Most of what we do comes down to one habit. We run the numbers on a house before we get attached to it.
That means the taxes the county will actually assess rather than last year's bill, what the repairs will actually cost at today's contractor pricing, and what the house sells for in a slow month. We would rather talk you out of a weak purchase than earn a fee on it.
We work a small geography on purpose. Collin, Dallas, Kaufman and Rockwall counties are close enough to drive in a morning, which is the only way to know a street rather than a spreadsheet.
