I'm fine with that but within those bounds, I would like to select the most personable, financially stable, and longest-term tenant interested in my property.

We would then rent a new space in the same park as our current main office for about 10k a month and have that be our main office.Assuming both situations work just as well for the company as far as patient treatment and meet all other needs, which would be the best move financially moving forward for my partner and I? 

You can deny if: They cannot afford the rental, evictions for non-payment, recent bankruptcy, financially reckless behavior, etc.

It doesn't seem like it's worth it but financially owner finance would be the only way I can obtain a property right now.

Because most of the people I know are not that secure financially.

Having an LLC will also protect personal assets from financial liabilities (e.g., business losses and foreclosure), as well as, accidents?

Are financial institutions starting to make use of the DOS clause more today than they used to or is this still a rare scenario? 

@Bobby Nilsen First of all Congratulations on your success and kudos that you were able to leverage knowledge and networking to your financial success and cashflow.

Suddenly I had enough money to pay my bills, with a cushion to spare, and—at the urging of my sister, who had been interested in real estate for a while—I came up with the audacious plan to buy my condo from my dad.I had been a homemaker for many years before becoming a professional author, and had relied on my husband to take care of all financial aspects of our marriage.
