hello I'm Rupert from Arizona, new to the game but shoot for the stars trying to be rookie of the year.

Going to attempt to summarize everything up to this point.Current Stage of construction: FramingWe purchased this lot about 3 years ago for $6000Have built 3 homes in this same neighborhood, this is our 4thTook about 6 months of re-zoning to allow for a variance in the rear of the property so we could maximize the size of the home, mainly to accomadate a master bedroom downstairsLot was vacant, cleared out a few trees and started on the foundation, concrete slabAltered the plan a bit so that the patio faced east instead of north, thus making it open to the patio.Project Description: 2-story home, 3 bed, 2.5 bath, 1 office, 1 game room/4th bed2808 sqft,  Lot  6,568 sqft        

My investment company typically purchases buy and hold income properties and it's hard not to notice the money left on the table when you make a half million dollar purchase or sale, so I decided to become licensed. 

I'm new to BiggerPockets but I am not new to the real estate game!

Yes, you may be out of a few dollars due to interest but this is a part of the game.  

Good Credit, guaranteed money back, skin in the game (money down)????

If the buyers feel like they should get more money, they can do one of three things:1) re-negotiate with you to amend your original contract2) walk away from the closing table and refuse to sign (basically bringing the deal to a halt)3) suck it up and sign.I can't imagine a closing attorney would hold money back for any reason, unless he had it in writing and signatures from both parties that money was to be held back... that seems beyond me. 

I am pretty open about my business and don’t mind helping follow BPers because I really believe that real estate is not a zero sum game.

I found the deal and he brought the buyer to the table.

To be the former and in the game for the long term I'd encourage you to start out with the right mindset of what it takes to build a long term business and forming trust with buyers and a good reputation is a big part of that.
