About Jason

Ask Jason’s clients why they love working with him, and you’ll hear the same things. He always picks up the phone, he has a knack for creative financing solutions, and he never makes you feel like a number. Whether you’re buying your first home or investing in real estate, you’ll have a partner on your side ready to find the right loan for you.

For Jason, helping people find their way home is more than a career. It’s the family business. His mother was a real estate agent for over 35 years, and he works alongside both his brothers here at Cornerstone.

Outside the office, Jason enjoys hiking, attending live music concerts, and serving his community with Oakland Rotary. Passionate about music, he also plays drums in two nine-member bands, both with full horn sections. Married to Nati and proud dad to Leo and Sasha, Jason devotes his free time to making sure their orange tabby, Mishmish, is living his best life ever.

Fast and patient — a rare combination. Jason closed our jumbo loan in about two weeks as self-employed buyers, but what I valued most was that he taught me instead of just telling me. He explained every number, every option, and why one choice was better than another, so I understood my own loan by the end. Days before closing he found us a better structure — lower rate, no mortgage insurance, much lower payment — and walked me through both versions until I could see the difference myself. He didn't have to do that. Highly recommend Jason and his team.

Jason is the best. Caring and knowledgeable-most important is he follows through! Jason is my go to guy, and has helped on multiple transactions-I would not use anyone else, and I’m a banker!

Where do I even begin?! Jason, thank you for once again patiently navigating all my twists, turns, and ever-changing emotions throughout the loan process. I’ve worked with you many times, and somehow, you continue to outdo yourself every single time. Your expertise, patience, and dedication are truly unmatched. Thank you for always going above and beyond! I know I am not the most emotionally level headed when it comes to myself and you really hung in there. Thank you

This is my second loan with Jason Wizelman at Cornerstone Home Lending — and he made it feel like working with a trusted family friend. From our first call he remembered details from my previous loan, asked the right questions about what my son and I needed, and recommended a plan that fit our timeline and budget without pushing anything unnecessary. Jason took care of the messy parts I dread: he reviewed and organized our paperwork, flagged a missing document before it became an issue, and coordinated directly with our real estate agent and the title company so I didn’t have to chase anyone. When a timing conflict threatened our closing date, he stayed on the phone that evening until a solution was in place. He explained rate options and closing costs in plain language, walked me through the numbers, and made sure my son understood what to expect at each step. What stood out most was how personable he is — he checked in with short, thoughtful updates (never long, confusing emails), answered questions quickly, and kept the whole process calm and straightforward. Thanks to Jason’s attention to detail and dedication, the refinance/purchase went smoothly and with zero anxiety. I wouldn’t hesitate to work with him again.

Mortgage insights

Helpful guidance for buying a home, financing your next move, and understanding your mortgage options.

Homebuying FAQs

Purchasing a home enables you to receive tax benefits while building equity that you can cash out in the future. Owning a home also gives you the opportunity to truly personalize your space.

Yes! Prequalifying first can help you save time and effort before you get too far into the process. You will know upfront how much home you can realistically afford. It also lets real estate agents and sellers know that you’re a serious buyer, which can be an advantage when making an offer.

Your lender will consider a number of factors when determining your maximum loan amount. Some of these include your debt-to-income ratio (how much of your monthly gross income goes toward paying debts), cash available for down payment and closing costs, and credit history.

Your loan officer will work with you to determine which loan product benefits you. They will review your current finances and future financial goals. Your loan officer will also consider factors like your target monthly mortgage payment and how long you plan to live in the home.

A fixed-rate mortgage has an interest rate and payment that stay the same over the life of the loan. With an adjustable-rate mortgage, the rate can either increase or decrease, based on market factors. The monthly payment can also go up or down based on the rate adjustment.

A conventional mortgage is a home loan that is not offered or secured by a government entity (like FHA or VA). Conventional mortgages typically conform to the loan limits set by the Federal Housing Finance Administration (FHFA) and are eligible for purchase by Fannie Mae and Freddie Mac (the two government-sponsored enterprises that guarantee the majority of mortgages in the U.S.).

Unlike government loans like FHA, VA, and USDA, conventional loans can be used for more property types (primary residences, second homes, and investment properties). In addition to the popular 30-year fixed conventional loan, there are also more choices for loan structure, including 15-year or 20-year terms and adjustable-rate mortgages.
