A Market With Only a Few Trades a Year
This is also why Alpine has no condominium, co-op, or townhouse sales or active listings in county data through March 2026, and why ZIP 07620 showed zero rental inventory as of the same reporting period. There is effectively one product type here: detached single-family homes on large lots. That narrows the sample even further, and a narrow sample is a noisy sample.
Days on Market Tell the Same Story
Three numbers, three different pictures of urgency, all describing homes in the same 6.4 square miles during overlapping months of the same year. None of them is wrong. Each is measuring a different, small set of closings, and in a market this thin, that is what "measuring the market" actually looks like.

What a 2.55-Acre Parcel on Route 9W Actually Bought
Sewer versus septic adds another variable to that math. Connecting to an existing sewer service area is generally simpler and less costly than designing and maintaining a private septic system, and not every Alpine parcel sits inside a mapped service area. That is worth confirming with the utility directly before treating any two lots as comparable on cost.

Frequently Asked Questions
Why doesn't Alpine have any condos or townhomes on the market? County data through March 2026 recorded no condominium, co-op, or townhouse sales or active listings in the borough, and ZIP 07620 showed zero rental inventory in the same period. The housing stock here is built almost entirely around detached single-family homes on large lots, which is consistent with Alpine's zoning pattern and its limited remaining vacant land.
