One solution could be a Debt Service Coverage Ratio (DSCR) loan.

Best thing to do is avoid the higher DTI debt to income, claim one as investment and use the rents to offset the new purchase. 

When you can simply cooperate with me on seeing for housing assistance and have the US Federal Government pay for all of your rent debts?

I am not a debt investor, a bond investor nor am I an investor in corporate debt, private equity debt, peer to peer lending, etc.  

Yes  I think the best move here is to asses your total monthly debt and see if a cash out refi will help decrease the total interest and monthly debt obligation.

Everything you said is exactly why-- debt levels, market demand, associated costs(taxes & insurance).

So far mostly people are telling me I'm probably stuck until their lease is over. meanwhile I also need to pay down my debt and improve credit score. 

If you want the least amount of paperwork, you could consider refinancing into a debt service loan.

NO debt NO debt NO debt on rentals is the way to go as you mature in age as an investors.

For example a 25 y o applicant who has used credit minimally and has an unpaid bill of $50 in collections from when they switched phone carriers may have a low score, but the only negative on their credit is this one SMALL $50 debt.
