Good with caveats

Yes, but water will be the challenge. Wells run deep, near 610 feet, so budget $20,000 to $44,000 for one. The growing season runs about 291 frost-free days, long enough for a spring and a fall garden. Flood zones cover parts of the county, so look up any parcel on FEMA's flood map before you offer.
