I paid $20,800 for a 2016 26' JayFeather (26bhsw). The retail price was nearly $29,000 (including shipping to California). Options including : Outdoor kitchen, sway command, enclosed underbelly, electric tongue jack totaled nearly a grand.
I would think an asking price would be below $15,000 but I'm just comparing length, age and options. I'm not an expert by any means.
