We cant say enough about Karls services. Hes very professional, knowledgeable,and responsive to communication. We felt like his only clients (even though he had others) because he attended to everything so quickly. It was obvious he always had our best interest. When looking at homes, he was sure to point out any issues we hadnt thought of, confirming he wanted to see us end up with a home that best suited us. It was the first time it was actually an enjoyable experience for us when purchasing a home because Karl went above and beyond, not to mention his wonderful sense of humor. It was stress free!

A few years ago we moved my Dad from upstate NY into our condo in Nashua. Needless to say, things were a bit cozy. After a years worth of fiasco's with real estate issues in NY, my Dads home finally sold and we were ready to find our dream home. I was a bit wary of real estate agents after the NY experience but along came Karl. Karl actually listened to what we needed and wanted in a home and didn't waste our time showing us places that wouldn't work. He was there every step of the way, answering questions, researching local areas and sharing various vendor information for all of our needs. The time and effort Karl put in went above and beyond anything we imagined. I can honestly say that this is the home we were meant to have, perfect in every way for my husband, myself and my dad. The fact that Karl showed the utmost respect to my Dad who is a WWII and Korean War Vet was heartwarming. The experience was so exceptional that we hired Karl to sell our condo, which he did incredibly quickly for a fabulous price. I would highly recommend Karl to meet and exceed all of your real estate needs.

We were in contact with numerous realtors and chose Karl due to his knowledge of the market and his straight forwardness. He was aggressive without being pushy and very responsive to any and all questions we had.We were so impressed with him as our selling agent we hired him as our buyers agent for building our new home . We would highly recommend Karl to any friend or family even with his crazy sense of humor ! Talk to him for 5 minutes and you will know what I mean !

Coming from big city life Massachusetts we were a little skeptical of everyone, and everything.... That said, after our second meeting with Karl we were convinced he was as real as he appears. Having worked in a professional setting for years, I was so impressed with his almost immediate replies to emails, to keeping on top of everyone, from the mortgage company, to the title people, to the inspectors, and including us in all correspondence. He went so far as to set up a cordial visit with the home owners and that is truly what sealed the deal on our beautiful home in Rindge. Oh, and Karl did not represent us., we were the buyer... it doesn't get any better than that. That's who he is. ***** five stars without question.

My family chose Karl after interviewing several agents. Karl took an unusual property and gave it the attention needed to come up an accurate price. He assisted my family, and my 95 year old mother, with compassion and care in the sale of her home. A home she has lived in for 65 years. Karl's Comparative Market Analysis of the property netted my mother with approx $75,000 more than some of the other realtors CMAs would have. When significant septic issues arose, Karl helped negotiate a fair solution for everyone. The sale went through with no drama and very happy buyers and sellers. His humor and attention were appreciated by all.

If you are looking for a realtor who is proactive and actually does what a realtor should do, look no further. Karl was the only realtor we worked with who actually called us when a new listing he thought we'd be interested came on the market. Not one other realtor we met over the past 12 months ever called us with new properties, rather they relied on us to do the searches and call them. Karl listened to what we were looking for, did his homework and would call us when new listings came on the market. As a result, we just closed on a property - start to finish it took an amazing 5 weeks. Within 2 days of the property hitting the market, there were several offers in already. Karl was able to negotiate on our behalf and although we weren't the highest bidder, the buyers accepted our offer. Also, the property we were purchasing was vacant so Karl would periodically go in and check on it, making sure the heat was on, etc. Any phones calls made to him were returned within minutes. If you are looking for a realtor who hustles and goes above and beyond to make the deal happen, look no further.

Karl Zahn embodies all of the qualities we hoped to find in a Real Estate Agent. Karl was very patient with us. We were looking for a very specific type of house and he never rushed us or got annoyed with us. He really seemed to listen and take into consideration our needs. Karl is extremely helpful and knowledgable about the area we moved to. Karl is always responsive with our questions. He always gets back to us in a timely manner. He had a good sense of what we were looking for. I really felt that he was not just trying to get us to buy any house - he truly knew what we wanted and helped us get it. His negotiation skills were on point and he was great throughout the entire process of buying and closing. We have now found our dream home thanks to the expertise of Karl ! The humor and personality he brings to the table is a bonus during what could be a stressful time of buying and selling a home. I would suggest him to anyone ! He is a one of a kind gem in the real estate world!
