As a self-managing landlord myself, I've avoided sending such letters except when I have to, and I always make the phone call first and the letter is a legal formality that comes later.Now, will I do business differently if I get to fifty doors and in-house property management?

If I had a tenant do that to me, I would file for formal eviction right away. 

In Pennsylvania when a property doesn't sell at the Judicial Tax Sale (Free & Clear Sale), it goes on a list (Repository List) where it can be purchases anytime for a nominal price.

Any formal arrangement and payments in this situation would just be you shifting money from one pocket to another, there isn't an income tax effect either way.If you flip the healthcare business to a regarded entity, like an S Corp, it's very possible the arrangement will work as long as everything is done at an arms-length and fair market manner.

You should be able to leverage that experience even if you are not getting formal education.However, that being said, if you can put together a Business Plan with all the calculations, especially the IRR over a 10 year holding period, combined with your Commercial RE Experience, that would bring a ton to the table!

It keeps it easier to respect the formalities of all these different ventures. 

Its your responsibility to judiciously spend deposits. 

It seems to me that I can challenge the lender advising that I’m not obligated to honor their demand, and to force me to do so would empower me to file a formal complaint with the state Attorney Generals Office.
