Good luck  We currently have around 30k in personal loans/credit card debt. 

You can take some of the CF from your investment and give them a gift card to grocery store or something similar on a monthly basis.

If it's an SFR you could technically get a HomeStyle reno loan on it, but that would be a lot of closing costs and other nonsense just for an extra $5k.I'd suggest credit cards or other unsecured borrowed funds -- get it done quick and sell it quick to pay it off. 2nd best might be some sort of equity deal with another investor who has $5k to invest. 

Very polite, proactive in the application process, had good references from previous landlord, has good/stable employment, and when I looked them up on Facebook their information matched everything on their application.Unfortunately, they are not able to complete the screening due to a complete lack of credit history (young applicant with no credit cards or, evidently, student loans).

The only way you can have it accurate if you balance your books and reconcile your bank and credit card accounts.

We are looking at closing soon, barring a catastrophe, on our first investment which we intend to flip.  We plan to purchase the home outright with a HELOC we have out currently with plenty of access to funds left ove...

I did realize pretty quickly that maxing out my credit cards was probably not the best way to manage my real estate investing, so I canceled the mentoring within a day and got a full refund.  

We paid off some credit card debt and decided to move home.  

Student loans, business debt, credit cards, you name it.Would it make sense to spend a bit more on the reno and sell each unit as a condo?

Investor should get a business account for credit card payment (minimum limit) and a bank account hooked together never give them your personal account info.
