She was very helpful during the entire process & gave us the right advise on all our questions. It was our first house we were bidding on & she worked with our agent to get closing reduced to 21 days from 28 which really made our offer competitive. We did not even have an underwriting done so closing in 21 days was most amazing service we can ever imagine.

Karen saved the day! Our previous lender made a last minute change causing us to look for a new lender 4 days into our 21 day escrow. Karen was able to get us approved and onto underwriting right away! We closed right on time and we couldn’t have been happier with Karen and her teams service. They were quick, responsive and extremely helpful throughout the entire process. I’ll recommend Karen and her team to anyone that is looking for a loan!

We had a somewhat unique lending situation but, unlike many of the other mortgage providers we spoke with during our loan search, Karen was able to quickly come up with a solution that worked perfectly for us. Additionally, she guaranteed and ensured a prompt close of escrow. It was so straightforward to work with Karen and I would absolutely advise anyone to at least consult with her while searching for a lender, and even more so those in atypical lending situations.

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.
