About John P

As a Mortgage Originating Manager in Southwest Florida (Naples, Marco Island) and the South Jersey shore, I work seven days a week to provide unmatched customer service and accessibility to the real estate community. My 30+ years in in the real estate business has allowed me the opportunity to really understand what customers want and need in a mortgage loan officer, wherever they are buying a home.
I began my career as a real estate agent for 10 years in Ocean City, N.J., where I was a former director of the Ocean City Board of Realtors as well as Vice Chairman of the Upper Township Zoning board. This gave me the unique ability to understand the real estate/mortgage transaction from start to finish. I found success in the mortgage business for several reasons but most notably my extensive product knowledge for complex self-employed borrowers, construction, and jumbo lending, as well as first time home buyers. I am so thankful for my terrific customers who made my career gratifying as I have been recognized with various production awards.
My goal is to make purchasing a home a seamless and smooth experience and to provide customer service that is not just the best, but also memorable. Let’s connect today!

Mortgage Calculator
This simple purchase mortgage calculator is an illustrative tool to help you estimate what your monthly mortgage payment could be when shopping for a home. You can adjust your loan amounts, interest rate and loan term to see how much your payment might change. It’s important to know that your specific interest rate will depend on your overall credit profile including your credit score, income, and debt-to-income ratio (the sum of all of your debts and new mortgage payment divided by your gross monthly income). I am happy to help explain the details and all the different product options we have available so you have a more definitive idea of how much house you can afford.
