I am originally from the East Coast, and hopefully can take whatever skills I learn here, and apply them back home whenever/IF I move back. 

Next and perhaps more importantly, when a buyer is not represented I have no idea if they are qualified and very often they are not.

For question two, I got pre-approved about 5 months ago for that loan - so I was thinking (all things consistent) I would be able to still qualify for it? 

As @Jason DiClemente said, consult with a qualified tax advisor.

Been in the solar industry for 4 years.Typically the sellers options with the lease are:1) Transfer it with the sale of the property (which assumes the buyer is qualified and willing to accept the lease - qualification usually based solely on FICO score).2) Pay off the lease (usually according to a payment schedule, which may include early termination fees).Option #2 can be really expensive.How old is the lease? 

She can qualify w/o the rental income. 

I've forgotten the reason my lawyers had advised against it but usually the people can't qualify for a loan and while I own my properties free and clear, carrying the mortgage doesn't achieve my goal of generating cash so I can reinvest or work on my other projects. 

Focus on honing in one skill that makes you more valuable in the workplace.

At the time of the sale, the old guy will "qualify" bidders (Look over their cashier's checks) and then will announce the postponements and cancellations first.

You have many options for low down payment on a duplex (2-Unit) these days between FHA, Home Ready and Home Possible (if you or the area you are trying to buy in qualify).
