I finished my business plan finally recently.

Their entire business plan is wait a few days to come out, charge  deductible, go back to the office to order a part or two that will come in a day or two.

It's running a business NOT renting a house.  

Terms such as interest rates and payment schedules are typically negotiable.Combining creative financing with seller financing can include strategies like:Subject-to and Seller Financing: Taking over the seller's mortgage and financing the equity portion through the seller.Lease Option: Renting with an option to buy while negotiating seller financing for part of the purchase.Wraparound Mortgage: Keeping the seller's existing loan while they finance a new loan that includes the balance.To proceed, consider connecting with experienced investors, understanding local legal implications, and attending networking events to gather insights.

What broker would sponsor me considering I'm not intending to become a full time Realtor and give them regular business?

Its not personal, its business. 

I'm excited you are here and ready to grow your business even more! 

It’s a business account and I just checked, paying 3.95%, more than my personal one!

For bigger, more complex projects, it’s better for our business to wholesale them to other investors.

I'm considering buying a house in nearby Palm Coast as I travel there for business.
