I'm surprised there's even a question of RV/boat storage in driveways having an effect on property value. It's an inarguable fact that property (and neighborhood) values take a hit when there are RVs and boats stored in driveways. Tell me potential buyers looking at 135 Ashcat aren't going to be affected by two boats being stored in neighbor;s driveways - one of them chocked with firewood and the trailer tongue sticking out in the sidewalk.
Or how about the people on Turnpike near Faithorne who are storing their pop-up camper on the grass in their front yard? Is that OK also? No effect on prop values?
I love nature, rec and family time. I also have a pop-up that I store in my garage. Many of my neighbors have boats (one of them 21') and all manage to keep them in their garages. Sure, I have my pop-up out front for a couple days after camping (you know, loving nature, rec & fam and all that) to clean it out etc. But I put it back in the garage afterwards. I understand the need to have a boat/RV out every once in a while but permanent storage on the driveway is wrong in many ways.
@asbestoshills: I am one lucky guy, absolutely. Thanks for noticing and for reminding me!
