This is EXCELLENT advice
I think you should look at 10 more boats before you buy one.
Five boats on, you'll breath a sigh of relief that you didn't buy the first one.
The search should be fun, and the more knowledge you gain the more fun it will become.
I've looked at probably 15-20 boats so far, plus dozens (hundreds?) of brokerage listings, in my own quest. Some have been lovely but more than I wanted to spend. Some have been reasonable prospects, and they've whispered lovingly in my ear, but thoughtful reflection helped me understand that there were enough reasons to make "walking away" the right thing to do. Hardest one, so far, was the perfectly lovely fresh-water 32-3 I found on a lake in Montana. Would have written a check that day, but it would have cost more than 25% over the cost of the boat to get it to my waters. VERY hard to walk away, but... it didn't "make sense" to do it.
We all have different priorities, some want a project, some want a deal, I mainly want to get back on the water, in a boat that sails well and makes me smile. And I want to not have boat payments or big-ticket issues hanging over my head and diluting my enjoyment. That helps me clarify my thinking when (for example) checking a boat for delamination or wondering how soon I will have to replace a motor, or facing the prospect of significant structural repairs.
I'll know the right boat when I meet her. Seeing a variety of boats - and really thinking through the pros and cons of each is what gives me confidence in that.

Edited to add, after reading the survey doc I'd concur with others, there's nothing there that I wouldn't expect to find in a 30-year-old boat. It if is an accurate and complete depiction, and assuming the engine/mechanical is sound, it doesn't look like there are huge "projects" looming... just all the normal projects involved in rehabbing, upgrading and maintaining a boat. There will unquestionably be work to do (cleaning, debugging/refurbishing systems, re-rigging, wood care, sails, etc, plus all the pleasures of tweaking things so she's set up the way you like), but.... it doesn't "appear" to be a boat that needs major repair.
Of the items in the survey, I'd probably pay a little extra attention to the water incursion at the portlights. rebedding the portlights is a common need, and not a huge job, but if enough water has come in that interior wood has been compromised, that can be a bigger deal.
Next steps to consider might include paying to have a rigger do an aloft inpection, and a good diesel mechanic to inspect and evaluate the engine. In my own quest, if I found a boat that I was seriously interested in - but had some questions about - I'd rather write a [relatively] small check and get an education, rather than write the big check and find out I bought a headache.
