The first is whether or not I discuss all the details with the buyer or do I send over the buyer's info to the company and let them work out the deal.

If it were me I'd talk to the realtor anyway and work out a deal for him/her to handle the transaction.

Hello I am interested in buying a rental 6 plex+.I have a contact but my first experience with him didn’t work out good.Would appreciate If some one give contacts of contractors and good real estate agent.

Ive already made great progress.And I would like to get back into a workout routine (im heading in the opposite direction as you with weight).

That lends itself to be a much better play for some one like you, who can use six, maybe seven figures to build a reasonably diverse portfolio in the state and, if they win, great, but if it turns south or takes more time than predicted to work out, has the ability to carry the investment until it rebounds or can take the haircut and go about life.

Also, is there added value to contracting this work out to a security professional or company?

My direct friend met him through work a couple months back and asked if I can help work out some sort of deal since the home owner really doesn’t want to work with a real estate agent.

Finding a good GC in this market has been such a massive issue that I literally acquired my own truck, equipment, and warehouse to do most of my own work out of necessity.  

@Daniel Dietz That sounds like it could work out to be a great situation. 80-90% leverage inside a Roth could end up with massive tax free compounding.
