An unsecured line of credit like a credit card?

Put yourself in a position to win, my friend!

You can really create a win win there.

The rehab was $50k, I put it on a 0%apr credit card.

For now, work, build your credit, get 2 credit cards (long-term, this helps your credit score as there are more accounts you are paying down).You could find an investor, use your money for the down payment, split profits 50/50 You could also apply for an FHA loan, have your mom co-sign with you, put up your own capital and proceed from there.

i lost the keys to my workshop and was able to use old credit cards to get inside.

Even a worst case scenario is still a win/win and no one walks away feeling like they were taken advantage of.

The borrower sees whatever numbers they want for things that don't matter, the underwriter sees the accurate numbers that they actually need to be accurate, and boom everyone wins. 

Focus on the big wins in real estate like buying more deals and creating more value. 

It’s a win win situation.
