Now that I'm looking at purchasing properties, I'm wondering if I should find a broker to hang my license with, get trained on how to do the paperwork, in exchange for a small flat fee, as I will be doing most/all of the legwork.Also do most brokers require their agents to be part of a realtor's association?

What degenerate circle of people have you been hanging around that gave you that warped perception of the American way of life?

I'm no lawyer - so take what I say with a grain of salt - but if that one line in the lease is all they are hanging their case on, it seems weak. 

Just not sure if I should hang on to it or just sell and purchase something else.

@Tony Castronovo, that's what I'm seeing as well, won't say that there are no deals out there, but it's a competitive market going for that low hanging fruit.

I am looking for a small independent/boutique brokerage with whom I can hang my license.

Second, I arrive home from that meeting to find a herd of nine deer  hanging out in my yard--reminding me that I'm in a prime location with easy access to the outdoors, great neighbours, and 10 minutes from work. 

Use a split-system HVAC unit that hangs on the wall to handle all the heating & cooling, it's very cost effective and they work great for open layouts, you can hide these easily. 

Are there any concessions I should look for including in the contract to incentivize me to hang on and wait?

If so and its not habitable then that may be the hang up.
