Since you will be having a steady income, you can choose to go in multiple directions.

The standard thing that happens is that whatever is left of that $40k outstanding amount owed goes to pay off that debt, so the house can be delivered free and clear of clouds on title as specified in the purchase contract.If the buyer is an idiot, or the market is so hot that the buyers are forced to behave like they are, then you do sometimes see buyers take over the solar lease or solar loan (PACE loans are common in California) or solar whatever it was. 

At worst, the HSA behaves much the same as a tIRA after age 65.4.

The 16 year olsd is probably going to be having friends over quite a bit that spend the night.....and of course the adult companion (male or female) will be there a LOT with a child of their own.

Ideally someone local as I will also be having the house inspected and possibly appraised.My aunt is moving out of her house of 20 years.

The most difficult owners are those with unreal expectations and who don't want to spend $$ on their properties.Drawbacks to your job will be having to deal with emergencies from time to time. 

We are starting to get some people together for BiggerPocket meetups in the Greenville area and will be having another one soon.

This has come back to bite me in the behind with the tenant trying to pay late every month (BP has helped me to stay firm on this point and I am still able to get the rent on time every month, but it's always a fight with the tenant calling me "unprofessional" for not letting him drop the check off "sometime next week"), and a dog despite everything in the listing and lease agreement saying "no pets" (I let this one go with a Pet Addendum and an extra security deposit because the dog was small and seemed well-behaved).  

Second also, not all market are behaving the same. 

Further more, some ideas to generate leads would be finding tired landlords, Send mailers to out of state land lords, Drive neighborhoods looking for vacant and abandoned homes, Talk to the mail carrier and other delivery people because they would know the empty houses in the area, Mailers to Landlords who own more than one property with back taxes, Mailers to Landlords who own tax delinquent multi-family properties, Place “We Buy houses” flyers/business cards at unemployment offices….a lot of people there could be having trouble with their homes and may need a solution, One-page Flyers posted on bulletin boards at large stores-get approval from manager though, Using Craigslist to find sellers, Send emails to craigslist ads with apartments for rent (the emails go to landlords who may be looking to sell, or buying more properties) Target people who have been transferred (job) and must sell NOW, Military transferees, Move-up buyers-People that need to sell and get a bigger house but feel stuck free & clear houses because they might sell with seller financing, Network with moving companies, Network with termite (WDO) and pest control companies, Network with real estate servicers – title companies, insurance agents, mortgage brokers and lenders – everybody knows someone in distress, Network with credit repair companies to assist their customers that must sell, Funeral homes and obituaries, Houses with boarded up doors and windows, Houses with blue tarps on the roof, Network at your local real estate investment or landlord association, Network with your sphere of influence - hand out your business cards to everyone you know- you may learn your neighbor has a friend that needs to sell a house etc.
