"Maybe... Lots are generally small enough that it might be hard to make the case for an marginal utility argument that a larger lot brings less. I've seen more than one person buy 2 lots to build only on one, but wants the extra buffer. In Bella Vista Village, they frequently pay retail for 2 lots only to use one lot to build and one to site a larger septic field on, rendering it a surplus lot. But it started out as excess. "
So are you suggesting that people will pay MORE for the 2nd lot because it's value as a buffer is higher than its value with a separate use?
All RE is local so I would never say never. I'm pretty sure it wouldn't work out that way in my region. I've seen lots of examples of SFR buyers buying 2 parcels for the one house - they often straddle the lot line but not always. What I don't see is those transactions selling at higher pricing than other assemblages purchased for individual development.
Well, I should take that back - I have seen industrial zoned assemblages selling for more than the values of their individual component pieces. You can't always find industrial tracts near highway access that's large enough to support a 400,000sf distribution warehouse - those parcels sometimes have to be "built". Same with some of the redevelopment activity occurring in the urban areas where they want to build a 50-story building.
