Editor's takeOptimal Blue ranks first among 10 tools in this category at 9.1 overall. Its dominance as the industry system of record, locking roughly 40 percent of US mortgages, is unmatched among pricing engines. The clearest risk is legal, with an active antitrust lawsuit over its Competitive Analytics tools.
How accurate is Optimal Blue's pricing engine?
The company claims a 99.995 percent accuracy rate for its compliant pricing, though some user reviews note it is not always fully accurate and can need manual verification.
Is Optimal Blue facing legal action?
Yes. A class-action lawsuit alleges its Competitive Analytics tools may allow lenders to coordinate pricing, a claim reported by HousingWire and still working through federal court.
