I would like a little understanding

[Account Closed]

Okay I don't understand lets say for example a house ARV is 319,000 and the house need 35,000 in rehab and I get it down to 94,200 the (MAO) on the purchase and sale agreement. Then I find a buyer and sell the contract to him for the house for 188,300

What I want to know is the seller gets paid 94,200 dollars and the buyer pays 188,300 to own the house and the buyer pays me for getting them a good and no money comes out of the sellers pocket I am asking if I got how things go right 

Also if a seller ask me how I get paid exactly what should I tell them the truth or something else I am worried that if I get a very large amount of money (hypothetically) they will feel they are being tricked I would like to be honest because I have no intention of cheating anyone out of there money.
