Gian is excellent. He kept me completely informed on how my loan was progressing, and offered insights about the process. I received the same stellar service from Gian's team as well. A VERY special shout out to Veronica, who went out of her way to help keep my insurance agent, escrow company, and Prosperity on the same page. With the need for two insurance companies for my house, Veronica choreographed the needed steps to get my deal done, and without delaying the closing date. She's aces in my book! Thank you everyone for all the hard work!

⭐️⭐️⭐️⭐️⭐️ My husband and I had the absolute pleasure of working with Gian as we purchased our first home, and we truly cannot say enough great things about him. From start to finish, Gian was patient, knowledgeable, and incredibly supportive. As first-time homebuyers, we had a lot of questions—and even more questions we didn’t know we should be asking. Gian took the time to walk us through every step of the process, always making sure we felt informed and confident in our decisions. His calm demeanor, expert guidance, and responsiveness made what could have been an overwhelming experience feel smooth and manageable. Gian genuinely went above and beyond for us, and we’re so grateful to have had him on our side. If you’re looking for a mortgage broker who is not only a master of his craft but also deeply committed to his clients, look no further. Thank you, Gian, for helping us make our dream of homeownership a reality!

What is your home worth?

Check current market values for your home and view buyer demand.

I'm here to answer all
your mortgage questions

  • Do I need to save for a 20% down payment?

    No! With FHA loans you can get approved for as little as 3.5% down, VA and USDA loans can offer you $0-down options, and with Private Mortgage Insurance (PMI) you can get into your new home with less than a 20% down payment. Whatever your situation, you have options.

  • Are Pre-Qualification and Pre-Approval the same thing?

    No. Pre-qualification and pre-approval are two different things. Pre-qualification means that a mortgage lender has reviewed your financial records and believes you will qualify for a loan. A pre-approval is a conditional committment from a lender that they will lend you the money for a mortgage.

  • What's the difference between an adjustable and a fixed rate mortgage?

    A fixed rate mortgage means that the interest rate is set when you take out the loan and will not change. With an adjustable rate mortgage, the interest rate may go up or down after a certain amount of time. Many adjustable rate mortgages will start at a lower interest rate than fixed rate mortgages.

  • What is Private Mortgage Insurance (PMI)?

    Private Mortgage Insurance (PMI) is a type of insurance you may be required to pay if you are taking out a conventional mortgage with a downpayment that is less than 20% of the home's overall value. If you refinance your home with a conventional loan and your equity is less than 20% of the home's value, you may also be required to pay PMI. Private Mortgage Insurance protects the lender in the event that you stop making payments on your loan.

  • Can I access my home equity before I finish paying off my loan?

    Yes! Your mortgage advisor can help you find the right refinance and reverse mortgage options to help you access your home equity before you've finished paying off your loan. This can help with covering the cost of remodels, college tuition, long-term care plans, and more! Talk to your mortgage advisor to find out how you can access your home equity to cover any of your life's needs.

  • What do I do if I can't afford my mortgage payment anymore?

    The first thing you should do in the event that you can't afford your mortgage payements anymore is reach out to your lender. An experienced mortgage advisor can help you find options, such as refinancing or restructuring your loan, to help you keep up with your payments. Always reach out to your lender to ensure that you can keep up with your payments and stay in your home.
