Weirdly, I had to create a new account to post this, every time I've logged into my account it gives me a http 500 error, or some other reason the forum doesn't work?

I've waited weeks to ask questions thinking my account needed to be activated.
I'm going to see the boat tomorrow, and I'm hoping to get some ideas of what to look for and if it's reasonable.
Background on me
I've always dreamed of living on a sailboat, ever since I got into my dad's copies of Great adventures in Small Boats. I read many books on bigger ships but those first stories always stuck. Never had the money to make it a reality.
Recently I've come across what looks like to me at least a very good possibility to finally make this dream a reality.
I'm trying to collect all relevant information and make a good decision on this, as I am looking at a very serious investment, and tying myself down for the better part of a decade. I figure this would be the best place to ask about the boat itself. I'm motivated to make this happen, I'm not just another university kid dreaming of some idealistic work and stress free life floating around in a boat. I've spent the better part of a decade working heavy industrial jobs, I went back to school after enough injuries and damage to my health. It's given me a useful background of skills, from CAD for part layouts to running CNC controlled water-jet cutters to simple machine maintenance.
I'm comfortable with wood/metalworking, anything from turning wood on a lathe to gas/mig/tig welding. I can dive, am comfortable underwater and have my own dry-suit/tank.
I'm comfortable living in less than ideal conditions, and spent roughly 8 months last year traveling south to Panama overland on an old CX500(70's Honda motorcycle).
I'm looking for a boat to live on and sail long term, blue water sailing eventually, once I have the experience to make it feasible.
I have a reasonably well paying, stable full time job, and my expenses are now extremely low.
I have sorted out all my bills, transportation etc to the point that my only recurring expenses are 68$/month for phone(including all usage).
65$/month for cable+internet
4400$/year for university tuition.
As a percentage of my income the mortgage for the boat would be approximately consistent with my current rent(50% of income). I will be an additional 250$/month into a emergency/maintenance fund.
Does this sound affordable? In terms of actual dollars, after all currently calculated expenses I'll actually have 3x more income left over after expenses than I've had in the past 3 years.
My father will be helping me with any planning for
repairs or upgrades, as well as teaching me to sail. He's got decades of experience with most aspects of sail from
repair to navigation, though he mostly races small boats these days.
The Boat
Other than a one page spec sheet on saildata.com I have found no information.
DISCOVERY 47 sailboat specifications and details on sailboatdata.com
It looks a bit different from the blueprints I found on saildata, without the portholes set into the hull, and larger windows.
What should I look for in terms of issues and possible damage?
How would such large windows cope if I wanted to sail off-shore?
What would be the minimum crew possible? I'd prefer to sail solo once I gain enough experience(thinking 8-10 years away).
What kind of upgrades should be performed immediately?
Asking price 135,500$(+12.5%tax)
1983 Discovery 47' Center cockpit
Last surveyed in '08.
Had an
epoxy bottom coat put on in '88, due to blistering, all blisters less than 3/8" but there were lots of them. Owner says the last time it was out of the water(two years ago) he filled approx 40 of them, all smaller than 1/4" in diameter by grinding them out with a Dremel then filling with West
epoxy.
The couple who own it currently live aboard, and have done most of the work themselves.
