We had an absolutely amazing experience with Cornerstone Home Lending. From start to finish, their team was incredibly responsive and always available to answer our questions. They really took the time to understand our personal circumstances and worked hard to find the best package to suit our needs. The entire process felt seamless and stress-free, which is saying a lot when it comes to mortgages! We genuinely felt looked after every step of the way. I would highly recommend Cornerstone Home Lending to anyone looking for a knowledgeable, supportive, and efficient home lending service.

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.
