isn't enough to cover it but just until I can sell each of the units next year. 

Rose,Yes you can purchase as a primary and rent out the other unit as you see fit STR or LTR.

If a large investor with 100 units wants to use you as their PM and their portfolio is a great fit for your business I know for a fact that almost every PM company will play ball and negotiate fair terms.

My wife and I are considering purchasing our first 6 unit apartment building.  

I am planing on purchasing a 4 units multi-family in FL.

You can collect all the rent and late fees in full but if your unit turns over yearly and takes longer to fill you make LESS money!

I dont know the dynamics of every community of the United States, but under 250k multi in a class A/B community that needs no work is something I have never seen (in recent times).

I think its because no one wants to pay $50 PER unit to apply for a rent house.

I have a few rentals in the Denver area, and one thing I really enjoy doing is installing Life-Proof LVP flooring in units each time they turn over.
