What Nantucket County’s 2026 limit means for buyers
At $1,249,125, Nantucket County’s one-unit conforming limit runs $416,375 — about 50% — above the $832,750 baseline that applies in standard-cost counties, and it matches the national high-cost ceiling: the most a conforming loan can be anywhere in the contiguous U.S.
In practice, that means a buyer here can finance a home up to $1,249,125 with a conforming conventional loan — at conforming rates and guidelines — where a buyer in a $832,750 county would already need a pricier jumbo loan. Cross above $1,249,125 and Nantucket County buyers enter jumbo territory too: expect higher credit and reserve requirements and lender-specific underwriting.
FHA buyers in Nantucket County get the same $1,249,125 one-unit ceiling — well above the $541,287 FHA floor used in low-cost areas. And because the multi-unit limits reach $1,599,375 for a duplex and $2,402,625 for a fourplex, a small multi-family in Nantucket County can often still be financed conventionally — an edge for house-hackers and owner-occupant investors who can count projected rent toward qualifying.
Bottom line: in Nantucket County the conforming/jumbo dividing line is $1,249,125, not the $832,750 you’d see nationally — so a higher-priced home here may still qualify for a conventional loan. Confirm your exact figure below before you shop, since limits reset every January.
