>Flaming Alamos were not visible on the outside of any of the homes, because the properties were clad in other materials. But the team asked Harp to assess - by looking at their style and exterior - if these properties were likely to have been built during a period when Flaming Alamos had been on sale. "We would basically take a screenshot of that house or residence and shoot it over to John and say 'would this house have these bricks inside?'" says Squire.

Zillow and tax assessors will list the age\year built of any property.
