Not sure how you define ‘small’, but of the dozen or so
DVC brokers Fidelity (
https://www.fidelityrealestate.com/brand/disney-vacation-club/) is currently the second largest. According to the search engine I use, there are 2689 DVC resale listings, Fidelity has 452 of them - 16%. The largest broker, the site sponsor, (
https://www.dvcresalemarket.com/about-us/) has 791 listings - 29%.
I’ve never read that Fidelity was known for underpricing their listings, so I compared their current BLT asking prices to the largest broker, Fidelity is asking $145 - $182 for BLT,
DVC Resale Market is asking $142 - $210 for BLT.
I assume brokers/agents suggest list prices to sellers, but that ultimately the seller decides whether to follow the broker’s advice & how high or low they want to list at, but I’ve not sold any of my contracts so
