The Arizona mortgage banker who actually understands self-employed income.
A large part of our work involves helping self-employed Arizona borrowers qualify when traditional banks have already said no. Business owners, contractors, investors, and high-income borrowers often look far weaker on paper than they actually are. This site exists to solve that problem.

Mike Certo runs the Phoenix branch of Cornerstone First Mortgage, a full-service mortgage bank lending in 49 states. Because processing, underwriting, and funding are handled in-house, borrowers typically get faster communication and more direct accountability throughout the process.
Why we built this site
Traditional banks are built around clean W-2 income. Self-employed borrowers often reduce taxable income legally through deductions, business expenses, and reinvestment — which can make strong borrowers look weak on paper.
The alternative mortgage market solved this years ago. The challenge is finding a loan officer who actually understands how to structure it correctly.
Why this approach works better for self-employed borrowers
Instead of forcing every borrower into one rigid underwriting model, we work with multiple specialized lending partners that evaluate income differently depending on the situation. That flexibility matters for business owners, contractors, investors, and borrowers with complex income structures.
A bit about Mike
Mike Certo has spent more than two decades helping borrowers navigate difficult financing situations across Arizona and beyond. A large portion of that work involves self-employed borrowers whose real financial picture doesn't fit traditional bank underwriting.
His approach is straightforward: clear communication, practical strategy, and honest answers about what's realistic. No script, no salesy follow-up, no pretending a file fits when it doesn't.
What we won't do
- Push you into the wrong product because it's the easiest one for us to close.
- Push you into refinancing back to us later. If a different lender is better at that time, use them.
- Surprise-quote you with a rate that bears no relationship to what actually funds.
- Pretend a file works when it doesn't. If you're not ready yet, we'll tell you what would change that.
Frequently asked questions
Who is behind Self-Employed Loans Arizona?
Self-Employed Loans Arizona is run by Mike Certo (NMLS #260555), Branch Manager at Cornerstone First Mortgage (company NMLS #173855). We are a team, not a one-person shop, and self-employed and non-QM borrowers are most of what we do across Arizona.
Is Cornerstone First Mortgage a direct lender?
Yes. Cornerstone First Mortgage is a direct lender, which means we control the file from application through closing. Processing, underwriting, and funding happen in-house, so you get faster answers and one team accountable for the outcome.
How does the team help self-employed borrowers qualify?
We qualify you on your real cash flow rather than the income left after write-offs. Depending on your situation, we use bank statements, a CPA profit-and-loss, 1099s, or assets. We check whether a cheaper conventional loan fits first, then find the best alternative if it does not.
What areas of Arizona do you serve?
We serve borrowers statewide across Arizona, with most of our volume in the Phoenix metro — Phoenix, Scottsdale, Mesa, Tempe, Chandler, Gilbert, and the surrounding cities — plus Tucson, Flagstaff, and Prescott. We also help borrowers moving into Arizona from out of state.
Who we are
We are a Phoenix-based mortgage team led by Mike Certo (NMLS #260555) at Cornerstone First Mortgage. We focus on self-employed and non-QM borrowers across Arizona — business owners, contractors, investors, and high-income earners whose tax returns understate what they really make.
Self-employed financing is most of what we do, so we know the programs, the underwriters, and the structuring that turns a complicated file into an approval. We are a direct lender, so we control the process from application to close.
What we believe about lending
We believe you should not be punished for writing off legitimate business expenses. We qualify you on your real cash flow, not just the income left after deductions.
We also believe in telling you the truth. We start by checking whether a conventional loan is the cheaper path, and we will tell you when waiting a tax year, paying down a balance, or choosing a different program saves you money. No script, no pressure.
Stop fighting your tax return.
Send your real numbers — deposits, profit-and-loss, 1099 income, or assets. We'll tell you which qualifying approach may fit best based on how your income actually works.
