I love the community in here.

At the current moment it's actually an obstacle, as I'm having trouble finding a broker who will let me hang my license there and not want to split wholesale assignments fees 50/50 or 60/40 because they consider it real estate brokerage.  

My wife is a doctor and she is a part of a regional group (200+ doctors) and practices with 4 other doctors in her office.

I have an agreement with him to seller-finance 70% of my purchase price and I suppose this inherently incentivizes him to deliver on his end, but that's not terribly comforting knowing my only recourse if something goes wrong is to walk away and lose "just" the 30% down payment. 

If the above scenario is legal, shouldn't I put it on the Market this year that way the business would inherent a renter?

Maybe someone else can jump in here as I won't be back to my computer until tomorrow.

She made her first investment at 23 and is in her 30's now.

I would love to use this to invest, but my obstacle is financing: I have a foreclosure on my record from October 2010- which matures October 2017- given the conventional financing rules (?)

Success is never just handed over, but comes to those who are willing to learn from mistakes and find a way to overcome obstacles.

So, your obstacle is not knowledge or experience, it's the lack of a deal in your hand to shop around to the funding people.
