Frequently Asked Questions
How is the suggested price calculated?
It starts from the original price, applies a condition multiplier, reduces value for age, then adjusts up or down based on current demand for similar items.
Should I always start at the suggested price?
It's a good starting point for negotiation. Many sellers list slightly above the suggested price and expect to negotiate down toward the low-end estimate.
Does this work for online marketplace listings too?
Yes, the same logic applies whether you're pricing for a driveway sale or an online listing like Facebook Marketplace or Craigslist.
