While prices have definitely moved significantly higher in the last 5 years you can still be all-in (purchase + rehab) for $75k-$95k on a decent C/C+ rental that will appraise for $85k-$110k.It's a great market to BRRRR if you'r working with a team that understands what they're doing.

I only have 12 months to pay the cc before the interest kicks in and my limit it's about 20k would be enough to cover down and closing expenses.

Our property owners all sign and get a cc of the completed lease via DocuSign right when it happens, there is no good reason you are not receiving a signed lease when requested.

My idea for an alternative is to use Bill Pay and just register the CC payment by transferring from the checking account and writing a "check" from the CC account for all the bills paid in that period.  

See if you can get CC's in on every email from the Section  8 office and the lawyers office.Everyday, call your PM and ask what she has done for you lately. 

Also on Airfare learned a hard lesson to.. you must have paper receipts and boarding pass's to write them off.. copy of CC bill and or on line status report is no good

I would try to find receipts, at least contact credit card company or bank for checks or CC receipts.

I don’t mind seller finance deals but I don’t recommend them in cities like CC, the poverty rate here is way too high and I see this happen more often than not.

You should have a separate bank account and CC's for the LLC. 

Are you doing it via CC like your STR guests?
