Every number on the map names its source and month. We only use data we're permitted to publish; we do not use Zillow data.

Linton Global Value Gap
The Value Gap asks one question: are local prices high or low relative to local incomes, compared with similar places?
- For each area, divide the median listing price (Realtor.com) by the median household income (ACS).
- Find the median of that ratio across all peers at the same level (U.S. states, Florida metros, Florida counties or Florida ZIP codes) for the same month.
- Value Gap = (area ratio ÷ peer median − 1) × 100.
A positive Value Gap means the area is priced high relative to local incomes; negative means low. It is a relative measure, not a forecast, an appraisal or a statement that a market will fall or rise. Listing prices reflect what's for sale, which can differ from what sells.
Linton Global Market Score
The Market Score summarizes market strength on a 0–100 scale. For each area we rank it against its peers (same level, same month) on six inputs, convert each rank to a 0–100 percentile, and average them:
- Population growth (higher is better)
- Median household income (higher is better)
- Listing-price growth, year over year (higher is better)
- Inventory change, year over year (falling is better)
- Median days on market (shorter is better)
- Linton Global Value Gap (lower is better)
An area needs at least three of the six inputs to receive a score. Because the score is relative, a 70 means stronger than most peers at that level, not a grade on an absolute scale.
Bank-Owned Real Estate (OREO)
OREO is other real estate owned that FDIC-insured banks report on their call reports. We total it for active Florida-headquartered banks and map it to the county where each bank is headquartered. The property itself can be located anywhere, so treat it as a signal of where distressed-asset holders are based, not where the properties sit.
Limits
Small ZIP codes may have too few listings for Realtor.com to report; they appear gray. Census estimates carry margins of error, especially for small areas. None of this replaces property-level due diligence, a broker's opinion of value or an appraisal.
