Value From An Expert You Can Trust
About Scientific Valuation
At Scientific Valuation, we know a property appraisal is more than just a number on a page — it’s clarity for your next step, security for your future, and peace of mind when life brings big decisions.
Meet the Chief Appraiser – Clay Edwards
As founder and chief appraiser at Scientific Valuation I started this company as I saw too many home owners get stuck with an advisor that didn’t know how to write a defensible, credible real estate appraisal that would stand up to scrutiny in court or against the IRS.
With a decade of experience in property valuation in the PDX. I personally make sure every appraisal is backed by empirical market data that is defensible and credible. Every opinion and conclusion is backed by verifiable market data and logical reasoning.
When you work with me, you’re not just getting an appraisal report — you’re gaining a trusted guide who’s here to answer your questions, break down the appraisal process in plain English, help you feel confident with your decisions and protect your family.
I’ve been a contractor, a lender, a seller, a buyer, a property manger and an investor in addition to being an appraiser for a decade in PDX. Wearing different hats allows me to see real estate from different angles that other advisors might miss. I’ll analyze your property like it was my own.
I’m a real estate nerd, call me and let’s talk markets, construction, or finance. Let me know how I can help you with your situation.
