What I Can Do for You

Mortgage solutions,
tailored to your situation

Every borrower is different. Whether you're buying your first home, refinancing, or need a jumbo loan, I'll find the path that fits your goals and budget.

First-Time Home Buyers

Down payment assistance, low-down-payment programs, and step-by-step guidance so you never feel lost. The process is simpler than you think.

Refinancing

Lower your rate, shorten your term, or cash out equity. I'll run the numbers honestly and tell you whether refinancing actually makes sense for you.

Learn more

Jumbo Loans

Conforming loan limits won't cover it? Jumbo loans handle larger amounts with competitive terms — and I'll help you navigate the extra requirements.

Learn more

FHA & Conventional Loans

FHA loans for flexible credit, conventional for the best rates — or a side-by-side comparison so you can choose with confidence.

Learn more

Rate & Term Analysis

Not sure if now is the right time? I'll pull current rates, compare scenarios, and give you a straightforward answer — no pressure, just clarity.

Learn more

Pre-Approval Guidance

A solid pre-approval strengthens your offer and gives you negotiating power. I'll walk you through exactly what lenders look for and how to present your best case.

About Katie

Your mortgage journey deserves a real person behind it.

Hi, I'm Katie Yerkes Diaz. I've spent my career helping families and individuals in the Oak Lawn community navigate one of the most important financial decisions they'll ever make — and I know how overwhelming it can feel without clear guidance.

As a loan officer with CrossCountry Mortgage, I work with a wide range of loan programs — from FHA and conventional to jumbo — so I can recommend what actually fits your situation instead of pushing a one-size-fits-all solution.

My approach is straightforward: I listen first, explain the options plainly, and only move forward when you feel confident. No jargon, no pressure, no surprises at closing.
