They want you to pay a small fee depending on how much you borrow, it's a percentage. 2 people I know has been banded from 3 groups I'm apart of because of fraud practices.

How much, either percentage or amount, should be good to give her?

You will also provide a percentage of the sale to a real estate agent and possibly at closing so you may bring in even less.

How can I sell these leads to agents for a percentage of commission if the deal closes if I am not an agent and cannot use a typical referral fee?

@Gerald Koonce They can assist you on both but they cap it to a certain percentage (LTV) of the ARV. 

Should I offer them some sort of equity percentage? 

The thing I am asking  is what percentage discount this deal is worth? 

Other than what the marketplace accepts at the current time, the experience of the sponsor, type of property (and risk associated with it) all play into the percentage you determine for the Pref. all the best!

I will be a passive investor who will finance the flip and my partner will do all the work and we will split profits according to our agreement.My preferable way would be to buy it in the name of the LLC I own 100%, my partner will deal with contractors and does all the work needed, my LLC pays for everything, we sell the property and my LLC pays my partner agreed percentage of the profits as a project management fee.Can I treat the income from such an activity as passive and avoid self employment tax?

Since Dan will be a long term partner for the business, I'm leaning towards more of giving him a small percentage of the business.
