Once it's done you can give them the rest of the money for the house and should be able to walk away with a good profit. 

Investment-wise, I purchased a single family home in Lancaster, CA back in 2010 which I unloaded last year for a decent profit.

Never use leverage to create a bigger portfolio that gets you more equity and profit?

I guess what I am looking for is someone I can achieve both of these objectives with as a broker I can hang my license under and someone I can pursue wholesaling deals with simultaneously.

I don't want to sound like a scavenger looking to profit from their misfortune or take advantage of them.

Paul,...If you're going to wholesale like a professional, only pursue deals that are worth Cash Buyers' time (target for 60% ARV if you're not confident about estimating repairs)Some wholesalers aim to lock up as many houses as possible and then walk away when their 2 cash buyers won't buy [bad] deals.

and which of them can make the best profit ?

In addition to what @Paul Allen said, Look at this as two steps( does not matter if you have an entity or without entity) 1st: You will pay tax the profit of the flip.

I've ran across "weird" properties too that make me hesitant but I think mostly anything can be made into a profitable deal. 

We want to pursue a BRRR strategy in either the Norfolk county, Worcester county and Merrimack valley.
