My future plans for the company would be to use the knowledge, skills and contacts acquired to develop/Remodel/maintain my own real estate investments.

His attorney has suggested we secure the loan with a pledge of stock in his company, but I'm concerned this may come across as a partnership and trigger UBIT.

As the years past, we had all of our money in stocks which we lost a lot in 2008.

Its much like looking at stocks and comparing how well each has done and looking at its 10 year history, like Benjamin Graham taught.

Plus you'd have access to 401k funds to invest in things that return better and less risky returns than the stock market.  

thanks everyone I think I might have to do the cash for keys but now I have to figure out a date to do it and the place is well maintained (surprisingly).

@Getachew Hundera,Another source of private lenders is anyone with whom you establish a personal relationship (prerequisite to private lending per the SEC) who would consider investing in your deal.Essentially, it could be anyone who is nervous about the risk and volatility of the stock or other markets and is looking for a safer investment secured by real property.Learn how to attract and engage private lenders other than your family and your current friends and associates.

So, in the quest of finding opportunities and trying to make sense of what niche is better suited for my passive style of investing (which I see myself as), I came across this GC who does everything, even maintain books.  

—In all criminal cases, contempt cases, and other cases filed pursuant to this chapter, if a party has sold, leased, or let real estate, the title to which was not in the party when it was offered for sale, lease, or letting, or such party has maintained an office bearing signs that real estate is for sale, lease, or rental thereat, or has advertised real estate for sale, lease, or rental, generally, or describing property, the title to which was not in such party at the time, it shall be a presumption that such party was acting or attempting to act as a real estate broker, and the burden of proof shall be upon him or her to show that he or she was not acting or attempting to act as a broker or sales associate.

It is more secure and means that they cannot lock themselves out since they always need a key to lock the door.This is a problem you have to fix today so you need to install whatever Home Depot or such have in stock, but I have finally seen the light and am switching to Landlordlocks iCore locks.
