Wenatchee market really has two markets. If your price range is $325-350,000 or less it is around 120 days including funding. Higher price more like 180. But inventory is low and sales are up so well prepped and priced properties are 60 or less.
Average days do vary based on exact location, pricing, condition, size, schools, etc.; if interested in any specific area, do consider working with an agent of your own; he/she can provide any necessary information so that an informed decision can be made.
It depends on how you calculate it, but around 70 days. You should be discussing these thing with your agent, however & if you do not have one, I would be happy to refer a good one to you. It is free, after all. Just let me know. Also, if you need to get approved for a loan, just let me know. I can do that as well.
