Most are folks that have the emotional control of a 5 year old, controlling attitude, an omniscient narrative in every thread & topic, act like an online hall monitor, and constant attention seeking. 

I would like to find a reliable wholesaler who has agreeable ARVs and Comps and leaves "meat on the bones", but of course still is able to have their fair cut of the deal. 

So no, tis is a horrible deal for you.Now of course I know nothing about your property (since you provided so little detail) so if this is a huge 5 BR house with pool on a lake somewhere, then you need to adjust my numbers.

I think they just started offering it again.Dyches Boddiford has a good course https://assets101.com/events/hard-money-lending-online/I and several others have taken it.

"Good about deductions" sounds a lot like "doesn't make enough money to be a homeowner", so he should keep renting from someone else, and you should do what you're going to do with the money and wisdom you earned.Of course I don't know your son, but I think this is too dicey and you are too close to the situation.  

I just stumbled upon it online and I’m trying to research it myself. 

Sometimes you get lucky.You could even bring up the subject of seller financing (search online for ideas of how to structure a seller financed offer), and make sure a competent real estate attorney helps write the offer documents (if it gets that far). 

I've wanted to know some tips you guys have on wholesaling and starting young and what I should know before I start.Important question: How can I calculate or give an educated guess on a property's repair cost on zillow 

Of course we all have to start somewhere but I tell everyone I do business with regardless if it's with me or someone else I always recommend them to build a portfolio.

Their online reviews on google seem great and everything is 5 stars but I promise you the team is terrible.
