ForeScore: Measuring the Place Behind Every Mortgage

Traditional mortgage underwriting measures the borrower.
Appraisals measure the property. ForeScore measures the place in which they interact.

We define place as the evolving economic, housing, and demographic environment that shapes both collateral value and borrower behavior throughout the life of a loan. ForeScore delivers two forward- looking metrics at the ZIP code level, updated quarterly:

Default Risk Score

Quantifies how place affects the probability that loans in a given location will default.

Prepayment Risk Score

Measures how place influences the likelihood that borrowers willrepay theirloans ahead of schedule.
Both scores are standardized around 100 – par. A score of 80 in a given ZIP indicates conditions 20% more favorable than baseline; a score of 130 indicates conditions 30% less favorable. The adjustment is straightforward: apply the ForeScore deviation from par to your existing risk estimates, and your model immediately reflects the future location risks your portfolios actually face. Or, incorporate the data directly into your model for even better risk assessment.

What distinguishes ForeScore from other geographic risk tools is its orientation in time. Most available tools are descriptive; they tell you where defaults and losses have historically been concentrated. ForeScore is predictive. It forecasts local economic conditions forward over the full 30-year life of a mortgage loan, capturing not where risk has been, but where it is headed.
MORE FAVORABLE CONDITIONS
50 100 par 150
80 20% more favorable than baseline
LESS FAVORABLE CONDITIONS
50 100 par 150
130 30% less favorable than baseline
The result is a single, model-ready score per ZIP codethat integrates directly into existing PD, LGD, and pricing models — no software to license, no model rebuild required.

Independent Dimensions of Mortgage Risk

The most important question about any risk variable is whether it adds genuine information beyond what you already measure. ForeScore does, and the evidence is unambiguous.

The table below cross-classifies realized default rates by borrower credit score and ForeScore across 47,000 mortgage originations, with defaults observed over seven years. Neither variable subsumes the other; each explains variation the other leaves unexplained.

The practical implication is significant. As borrower credit quality declines, sensitivity to local economic conditions increases. For the weakest-credit borrowers in the sample, the same shift in local conditions that produces a modest difference among prime borrowers translates into a 15-percentage-point swing in realized defaults. This is precisely where additional information is most valuable and where ignoring place leads to the most consequential mispricing.

The commercial impact is measurable. In UFA's analysis of more than 30 million mortgage loans, incorporating ForeScore improved pool valuation:

ForeScore in Practice

Local economic risk touches every stage of the mortgage lifecycle. ForeScore is built for the institutions that manage it.

Portfolio Concentration Risk Management

Risk managers and chief credit officers use ForeScore to map geographic exposure across their mortgage holdings – identifying concentrations in deteriorating markets before delinquencies surface and before regulators ask.

Secondary Market Investment & MBS Valuation

Investors use ForeScore to assess the geographic risk distribution of loan pools at the ZIP code level, adjusting default and prepayment assumptions by location for more accurate pool pricing and capital allocation.

Loan Servicing & Portfolio Surveillance

Servicers use ForeScore's updates to identify which parts of their portfolio are in markets where conditions are weakening – enabling proactive intervention before borrowers miss payments.

Mortgage Insurance

Insurers use ForeScore to assess the geographic concentration of their insured portfolio, supporting more accurate reserve estimation and more disciplined underwriting in markets where local conditions are deteriorating.

How ForeScore is Built

ForeScore is built on a proprietary econometric model of local economies, updated regularly. The process integrates economic, housing, and demographic data at the ZIP code level into forward-looking risk scores across the full 30-year mortgage horizon.
