About Tatyana

I got my start in the mortgage industry in February 2001 as a loan processor/loan originator with a full service brokerage company in Edmonds, Washington. Since then I worked with a few mortgage lending organizations, including Washington Mutual, Response Mortgage, Financial Advantage Home Loan Center, HomeStreet, and for the last 8 years - Absolute Mortgage before joining CornerStone as a Senior Loan Officer.

I am very excited to be part of great organization such as Cornerstone, and enjoy the variety of options to meet my client’s financial needs. Cornerstone provides a wide range of home loan programs and competitive interest rates. We finance first-time homebuyer’s, FHA, VA, Conventional, High Balance, Jumbo, HELOCs, and portfolio loans.

When a client starts a home loan application, I love listening and getting to know the big picture of their overall financial situation, so their home loan will fit their long and short term goals, which is unique for every person. I value each and every client, and strive to win their trust for life.

The greatest compliment is returned business from my clients, their friends and family, and from my business partners.

I had the pleasure of working with Tatyana Sineeva as a realtor, and I am delighted to provide a glowing review of her services. From start to finish, Tatyana displayed exceptional professionalism, efficiency, and expertise, making the homebuying process a breeze for both me and my client. Tatyana showcased outstanding communication skills, prompt in responding to inquiries, keeping all parties involved well informed and updated on the loan progress. She worked diligently to gather the necessary documentation, coordinate with the underwriting team, and ensure that all deadlines were met. We were able to close transactions smoothly and on time, which is crucial in real estate. I wholeheartedly recommend Tatyana to anyone in search of a top-notch lender. It was a pleasure working with Tatyana Sineeva, and I look forward to collaborating with her again in the future. Mara Hoja, Realtor Charleston, SC 843-437-9760

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.
