Now, that doesn't mean that every agent will negotiate their commission... some are firm and hardfast, but others will. It all depends on their burden rate, and what services they offer.
As others have suggested, interview several agents and ask them what they charge, and what services you can expect for that fee.
ALL commissions are negotiable.
Interview a few agents.....ask them for a written marketing plan, and at that time they will discuss their commission structure.
Depending on the market in Port Jervis; the rate may less important than the marketing and services the agent you hire provides. When interviewing Realtors this is what I'd be questioning them about. I'd also want to know how many transactions they've closed in the past year and what the average amount of those transactions was.
Good Luck to you!
