Jane, looks like it’s overpriced, the house across the street is listed for $74,xxx. Also, there’s a large pile of tree debris in one of the pictures. Did a tree fall and cause damage? It’s almost 50 yrs old, and right on the water; hard to tell from the pictures of fresh paint if it has really been kept up from inevitable weathering. And there is no mention of “park approval” to lease the land, or of the monthly fee. The listing screams “inexperienced seller” which can lead to troubles, though not if the buyer is saavy.
Most likely, the owner died, and heirs turned it over to a management company to “clean up and sell.” Not having done a good comp analysis, they have listed it too high. I’ve seen that scenario play out a few times where I live. Usually they sit on the market until the listing expires, then a new realtor lists it at a comparable price and it sells inside of a week.
