Well, Ronnie, I kinda have to agree with you. We're a bit surprised about the recent prices too. That said, "value" is in the eye of the purchaser. All I can say is that our lot appears to be "worth" quite a bit more now than we have invested in it. And, we didn't buy it as an "investment."
More to your point regarding resort amenities and costs, here's a brief rundown. First, what you are seeing in the lot prices reflects more than just raw land cost. They all have utilities (water, sewer and electric) installed. Most include significant improvements such as high-capacity (8* thick, reinforced) RV parking slabs, stamped concrete surrounding surfaces, underground propane tanks, full outdoor kitchens, patio areas with propane fire pits, etc. A few have some type of shade coverings for the RV as well.
There is a $140 per month HOA that covers common-area maintenance, water and sewer service (electric is paid by the lot owner), WIFI, daily garbage pick-up service, mail service (including private mailboxes) and more. Lot landscaping is either maintained by the owner, or done by a contract landscaper. And, of course, there are those pesky property taxes collected by the county.
I suppose the "value" of owning such a property depends on the viewpoint of the purchaser/owner. And, in the past few weeks at least, it seems like purchasers are seeing value in their eyes. We bought our lot back in 2016 and did so because we liked the area and the people in the resort. The ability to come here whenever we wanted was a value for us, as was being able to configure our space exactly as we wanted to. We have, periodically, rented our lot out when we were not here and received a fair amount of income. I think that is coming to an end for us as we want the freedom to have the lot available for our use whenever we want it. And, to some extent, having had a couple of renters this past summer that did not respect the property is reinforcing that decision. Rental use always comes with increased maintenance issues.
So, that's my best effort to answer your questions. Are the properties at Polson worth the price being asked? Only a potential purchaser can assess that.
