REVERSE MORTGAGE

What Sets Us Apart

Getting a mortgage is a big deal. Your choice of a mortgage lender should be too. Guarantee Mortgage has a well-earned, established reputation. Find out why we’re different, and why that difference will matter to you.

Why use a Mortgage Banker

What are the benefits of using a mortgage banker?

Unlike a bank, which is limited to offering you mortgages from its product line only, a mortgage banker can offer you multiple loan options from multiple lenders, many of which you’d likely not have known about.

With so many confusing mortgage options and offers to choose from, and with the constant refrain of “Lowest rate! Lowest rate!” echoing across the Internet, it’s no wonder many homebuyers choose to work with a mortgage banker who has the ability to shop your loan request to many lenders locally and nationwide.

CLIENT REVIEWS

Gordon did an incredible job with my first home purchase! As a single, small business owner with massive student loan debt, I was anxious about my chances of finding a place in a competitive housing market. However, Gordon’s knowledge, thoroughness, responsiveness, and patience made this process refreshingly smooth and worry-free.

From my first phone call to the closing of our refinance I appreciated Eric’s professionalism; his knowledge and quick response are top notch. He answered every call, text or email timely and explained our options. It was a pleasure to work with him!

The refinance I had to do was complex and large amount (for me). We started the process at beginning of year and of course the pandemic struck. It slowed everything down and throughout it all , Aisling kept me updated and remained accessible, patient and informative. We recently got the new loan approved ! Thank you so much Aisling!

I’ve done about 5 refi’s with Joel and he comes through every time with the best rates. He takes the time to explain everything and is dependable, trustworthy and easy to work with. I love his no fee approach. I highly recommend him. I’ve had many friends use him and they’ve all said the same thing.
