Why use Shaun?

Vicki Mathews

Realtor, Capstone Ventures inc
Buyers Agent – Silverdale WA

Shaun is a professional who takes his work very seriously but is also very personable. He is on top of a transaction from start to finish and goes the extra mile to make sure that everything runs seamlessly. He stayed my main point of contact and was always reachable. He was honest, clear and concise from beginning to end.Shaun did a fantastic job and I’m excited to work with him again.

Sarah Eichhorn

Realtor, Kitsap Real Estate Group
Listing Agent – SIlverdale, WA

Prompt communication, closed on time, and pleasant on the phone. He worked for the buyers, I was on the listing side. and There were no surprises. I have nothing negative to say, communicative and reliable. If I see an offer with Shaun attached I know what to expect as far as communication and timeliness which speaks volumes.

Shelby Vance

Realtor, Realty Station inc.
Buyers Agent – Bremerton, WA

The client could ask Shaun questions whenever they had one, he was there, and willing to answer all of mine as well. The transaction went smoothly, he was very friendly and personable, the clients felt they were in great hands!

Rico Jose

First Time Home Buyer
Bremerton, WA

Went through Shaun and his team when buying my first home, couldn’t ask for a better loan officer. He made the process smooth and easy, always kept me updated on the best rates. Shaun made sure everything met their deadlines to prevent any delay in the loan process. On top of that always took the time to update myself on the current status, in which my opinion is very a substantial factor. Will definitely be coming back to Shaun again for future home purchases.

Susan Mayer

USDA First Time Home Buyer
Port Orchard, WA

As a first time home buyer with ALOT of questions and uncertainties about the entire process, Shaun Guerrero and his team at Fairway Mortgage treated me like family. I was welcome to call or come to the office ANYTIME I had questions, which I did almost daily, and they always took the time to explain everything so I could understand it. It was such a pleasant experience that I have been recommending Shaun and his team to anyone who is thinking of buying a home

Nichole Petersen

First Time Home Buyer
Bremerton, WA

I would say that Shaun has a calm way of walking his clients through what can be a very stressful process. He made the steps clear and made sure that I understood what was needed of me. I knew the timelines for each step in the process, and he was able to explain the portions that confused me. Shaun made this such a painless process. He walked me through every phase of the process with confidence and thorough explanation. I felt completely informed at all times. I didn’t know where to start with this entire process, and Shaun made it easy from start to finish. I already have him in mind to recommend for any friends that are looking to buy a home

Chance Petronave

USDA First Time Home Buyer
Poulsbo, WA

Shaun was great! When we decided to buy our first house we didn’t really know anything. Shaun walked us through the whole process and made sure we knew exactly that this was what we wanted before we even started the search. I cannot express enough the gratitude Valerie and I feel for the professional, caring and prompt attitude that Shaun showed us. Thanks buddy!

Tim Tremblay

VA, First Time Home Buyer
Bremerton, WA

Shaun Guerrero and his team helped my wife and I out so much as first time home buyers. They really did bend over backwards for us ensuring he got us into our new home in a timely manner with my wife who was 7 months pregnant. He worked weekends for us and he fit himself into our schedule to accommodate us and explained everything we wanted to know since we knew basically nothing. I would strongly recommend him and his team to anyone. In fact I already have!

Mike O’Neill

Shaun Guerrero and team were simply the best. My wife and I were unsure of the process and had a lot of questions. Not only did Shaun and his team answer the questions, they walked us through the process step by step ensuring we were aware of every step. Shaun and his team made this process simple and easy and I would recommend Shaun Guerrero to anyone that is need of Mortgage services. Thanks for everything Shaun!

Robert Earl Blankenship

VA Refinance Client
Tenino, WA

Easy to deal with and low pressure. Good professional, Every time I asked for information Shaun made sure I received the update or answer. The process was easy, but there were times I needed to resubmit forms and Letter Of Explanation multiple times. Again most likely due to underwriters.

Scott Ulrich

Refinance Client
Shoreline, WA

Shaun and his staff worked with us through multiple offers on homes through the last couple years. In the end we settled on a refinance of my current home, but when the time comes to move, Shaun will be the first call we make. Thank you for helping us through the process, we couldn’t have done it with you.
