Amy Sullivan recommends Larry Horowitz

Just refinanced with Larry once again. I believe this is the 3rd time! It went great. Larry has so much patience for this complicated process. My family has been working with Larry for over 20 years. My brother, my sister and my parents all have had great working relationships with him. We highly recommend Larry!

Rod Hemphill recommends Kathy Derangi

Kathy took over for a colleague, helping me complete the refinance of my home. She was there for me every step of the way with all the information I needed when I needed it. It was a pleasure working with her.

Rod Hemphill recommends Debra Stedt

Ms. Stedt has guided me through the complex processes of buying and refinancing my home, helping me get the best loan rates, explaining the process in easily understood terms, and making the process as painless as possible. She has been a great resource and I will highly recommend her to anyone.

Will Hudson recommends Bart Welles

President, Vx Capital Partners LLC

Bart is a conscientious and well-informed mortgage broker. He has represented my wife and I on three different home financings at this point. Getting a home loan involves lots of structure-options and lots of paperwork these days. Thankfully Bart knows his markets well and when it comes to documentation, Bart and his team shoulder a lot of the drudgery of the application process. I recommend Bart.

Caitlin McGinty recommends Guarantee Mortgage

Realtor at Marshall Realty

If you are looking for a lender, you need not look further than Mark. As a Realtor, I have worked with many lenders throughout transactions and no deal has gone smoother than when I worked with Mark. Not only is he completely qualified and knowledgeable on all things loans and mortgages, but he is also in constant communication with you and your clients. My clients always felt safe and taken care of which is incredibly important when the stresses of home buying arise. I guarantee that you will have a successful transaction (and a fun one!) when working with Mark.

Masto Somlith recommends Guarantee Mortgage

Registered Nurse

We recently collaborated with Mark Harris from Guarantee Mortgage to do a cash-out refi on our home. We were so impressed with his attention to detail and constant communication. And the best part, he was able to refinance our home into a 15 year loan, from 27 years remaining, get us a substantial amount of cash out, and only increase our payments slightly. We didn’t even know this would be an option! He gave us multiple scenarios with clear explanations helping us to make the right decision for our needs. We are now able to use the extra money for remodeling projects and pay off credit card debts. We have been recommending him to all our friends and family. Mark is truly an awesome guy. Thank you again Mark for making this experience very easy. The turn around time was incredibly fast. Looking forward to working together again very soon.

Bryant Hofstadt recommends Guarantee Mortgage

Health Technician

We recently had the distinct pleasure of working with Mark Harris from Guarantee Mortgage to refinance our home. We were nervous since our previous experience with home financing was complicated and confusing. Mark made this process seamless. He was very professional, attentive, easy to reach, and friendly. He answered all our questions and put us at ease. We would highly recommend Mark for anyone looking to buy or refinance their home. He is truly a great guy and very knowledgeable. Thank you again Mark for your patience and efforts. We are extremely grateful.

Sharon Higgins recommends Guarantee Mortgage

Artist and resident of San Francisco

My husband and I had a very positive experience working with Mark Harris. Buying a new home is a complicated and stressful process, and he made the day-to-day intricacies as simple and clear as possible. He was very communicative and available to answer all of our questions. Mark never made me feel as though my questions or concerns were unimportant. He provided options on types of loans in an effort to get us the best deal possible and walked me through the pros and cons of each. He worked quickly, efficiently, and with great dedication on our behalf.
When my husband and I re-finance down the line, we will absolutely be going through Mark. I highly recommend him. You won't find a friendlier or harder working loan agent than Mark Harris.

John lee recommends Guy Rivera

Wealth Manager

I recently changed from 28 years as a W-2 employee of 3 different major brokerage firms, to an Independent 1099 self -employed financial advisor. As difficult as it was to convince a lender to take on a borrower with a new status, Guy and the crew dug deep, pled my case and made my mortgage happen!! Way to go Guy(s)!! Thanks a million!!!

Julie Liang recommends Kathy Derangi

Kathy was a joy to work with throughout our home buying process. She was extremely responsive and was critical to helping us exceed our already tight timelines. We were initially set to close on a Monday, but Kathy helped us line up documents and fielded lender requirements, such that we were able to close on a Friday (providing us with an extra weekend to prepare for our move). I would not hesitate to work with Kathy again.

Julie Liang recommends Debra Stedt

Debbie was a pleasure to work with throughout our home buying process. She was extremely responsive and prompt, both essential qualities when the SF real estate market demands competitive offers with short (basically as short as possible) escrow periods. I was so impressed with her ability field and filter questions from our lender, such that it was easy for us to provide supporting information to push our transaction through. She anticipated issues, asked for supporting materials with enough lead time, so that we weren't stressed out or rushing as we approach the end of our closing period. I recommend Debbie without hesitation and would use her again for future transactions.

Marta Perez recommends Christopher Baker

I’m so impressed with Chris Baker professionalism; I would recommend him without hesitations. His responsiveness, to our questions and multiple emails was outstanding. His work ethic is amazing, always responds, day or night, even on weekends always give us details at every stage of the process. He is the best person to have in your side when you are working with multiple agents, and companies. Chris is the best at what he does he becomes part of the team.

Joe and Jennifer Reyes recommends Guy Rivera

We found Guy's name in the local Independent paper which offered a discount for local educators. Guy is a very positive and upbeat consultant. He explained the mortgage process thoroughly and in terms that we understood. The whole process was very easy and pain free. We were able to obtain an excellent loan with so many credits to the closing costs. We highly recommend Guy and will be using Guy the purchase of our next home with his award winning personality and knowledge.

Paul J Andreini recommends Christopher Tyeskey

Senior Real Estate Agent / Keller Williams SF

PHENOMENAL is the adjective I now use to describe my experience with Chris Tyeskey. Along with his wife Cecelia Tyeskey of Guarantee Mortgage they made an escrow I recently had SEAMLESS. My clients nearing retirement age had never owned a home and needed direction from the lending side. Having spoken with three lenders for their own diligence, and still uncertain, it occurred to me that Chris was familiar (family) with the Sacramento market where they wished to move from San Francisco. From the first phone call, Chris was constantly in contact with us every step of the way. Cecelia was very educational to my clients having never been through the process. This can be an emotional flight for people and the drama was kept to a minimum for them because of guidance by C & C. NOTHING happened without them knowing what to expect. The same week of closing I had a client closing through their Wells Fargo with a very similar situation. Watching both lenders perform was interesting. Wells Fargo was like a ping pong ball of drama, while Chris and Cecelia came in for a dramtaic-free smooth landing. They are NOW my #1 source for my clients. I proudly display their rate sheets at my open homes. PHENOMENAL, simply a PHENOMENAL duo. Not to mention as individuals they ROCK! Call them, don't even hesitate. Did you know they do their own funding! Bless them!

David Simoni recommends Ben Swan

Director of Sales

I highly recommend Ben! Ben is an absolute expert in the field and his experience really came through. Ben was very communicative so not a day passed when i did not know the status of my loan. I found Ben to be very honest and upfront about all the pro's and con's of different approaches and really guided me to the perfect loan to fit my situation.
Thanks Ben!

Nicole Ayaz recommends Kathy Derangi

Attorney

Kathy was the consummate professional with a wonderful human touch. This can be a stressful process and Kathy helped alleviate that stress by keeping us informed every step of the way. She clearly communicated what was needed on our end and was quick to follow up. Her experience clearly showed. She was an absolute delight to work with.

Christina Wenger recommends Debra Stedt

Library Director

I highly recommend Debra Stedt. She is incredibly responsive, answering questions within minutes via email. Debbie is patient--even if you ask the same question a hundred times!--and a very good explainer. She takes her job seriously, recognizing that she's not simply organizing information, but helping her clients understand the financial choices they're making. This is my third home purchase, and this loan experience was by far my best.

Amy recommends Debra Stedt

Realtor

Debbie did a fantastic job to help my buyers secure their home loan and close earlier than anticipated!

Taylor Davis recommends Kathy Derangi

Director of Legal

Kathy was a pleasure to work with - first and foremost, she is very responsive and very diligent, which means that the little details that are critical to closing a deal don't get lost. I received a home loan with Kathy's assistance for the first time this year (after having done 4 or 5 transactions in the past) - and this was by far the best service I had ever received, Kathy and her team were by far the most competent loan consultants I have ever worked with, and I would absolutely use Guarantee Mortgage again (in the past I have found myself talking directly to loan underwriters to move things forward - I didn't have to do that once with Guarantee Mortgage and, in fact, Guarantee Mortgage anticipated in advance issues and questions that would come up and, as a result, we never had any issues). I'd highly, highly recommend Kathy.

Taylor Davis recommends Debra Stedt

Director of Legal

Working with Debbie was an absolute pleasure. This was our 5th home loan transaction and Debbie's customer service and ability were far and away the best we had received. Debbie is extremely proactive and extremely responsive. There is no waiting around for a response from Debbie and it is never hard to get a hold of her. And usually when I had a question or issue, Debbie had already addressed it. She also is able to talk with sellers and sellers' agents in support of bids in a competitive market. I'd highly recommend her - she is awesome!

Anatoliy Pavlishin recommends Aisling Ferguson

Product Manager

Aisling is awesome. i've worked with her for the past 13 years in various capacities. She is always thorough, accurate, and puts her clients first. It is a privilege to use her as a mortgage broker and know that she will deliver on her promises.

Beatriz Rincon recommends Robin Patronik

CFO

Miss Robin,

She has been very professional, effective, and clear about procedures and process to follow. The refinancing process is every day more tedious and documented, and she was very patient and able to guide through some challenges during this long process.

Jeanne Kearsley recommends Aisling Ferguson

CCSF Instructor

I worked with Aisling on my original home loan and a recent refi. Both experiences were extremely positive. Aisling is focused, diligent and yes fast talking--but that just indicated to me how quickly her mind is working in my best interest! I was impressed by her efficiency and the response time to any of my emailed questions, usually within 10 minutes! I would highly recommend Aisling to anyone interested in making a real estate investment.

Randall Choy recommends James W. Argo

managing Partner, Hedani,Choy,Spalding & Salvagione, LLP

Jim took a difficult refinance, with difficult clients, and came through with flying colors, allowing a challenging family law and elder abuse case to settle, by refinancing a property to equalize the distribution of property between the parties. Highly recommended for his expertise, creativity, and professionalism. Dealing with multiple parties, and 5 attorneys, was incredibly challenging, and Jim successfully navigated these "shark-filled" waters.

Minaksi dave recommends Aisling Ferguson

Management Consultant

Aisling is a super efficient and timely service provider. She helped us with our home loans from ensuring we received a competitive rate to stepping us through the process of loan docs and ensuring at all times we had the data to make the right decisions. She is very through and quality minded to ensure a successful completion. I would always recommend Aisling and the fact we do not go anywhere else for a loan is a testament to that.
