I would keep detailed records of my deals to include photos that I could use later when I am approaching a potential funding partner.

HI, Is opening a LOC on my primary a good option to fund flips or is there a better solution to get the funding?

@Michael Klinger  As others posted, SoFi and Discover personal loans are good options and I've used them in the past.  2-3 business days from application to funds in my checking account. 

Who was their funding source?

I was under contract for a property, and the financing fell through due to the property not meeting the lenders requirements and not being sufficient.The seller is trying to keep the EMD as I have signed and requested the mutual release.

For those of you who’ve chosen the fund route.

You will need to find partners, you will need to travel to where you wish to invest, you will need to understand the ins and outs of the business by being actively involved and treating it like a business and not some super passive investment.If you don't want to do that work I suggest you just put that 200k into some sort of diversified mutual fund that can make you 10+% on your money without any of the work of real estate.At the end of the day this is just my advice and I'm only a stranger on the internet.

Sound like Fund & Grow business model for $3500 for the year.  

When you pay the invoice/expense in the AP queue (i.e. transfer funds from your operating account to the AP/CC account) it show as a payment for a specific expense/invoice?

If you're considering private funding or investor partnerships, now’s a good time to explore those.
