I don't know anything about Coxsackie except that I bought a dog from a breeder there years and years ago. Great dog.
You might want to look at Delanson real estate listings. Delanson is in Schenectady county but I see some Albany County listings on the sites as well.
I think Delanson is sort of a catchall name for a bunch of rural and semi-rural areas to the west of Albany.
You're likely to get a chance at a little land there.
Generally, I think, anywhere in Delanson would be 30-40 minutes to Albany.
