How the limits are set
Conforming limits come from the Federal Housing Finance Agency (FHFA), which adjusts them each year based on changes in the FHFA Housing Price Index. FHA limits come from HUD: the national floor is $541,287 (65% of conforming baseline), the ceiling is $1,249,125 (150% of conforming baseline), and counties between are calculated as 115% of the area median sales price.
Multi-unit and house-hacking math
Martin County 2-, 3-, and 4-unit conforming limits are $1,066,250, $1,288,800, and $1,601,750 respectively. If you're house-hacking — owner-occupying one unit of a 2-4 unit property — these are the limits that matter, and the rental income on the other units can be used to qualify. FHA and VA both finance owner-occupied 2-4 unit properties at their own multi-unit limits.
