Currently i'm just working with one lender (i was referred to them by a few different people), but i'm hesitant to get quotes from other lenders because I don't want my credit dinged by too many inquiries.

Couple tips: up front fee; too low interest rate, do not need your credit report or collateral.

They persuaded me to enroll in their class starting from 20 thousands to 50 thousands dollars and to use a credit card to pay for it.

@Torrey McGrawWe usually pull the credit history up-front.  

I’ve been working on my credit and I don’t have good enough credit nor much capital but I don’t want to miss out on this deal.

Can I get an equity loan with bad credit?

I'm 21, and I'm just barely starting to build credit.

A hard money lender would likely charge 8-12% interest.A home equity line of credit (HELOC) is running around 5 - 6%.If he invested his money with someone else, he would expect a fair market return on that investment.

Revolving Line Of Credit via Family Member: In this case, your family member allows you to borrow money as if it were a credit card.

If you insist on doing this at least do a background check to make sure they do not have any prior evictions or terrible credit.
