True. But, that may be why it sold for $19,900. Hard to compare a typical lot to acreage pricing. I see where you are heading and good point but kind of not comparing apples to apples.
Back in the day I was involved in a transaction in Seagrove with 5 acres for 15 million. 3 million an acre. So today $340K an acre is looking good. I have rarely seen a buyer ask me how much that lot is per acre unless I am showing property/acreage in rural areas. $19,900 is a good buy for a lot that you can build one house on in Pt. Washington. The fact it is pending tells me so.
You can't compare 30A to Point Washington. Of course, our School board paid $100K/acre for unimproved land with no legal access in Point Washington, so you can always find someone who thinks something is a value (well, maybe not these days...)
I agree that someone thought it was a good deal. I understand that most people don't think of 'per acre' costs, but when you are trying to compare the value of two lots, and they are in the same area, the size of the lot (along with amenities, whether or not the tap fees are paid, etc) is part of the equation. That is, if you are buying with your head.
I worry that these small lots will lead to tower houses, which I know that people fought before in PW. I also worry that people will think "Well, you can get lots for $19K in Point Washington now" unless you understand the SIZE of the lot that sold.
