I now track my final sales cost against my original estimated ARV against what the best/closest comp was when I first did my ARVs. 

Do you have consumer debt (car notes, credit cards, etc.)?

Almost all DSCRs require a personal guarantee, and PG'ing a loan WILL have the exact same effect on your DTI, regardless of whether the DSCR lender reports it on your personal credit report.

Tracking your net worth as a real estate investor can help you make informed financial decisions.

@Seth SmithIs that in place tenant credit worthy and strong?

Got agency credit with a fixed rate for seven years, will probably sell before that point.  

What credit score do you think tenants qualifying for government assistance will have?

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Always ask for an LE and a rate sheet if the lender can provide it without pulling your credit.

If your property doesn't have a mortgage, you can either get one or get a commercial line of credit.
