However, if you are looking to use it, pay it back, use it again, pay it back......like when you flip for example....then a Line of Credit is PERFECT for this. 

I use quickbooks online (I bet all the quickbooks softwarewill do it) You send them An invoice in there email , they can pay by check online, totally free for the check online but if  you forget to uncheck the box to allow credit card charges, then they will have the option of paying by credit card (3%fee deducted for you)Thier check paid online through quickbooks takes over a week to fund , that’s the only downside 

If you add some more details on the financials for the deals and what state they are located in and your credit, other BP folks can recommend some lenders for you potentially.

I was confusing a home equity loan with a home equity line of credit.

You have to have some cash, an entity and a decent credit score (over 650), but it's doable. 

What are typically the best places to open a Line of Credit on a home?

I had zero credit, and we didn’t have the two-year income history needed when you are self-employed.

If no one with more expertise responds with a better suggestion, I recommend you start with finding out what some local banks/credit unions have to offer.Good luck

Also, I would need to know who’s credit and guarantee is involved as I would check the applicants background before approving an application.

My current credit score is 650.
