Congratulations on your new boat! Wish you a lot o fun and great winds!
I am just starting looking for boats and although I have been looking for "older(cheaper)" boats, I am having the same problem you state, it is quite rare the sellers do share the problems the boats have.
As I am looking for early 00s boats (like 10 years old), I do expect them to need some investments in maintenance
of fixing, even substituting something.
The prices reflect the age, but sellers won't share what you should expect to be fixing on the next 6 months/ one year from buying
