Helping you make informed mortgage decisions.
Castle Funding Corp. has been advising buyers and homeowners since 1989, helping more than 1,000 families across California navigate purchases, refinances, and long-term mortgage decisions. As a family-owned brokerage now led by the second generation, our focus has always been on clarity, preparation, and long-term relationships.
We take the time to explain options, compare scenarios, and help you understand the tradeoffs so decisions feel thoughtful rather than rushed. Whether you’re buying your first home or evaluating a refinance, you’ll receive the same care and attention we’d offer our own family.
How We Can Help
Whether you’re buying your first home or reassessing an existing mortgage, we help you understand your options so decisions feel informed and intentional.

How We Work
We believe good mortgage advice starts with clarity and preparation. Our role is to guide you through your options, explain tradeoffs, and help you make decisions that fit both your current situation and long-term goals.
-
Clear, competitive options
We compare loan options across multiple wholesale lenders so you can see how different loan structures and pricing actually compare.
-
Thoughtful loan strategy
Every recommendation is based on your goals, timeline, and financial picture -- not a one-size-fits-all approach.
-
A guided, coordinated process
One application, one point of contact, and a process that's clearly explained from start to finish.
-
Access to multiple lenders
As an independent mortgage broker, we're not limited to a single bank's products.
-
Transparency at every step
We explain the numbers and tradeoffs so you can make informed decisions without pressure.
-
Long-term relationships
Many of our clients return years later or refer friends and family because they value clear guidance and consistency.
Have questions about your options?
Your questions deserve clear, honest answers. We’re happy to talk through your situation and offer guidance — whether or not you decide to move forward with a loan.
