Matt DeLine and his team of professionals go above and beyond what is needed to secure the deal, whether it’s the buying or the selling of property. My Wife and I are completely satisfied with the outcome. We have used Matt’s services twice. Once for selling my Brother’s house, and once for purchasing our dream house. We are going to work with Matt and his team again to sell my Dad’s house. I would personally recommend Matt DeLine to anyone needing to buy or sell property.

We have worked with Matt for many years, and from the beginning we understood why Matt was so highly regarded in the industry. His tenacity to get his clients across the finish line is bar none. What makes Matt unique is his ability to anticipate ‘could be issues’ that aren’t even on the client’s radar, or they would know to ask. You’d be hard-pressed to find a more skilled and knowledgeable and top notch negotiator Realtor than Matt. He is wonderful to work with when you’re considering or selling or buying your home.

I can't recommend Matt highly enough. He is a consummate professional and was able to sell my Dad's house for well above market. He was also able to help the renter (who was residing in the house prior to the sale) find new housing. Matt is an all round good guy and he's highly effective at his job.

5 Stars are not Enough! Working with Matt DeLine was fantastic! At the time, my husband and I were going through a very difficult time, and selling our home was very traumatic! Not only was Matt extremely respectful of our situation, he helped us see the positive side, and led us through the transition with grace and ease. The process was so painless it was remarkable! Besides being truly professional, he did his due diligence and completely immersed himself in our home, spending hours at the City of Encinitas learning all he could about our specific situation, making sure we uncovered every possible stone in case there was an opportunity for us to keep our home. I would highly recommend Matt DeLine!!! 10 Stars +

Buying a house or condo is not easy and we had a lot to learn. We did buy a property from Matt and he was always available to answer our questions and responding promptly to our calls. Matt and his team held our hands through the entire escrow process. Matt made what could have been a stressful process as easy as possible, and always communicating with professionalism.

Matt DeLine did a wonderful job selling our home under very challenging circumstances! Not only was the home a Probate sale, there was a Renter and the COVID-19 pandemic hit during the time of sale. Matt was able to professionally handle the staging of the home, including accommodations for remote viewing and socially distanced walk-thrus. He kept in close contact with the lender, who was struggling with the extra work-load caused by the COVID-19 crisis. Matt DeLine performed fantastically, and my family and I were delighted with the outcome! Thank you Matt!!

Matt DeLine is all that you could want in a realtor - and more. He went out of his way with an "out of towner" seller to oversee the complete preparation of our house for sale, including cleaning out furniture, books, garage junk, etc. and then getting painters and repair people take care of getting the place ready for viewing. He oversaw replacing the carpeting and arranging for outside gardening and some corrective painting. I cannot speak highly enough of Matt DeLine as a person to work with. In a word, he is GREAT!

I was going through a tough probate situation, still mourning death of a loved one, having to deal with legal matters, and needing to sell a property quickly. Matt was a blessing. He took a great load off my shoulders. I quickly learned to trust him completely. He is as honest as they come, he does what he says he'll do, and he's a communicator. You never have to wonder what's going on; he'll keep you updated. Experience was totally successful. Thanks Matt.

In a probate matter for which I represented the administrator, Matt DeLine handled all the details of a sale of a house in El Cajon. He was knowledgeable and great to deal with overall. He and his crew sold the furniture and furnishings, cleaned the premises, and sold the house for more than the probate referee's appraised value. I highly recommend Matt for real estate sales throughout the county.

We had a great experience working with Matt and would highly recommend him. Matt helped us purchase and close 3 homes at the same time. He was pleasant, organized, efficient and to the point. He did a fantastic job throughout all negotiations and continued follow through after the sales closed. (on time) 5 Star and Highly recommended!!
