Does a wholesaler here in Florida have to use transactional funding and a double close?

Funds are typically wired.

Since I am likely to be forced to look for private funds or possibly a cash partner, what terms should I look for in a fair partnership or private funding?

I have two lenders that I work with that fund all over the SE.

Seems to me that if the seller doesn't need the money they would potentially make a far better return on their investment by using seller financing vs putting it in the bank or investing it in mutual funds or stocks.

Easy: Mislead the seller with bogus clauses such as 1. subject to partner approval (your partner can be your dog)2. subject to 60 day inspection  (they are tied up doing lots of inspections)3. subject to financing (just be sure and don't try and get it)If you use enough weasel clauses you won't lose a dime, will have raised the sellers hopes, taken the property off the market leaving REAL HONEST POTENTIAL BUYERS behind, and started developing a reputation (maybe not a good one).

I was born and raised in Dallas Texas.  

I want to try that first before raising money.

What would it take to become funded, as this is my first look at this type of funding.

Brandon's got a book on Investing with no or low money down, you will see there creative ways to fund your investments if you are low on funds.
