John Jakubek recommends Guy Rivera

Retired Human Resource executive

My son and our family trust were equal co-owners on a residential property. Recently my son and daughter-in-law requested to 'buy out' the family trust so that they held 100% ownership of residence. We initially worked with Bank of America on this endeavor which proved to be a real challenge for all involved. Their process was quite complicated and lending requirements were very difficult for a young couple trying to purchase their first home. After many, many weeks of assurances that things were moving in the right direction, BOA did not approve the loan. At the suggestion of a highly regard realtor in my area my son and daughter-in-law reached out to Guy Rivera at Guarantee Mortgage. Not only were Guy and the GM team extremely responsive they also made the process simple and straight forward. Within a few weeks time my son was approved and the transaction completed. Since that time I have decided to apply for a mortgage with Guy & GM and my experience has also been extremely positive. Having purchased several homes previously I can say without a doubt that this has been the best service and support I have experienced. Thank you Guy and the entire GM team.

Scott Turner recommends Aisling Ferguson

Aisling once again hit it out of the park in terms of the incredible service she provided in getting us a mortgage for our new home. She deftly helps everyone navigate a very complicated system, and is tenacious in solving any obstacle that might get in your way. Don’t think about going anywhere else for a mortgage. She’s the best!

Wes Herman recommends Guy Rivera

Multi time Client of Guy

I am a retired SB County, Fire Dept. Captain living in Goleta, Ca. I wanted to refi my home and was subjected to unbelievable technical and paperwork complications when I submitted applications to several national lending institutions. I finally found Guy Rivera, at Guarantee Mortgage. I could tell right from the start that business would go well with him. His personal attention to every detail and every question I had was really impressive. Guy was able to guide me through the process and complete my financing so easy and rapidly that we became friends. I recommend Guy to everyone I know who needs mortgage financing.

Nicholas recommends Rich Polonsky

Rich Polonsky was amazing throughout the entire process. Before the formal process of getting approved for the loan started, Rich explained every step and fee/cost to us so we would be as comfortable as possible. When it came time to get approved, there were no surprises because he did such a great job explaining everything to us and making sure we were prepared. There was never a time we felt like we were bothering him. Regardless of if it was morning, day, or night he was happy to help. Buying a home is stressful and having Rich on our team mitigated much of that stress. I would never work with anyone but Rich.

Karan Ramchandani recommends Sean Maley

CEO


Sean is amazing! I've worked with Sean over the last 2 months to get a loan for a 2 bedroom condo, my first purchase, in SF. He helped us along every step of the way, patiently explaining and re-explaining each of the mind-bogglingly complicated steps in the process of getting a mortgage loan.

Sean is the BEST communicator I know. Nearly every time I called him over 2 months, he either answered immediately or called me back within 1 hour. His email response times were phenomenal. He is personable, easy going, competent, and follows through on every request.

Pick him.

Darolyn Davis recommends Ken Dean

I would recommend Ken to anyone who is seriously looking for a home loan. I have worked with Ken on several home loans. He has made this daunting process so much easier. He is efficient, thorough, patient and helpful. He’ll tell you exactly what is needed and guide you through every step along the way. Most importantly we will find you the best most cost efficient loan available. I really appreciate the fact that he will shop around to find the loan that finds your needs.

Aisling was able to find a loan for a difficult and complicated project that had a critical deadline. Two other lenders were unable to do it. I am so happy we found her! She was fast, communicated throughout, and even fun work with.

Real Estate Agent with Zephyr Real Estate

I just closed a deal with Aisling Ferguson. I have been selling real estate for 20 years and working with Aisling was one of the best experiences I have had. She is extremely diligent and professional. She is focused on the client's needs and offered a high touch level of service. I never had to wonder about the progress of our clients loan as she was prompt to respond to questions and kept me well updated throughout the process. I hope I have the pleasure of working with her again in the future.

Sean consistently offered support through our new home purchase. He was accessible and always prepared for our (numerous) questions.

I appreciate his follow through and his attention to detail made the home purchase process fairly simple to navigate.

Allison Hyde recommends Kathy Derangi

Bilingual Resource Teacher

We called Kathy for help with a refinance that we need for a remodeling project. Kathy sprang into action immediately and walked us through every step with meticulous attention to detail. She found us a 30-year fixed at a better interest rate than we previously had. Kathy was always available and responded immediately to our queries. Thanks to Kathy's hard work, we were able to accomplish our goals before taking off for a long trip.

Connie Jaremczuk recommends Alan Kirth

Product Manager

Alan was crucial in helping me with financial strategies to expedite my transition from Redwood Shores to San Francisco. His advice went way beyond the home purchase. I totally followed his advice and was able to sell my home, purchase a new home in the competitive San Francisco market, and mov—all in less than 60 days. It was important to me to complete this transition as soon as possible. Without him, this transaction would not have happened as quickly as it did. I’m very grateful for the guidance of his experience and completely relied on it . Thank you Alan!!!

Chrystal recommends Julie Malta

First-time home buyer

Julie was everything we could have asked for in a loan officer and more. She made sure that she and her team very thoroughly went through each step of the process with us, and expertly worked with our realtor to secure our first home. As first time homebuyers we had lots of questions, and Julie was always there to answer and explain every angle. She definitely goes above and beyond the call of duty. She extraordinarily competent and she is just fantastic to work with on all accounts. Everyone on her team was also excellent throughout the whole process. I would highly recommend her and will look forward to working with her again if/when we decide to make another move!
