A lender that my husband and I had worked with first gave me Chase Costello's information. I called the next day and was able to reach Chase immediately. He was so personable and easy to talk to. I explained what my husband and I were looking for and he took the time to write down all the things on my list that were important, and told me he wanted to be able to address all of my concerns I had with buying a new house. Once we started going to see houses with Chase, I felt he had our best interests at heart. Some realtors we had worked with in the past, felt too pushy and abruptly brushed off certain

Chase is truly the best Real Estate agent I've EVER worked with! My first experience with him was when I moved from Florida to Washington! Obviously I had to be prepared to make a quick decision but Chase set everything up SO well! I landed on January 12th! On January 13th, we saw 10 properties with 10 more set for the next day! It wasn't even necessary! We had an offer in on the 13th, a signed contract on the 14th and closed on the 31st! Who else can make that happen? Now we're looking for a small getaway place! We have been over most of the Western part of the state! He's

When we decided to sell and make a cross-country move, we were overwhelmed with all the details that had to be sorted out. The timing on selling our house was critical, and we needed someone we could trust to get it done. A friend of mine recommended Chase and Maria, saying they worked very hard for them in purchasing their home in a very competitive seller's market a couple years back. Chase and Maria made me feel very comfortable, listening carefully to what we were trying to accomplish, and sharing the details of the strategy they thought would work best. Our house sold in a difficult

Working with Chase Costello and The Costello Team was an excellent experience with both selling my home and purchasing a new one. The up-to-date knowledge and advice on preparing my home for sale were invaluable. They definitely persevered with a difficult buyer to get my home sold. I had planned to buy a home in a very particular area, but once Chase learned what type of home I like, he suggested a different area which I ended up falling in love with and purchased in. I would never have considered it otherwise. I am extremely happy, and I can't recommend Chase and his Team highly enough

We used Costello & Costello to rent a home after relocating to Seattle. If you understand the challenges of moving to a new state with zero knowledge about an area, and having to find a new place to live for you and your family, you'll appreciate how important this is. What made it so this important to me and my family was that we could not find a single agent that would show us around. All the agents we contacted either declined, were too busy or had the audacity to want to be paid up to $300 per day to look for a rental. Chase Costello volunteered to look for a rental on the night

Chase Costello and team is great to work with. I've requested for a tour through the site for a property I felt was close to our requirement. In less than a minute (not kidding) I got a call from Crystal to fix the time and I was at the property in less than an hour. Chase helped us out the offer together for the house. He is not too pushy and provides guidance based on your views. It was strong offer but sellers decided to wait for longer. Finally we bagged the offer. What's amazing about Chase is, his persistence and constant follow up with selling agent and us. At some point we dropped

I have worked with Jeff Costello for about 12 months to find a place in Issaquah. Jeff has been extremely patient with me as I looked at about 25-30 homes over this period. He always make himself available for showings; is on-time; knowledgeable about the prospective home before we look at it and from my interactions is a really good bloke. I just secured a great place and I look forward to working with Jeff in the future.

We live in another state and wanted to sell our condo quickly. Chase Costello was exceptional to work with. He helped us determine which repairs and updates were worth doing, and which wouldn't matter. When it was time to list, even though it happened to be over a holiday weekend, he held an open house and skillfully negotiated multiple offers well over asking price. Long story short, we had two buyers drop out of escrow (no fault of ours or Chase) and he was able to get us back on the market immediately, and two MORE times, we had multiple offers over asking price in just a day or two. But

We really enjoyed working with Chase to find a place to rent as we moved to the area. He put together a packet for us to review before touring the homes. The packet was comprehensive and very helpful to review prior to coming to the area. Chase was also very responsive and clear in his communication. He added a bit of humor, which we appreciated. He was a good listener and we plan to go to him when we look to buy later this year.

Recently, and after very short notice, I found out that I'd be moving up to the Seattle area after my husband received a great job offer. The home searches began with such intensity and through a Zillow inquiry, I was put in touch with this real estate company.
We were under the impression that they knew how to work with people who are new to the area. I couldn't have been more wrong. The associate who had originally responded to our inquiry made it seem like as soon as we arrived, they'd have a number of realtors that could show us around.
Fast forward to the day before we were

My husband and I recently purchased a property with the wonderful assistance of Jeff Costello and his team at Costello and Costello Real Estate Group. While searching for a realtor, I was drawn to the firm's user-friendly website which allowed me to search hundreds of homes each day. We chose Jeff Costello because of his prompt response to our inquiries, his caring and down-to-earth personality and vast knowledge of the real estate industry. We found the perfect home, but knew there was some very fierce competition for the property. Jeff crafted an offer that got us the place of our dreams

Chase and Jeff are phenomenal Real Estate Agents that work hard for their clients. I have had the pleasure of being a part of helping their clients buy a home with providing Mortgage advice. On numerous occasions the Purchase Price they fought to get their clients was below the appraised value. These guys are great negotiators and have demonstrated time and time that they fight hard to make sure their clients' get a great deal.
