It is difficult to get a man to understand something, when his salary depends on his not understanding it

My salary? I am a wage slave just like everybody else.

Anyway, you didn't address the main questions:

• Do you think providing exclusive access to a house for the renter to live in is something that has no value?
• This house didn't just happen to fall in my lap. I put 250k of my own money in over the course of 30 years (10 years to save for the down payment + 20 years of mortage payments). Money that I worked for, doing a job. It's literally the fruit of my labor. By what ungodly reasoning should I have to give that to you or anyone else for free?

It seems you are the one here who is not making any effort to be understanding.
