This person is trying to rip you off.
The collective value of their stuff is around a grand.
Vintage V132 $549 brand new, $300 used
Little Martin $300 used & discontinued, was $429 new
Boss Katana $229 brand new, $150 used
Dean AXS Mahogany Dreadnought $199 brand new, $130 used
Washburn Bella Tono Vite $299 brand new, $200 used
Snark Tuner $20 brand new, $10 used
Chromacast gig bag $30 brand new, $20 used
Straps and Capos maybe $20 each new, usually thrown in because so cheap
So for $2500 you can buy this character's leftovers, or you could buy all that stuff literally brand new with warranties and take your family of four to Disneyland with the grand you have left.
Or you buy it all used and have close to $1500 left for a really nice guitar, or amp, or whatever.
Either way, while this person might be a decent human being in some other aspects of life, they're trying to cheat you on this.
You deserve better.
