  • J & L helped me buy a home

      We met Jon and Leslie by chance when we started looking for a house in Castro Valley and we could not have been more fortunate in finding a realtor team. Jon and Leslie were relentless in their pursuit of a suitable home for my family. We were at a very competitive price point and the demand for houses far exceeded the availability. The Fosters had to work extremely hard to help us determine good competitive bids while not overbidding too high. They talked us through bidding strategies and various scenarios for each property we were interested in and did an exceptional job in presenting our offers to the sellers. From locating houses to look at through the offer process to close of escrow their professionalism and commitment to our purchase was exemplary. I highly recommend when you are ready for your next East Bay real estate transaction that you give the Fosters a call. You will not be disappointed!

      • J & L helped me buy a home

          Jon & Leslie helped us purchase a single family home in Castro Valley and this is the best buying experience I've had in the bay area. Buying a home is stressful but Jon & Leslie eased the process in everyway... Here are a couple of standout things they did: - Jon was always available to hop on a call whenever I was stressed out regarding the loan process. He was patient and always provided a reassuring yet balanced view. -We were constantly connected/ accessible on WhatsApp and they patiently answered every question I had was regards to the documentation ( usually after 10pm since I had to put my son to bed) - I was stressed about finding a pre-school for my son with the move and Leslie provided me with a list of schools and reviews about them from Castro valley moms club!( Who does that?!?) -Jon recommended movers, a concierge service to get utilities transferred and the list goes on... If you are looking to do anything real estate related- look no further. 5 star experience!!!! Jon and Leslie always listen, never push, are very non judgemental and are wonderful human beings and pride themselves in doing a great job! Here's a quick timeline of events: May 1: we had our initial call with Jon. He took copious notes on all our preferences and patiently listened to me blab about my requirements for almost an hour! ++ For great listening skills! May 2-28: Every weekend, Leslie would pick out 4-5 different homes and show it to us. With each weekend, Leslie was able to narrow down based on our responses to the homes we viewed. Interestingly, Jon had shared every detail from the call with Leslie so I never felt like I had to repeat myself. May 26: Leslie contacted me saying she had seen this house that she thought we might like so I went and saw it on a weekday. I fell in love with the place(Leslie nailed it!!) and had my husband view it the following weekend ( when 100+ other folks were also viewing). We loved it and put in an offer. June 1: We got into a multiple bid scenario but Jon and Damien(lender recommended by Jon) worked their magic to get our offer accepted! 45 days later we closed!!! Thank you Jon & Leslie!!

        • J & L listed and sold my home

            My wife and I meet Jon and Leslie while we were looking for a new home. We decided to not only buy the house they were selling, but we had them sell our townhouse. Jon and Leslie were always available sat down with us and gave us pros, cons and analytics on the home and area. Never have I felt so confident and at ease while buying a house. As a sales person with two decades under my belt. It never felt like I was being sold to. They are honest, easy going and enjoy helping turn people's dreams into reality. Highly recommend.

          • J & L helped me buy a home

              Jon and Leslie, are an amazing duo. We first met them over 4 years ago while purchasing our home in Castro Valley. They represented both sides per sellers request and really did amazing job doing both. They have excellent follow up, very knowledgeable and always available. We decided to use them again when selling our other home. To this day, they still check in on us and I recommend them to anyone looking to sell or buy.

            • J & L listed and sold my home

                Jon and Leslie were incredible to work with! As a first time home buyer, they were instrumental in helping me navigate the daunting task of purchasing a home. My wife and I bought a home from the bank and I'm certain we would not have been able to get such a great deal if not for Jon and Leslie. They went above and beyond my expectations. This husband and wife team are extremely honest, personable, knowledgeable, and above all else, hardworking! I can't thank them enough for their help! I highly recommended using them!

              • J & L listed and sold my home

                  Jon and Leslie have helped us sell and buy our homes. They are extremely professional and very knowledgeable on the markets. They were able to get us top dollar for our home and help negotiate a great price for your brand new construction home. They were very detailed and always responsive with call and emails.

                • J & L listed and sold my home

                    Jon and Leslie have always been our go to agents. They have helped us on a couple of transactions. They do a great job of making sure to keep you updated throughout the process, you can always get ahold of them if you have a question or unsure of how something works. They truly are a great team and good at what they do.

                  • J & L listed and sold my home

                      We chose Jon and Leslie as our realtors from among dozens of local agents in our town because of their polished marketing presence. They did not disappoint. We had high expectations, and they exceeded them all. With J&L, you not only get two expert realtors who work together seamlessly, you get their very strong team. From photography and marketing to staging, doc management, and negotiating, every aspect of the process was first-rate. Excellent division of labor. Best of all, we received a large number of offers for our home, including the winning bid, which was 23% over our asking price. Jon and Leslie are straight-shooters, who run a very transparent process and are easy to work with. Couldn’t have asked for more. glennjoy99

                    • J & L listed and sold my home

                        Jon and Leslie were an absolute pleasure to work with. Their expertise and experience in the East Bay is truly unmatched. We truly appreciated their level of detail every step of the way. They have a wonderful team that are there with you whenever you need. Whether you’re buying or selling with Jon and Leslie, you can rest assured that you’re in great hands as you make one of the most important transactions of your life.

                      • We recently worked with Jon and Leslie on a 1031 exchange that had a few extra challenges outside the normal complications of this type of transaction. I appreciated their ability to think outside the box as we needed to get creative in order to make this exchange work. From start to finish, this transaction was handled professionally, even with when it looked like things could easily fall due to circumstances outside of our control. I would definitely work with Jon and Leslie again and appreciate their dedication to their clients and our community.

                      • From the first time my wife met Leslie, she knew that Jon & Leslie were true professionals. They listened, explained what service they could provide, and then, performed as promised. How often does that happen? It did for us! I'm convinced it will for you, too.

                      • I've had the pleasure of working with both Jon and Leslie for years. They are responsive, dedicated and always striving to deliver top level service. Jon always takes my calls when I need real estate advice and I trust what he has to say is always looking out for my best interest. I know I could recommend Jon to anyone and he would treat them the same way he treats me, like family.

                      • My husband and I had a bomb dropped on us when we were given 62 days to move out of our long term CV rental with 2 kids, a 55 pound dog, and a cat. We did not think we were in a financial position to purchase a home, but reached out to the Fosters to check things out. Jon was helpful and assured us that he would work hard for us despite our limited budget and extremely tight time frame. He and Leslie accommodated our schedules showing us homes late in the evenings. They responded to countless emails from me immediately with answered questions and feedback to my thoughts. Within these 2 months, I was impressed with the existing relationships the Fosters had with the listing agents of the homes we viewed. Jon reached out to other real estate agents he knew asking if they had any homes coming onto the market that would met our needs. In the end, this is what was successful. Jon found us a home prior to it going on the market; he and the listing agent were able to negotiate between the two of them. We settled on a very good price for the home without any hassle. It was exactly 60 days from the time we contacted The Fosters to the time we got our keys. My husband and I were told so many horror stories about purchasing a home and I am happy to say that this was a smooth, exciting, and enjoyable process for us. My family is ecstatic in our new home and we have the Fosters to thank for this. I would highly recommend using them for your home buying/selling purposes!

                      • My experience with Jon and Leslie Real Estate Group was just amazing. We're Chinese and my dad wanted to buy a home but he had difficulty with his English skills so, I'm his son and I did most of the English portion for him.Jon Foster is a fantastic real estate agent and for a first time impression, he sold me on being the guy that I can immediately refer to. It's like he really cares about you and he'll constantly go to the extra length to help you get what you need.During the open houses and when Jon and my family finally meet, Jon is incredibly patient, respectful, and welcoming when listening to my parent's description of their ideal house. He is very knowledgeable about the home and background and demonstrated it by talking about the changes in the area and what happened back then. He's like a historian and I found it interesting, learning about the area that we're not familiar from.Jon's replies and responses are pretty quick. He'll get back to you within a few minutes to a few hours; mostly within a day. For emails, its the same thing but sometimes I have the misfortune of not seeing it and it gets lost under my junk mail. My fault on that part.Jon's negotiation skills is just phenomenal; he got us almost a month of extensions just to help us get the house when we were having issues and the sellers were not very happy. To get into details about how that happened, it all started when my family was still looking for a house, I get an email from Jon one day, suggesting a house that we might be interested in and within our budget. I showed the house to my parents and they immediately wanted to get it because the amount of space and price was just perfect. After telling Jon that we wanted that house, he helped us right away; he helped us make and offer and win the bid while staying close to our budget. During the paperwork and the transfer of funds, we had complications and difficulty with our original bank lender that it was like they were trying to sabotage us. While we were dealing with our bank problems, Jon helped us get an extension in a total of 4 times. It was when for the 3rd time, we were fed up and left our bank and Jon recommended us a guy that he trust for home loans. I'm surprised he was able to help us get almost a month's worth of extension due to our bank's mishandling. Our new lender helped us get a new loan and within like 1 and a half week, we got our house.I highly recommend Jon and Leslie Real Estate Group. They stuck with us through thick and thin, well beyond the selling date, and got us the house we wanted by some miracle. I can't thank them enough for all of their hard work and commitment working with us.

                      • Jon and Leslie helped us research, find, and negotiate the lease for a new commercial space for our small business and we could not have had a better experience! They were knowledgeable, responsive, and an absolute pleasure to work with. Highly recommend working with their top notch team!

                        - Bridgett Galli
                      • I worked with Jon Foster on the sale of my parents house in Castro Valley. Everything was handled smoothly and efficiently! He worked with us via long distance as I had just moved my parent to the Sonoma County area (which is 75 miles away). My parents had lived in this home for 56 years. Jon interacted with them with great respect, sensitivity and dignity knowing it was difficult for them to let go of their home.The process from start to finish was quick and easy. Jon coordinated all the inspections, assisting in finding a well qualified buyer, provided a great referral to an estate sale company, and arranged for a timely close. My parents and myself couldn't have been happier with the professionalism and integrity of Jon and Leslie Foster and their support team. If you want your home to be priced fairly for a quick, smooth sale with Real Estate Agents you can trust and depend on Jon and Leslie Foster are the best of the best!
