About Mike Certo
Branch Manager · Cornerstone First Mortgage · NMLS #260555 · Phoenix, Arizona
The short version
I'm Mike Certo. Branch Manager at Cornerstone First Mortgage in Phoenix. NMLS #260555. I originate physician + medical professional mortgages across Arizona — Mayo Clinic Phoenix attendings, Banner Health residents matching their first year, HonorHealth dentists, Tucson UMC fellows, AZ veterinarians starting practice.
We built this for Arizona's medical professionals — state-specific depth on eligibility, contract-based closing timelines, and the AZ employers and neighborhoods where physicians actually buy. Here you'll find Mayo Phoenix's physician-friendly landing zones, AZ counties' property-tax variations, which AZ employers have streamlined verification, and AZ-specific timing for residency-
What you should know about working with me
- Direct line. Not a call center, not a rotation. You text or call me at (480) 296-6513 and you get me.
- No commitment to apply. Initial conversations are educational. I'll tell you if a different program fits you better.
- Closing fast. Standard close 25-30 days. Match Day-timed closes can be 18-22 days when needed.
- Compliance-first. Cornerstone is regulated under NMLS #173855. Everything I publish + every loan I close follows program + state requirements.
- No "sales pitch" voice. Physician loans aren't right for every situation. Sometimes conventional jumbo wins. Sometimes VA wins. I'll tell you honestly.
My focus
After working a broader mortgage practice for years, I narrowed in on AZ physician + medical professional mortgages because the depth required to do them well doesn't fit a generalist approach. There are too many physician-specific factors — Redwood Sequoia program limits, residency contract timing, student loan IBR vs standard repayment, manual underwriting flow, AZ-employer-specific patterns. Each has cost physicians real money when handled by lenders who aren't paying attention.
