I’m Celeste Sierra—a wife, mom, mortgage professional, and breast cancer survivor. My work is about helping people navigate a major decision, but my life and my purpose reach beyond a loan closing.
Over 31 years in mortgage financing, I’ve learned that people need room to ask questions. Whether you’re buying for the first time or returning to the market after many years, I want you to understand the conversation and feel comfortable participating in it.
My own breast cancer journey has made faith, family, and community even more meaningful to me. Giving back through THE Breast Cancer Fundraiser is one way I turn that gratitude into action.
Meet the woman behind the Geek ↗You don’t need every answer before you reach out. Whether you’re ready to move or just figuring things out, we can start with your questions.
Let’s talk through your budget, down payment questions, and the steps between browsing and buying.
Talk about buying ↗Considering a refinance? We can review your goals and discuss the costs and tradeoffs before you decide.
Review your situation ↗Self-employed? Buying an investment property? Unsure where to begin? Let’s discuss what information we need to explore your options.
Ask your question ↗A home loan is more than an interest rate. Your down payment, monthly payment, available savings, income, and plans for the property all belong in the same conversation.
We start by understanding those pieces. Then we can discuss what information is needed to review your options, what questions remain, and what next steps fit your timing.
If something needs preparation, I’ll explain what we need to look at. If you’re ready to move forward, we’ll discuss the application and documentation process so you know what comes next.
Before you fall in love with a listing, let’s talk about a payment you would feel comfortable managing. We’ll discuss the purchase price alongside down payment, closing costs, property taxes, insurance, and any applicable mortgage insurance or association dues.
Pre-approval involves a review of your financial information. It’s a useful step in preparing to shop, but final approval also depends on the property, underwriting, and other loan conditions.
A refinance deserves a closer look at both the potential benefit and the cost. A lower monthly payment can come with a longer repayment period or other tradeoffs, so the right question is whether the whole picture fits your goal.
Tell me whether you’re hoping to change your payment, use equity, or review your current financing. We can identify the information needed to evaluate that next step.
Your income, goals, and timeline help shape the conversation. These are a few of the topics we can explore together.
A little more geek knowledge: click or tap a card to turn it over.
Program availability and eligibility vary. A conversation is the first step, not a guarantee of approval.
My approach starts with listening. I want to understand your goals, explain the moving parts in plain English, and help you feel informed about your next step.

We start with a discovery conversation, including Zoom, to get to know each other and talk about your goals.
We review the information needed to discuss your options and identify questions or next steps.
Ready now or planning ahead, you’ll have a clearer idea of what to work toward.
Before you put that buyer on hold, let’s have a conversation. I can help you understand what needs a closer look and what your buyer may need to work on.
My Realtor partner portal gives connected agents real-time updates on their leads and files. If we aren’t connected through your own CRM, it offers a shared place to follow the buyers we’re working with together.
Use the sign-up link below to get connected to my Realtor partner portal. Want to learn how we can work together, discuss a buyer scenario, or see how the portal fits your workflow? Schedule a Zoom with me and let’s walk through it.
If you already know you’d like to apply, you can begin directly in my YourMortgageGeek smart borrower portal. It’s the place to start your mortgage application online.
If you’re still deciding or want to talk through your situation first, reach out to the Geek. We can discuss your questions before you begin.
The application opens in a new tab on my YourMortgageGeek smart borrower portal. Starting an application does not guarantee approval.
You don’t need a perfect file or all the answers. A few notes can help us make the most of our first conversation.
Let’s plan your next step ↗No. We can start with your goals and timing, then talk about what you might want to prepare before you’re ready.
Absolutely. Tell me about your situation, and we can discuss what documentation may be needed to explore financing options.
We talk about what you’re trying to accomplish, your questions, and the next steps for reviewing your situation. It’s a chance to get to know each other, too.
