Hi Victoria,
I think this is not a real listing. Or- if it was a real listing at one time, it has sold. If you click on the listing detail link, it takes you to a Postlets Ad (an auto-posting service) that is an ad for "many available" homes in the area. The photo has a caption of "sample". I can't find anything that looks like this that is a recent sale or listing in Mount Vernon - but perhaps another Trulia respondant will find something on it.
Trulia doesn't always catch the non-listings because it is so automated. For actual, live listings, check on a good real estate site that is updated regularly. The search feature on my site is updated every 15 minutes.
Good luck and feel free to contact me for more property information in Skagit County. - Sat Sep 12 2009, 10:51
