Two Ways To List

Flat-Fee Or Traditional

Karten Real Estate Services is a full brokerage and agency serving New York City and Long Island. Sellers choose the structure that fits the home and the timeline. The service level does not change.

Option One

Flat-Fee MLS Listing

A set listing rate instead of a percentage. Your home goes on the MLS and syndicates to the major portals, and Mark still handles the pricing, the calls and the negotiation personally.

  • Full MLS exposure and portal syndication
  • One set rate, agreed up front
  • Mark handles offers and negotiation
  • Best for confident, well-positioned sellers

Option Two

Traditional Full-Service Listing

The conventional commission structure with the full marketing program behind it: preparation, presentation, pricing strategy and negotiation, start to finish.

  • Complete preparation and staging guidance
  • Professional presentation and marketing
  • Pricing strategy from a PSA-designated broker
  • Best for complex, estate or higher-value sales

Sellers and buyers across New York City and Long Island.

★★★★★
Mark Karten did an excellent job in selling my home in Flushing. He followed through on every promise he made regarding his listing and marketing process, especially his use of his signage, technology, and ability to access the house virtually 24/7. As a result, we had many showings as well as offers. Mark was a great communicator, updating me consistently regarding changes in the neighborhood regarding competing listings and closings and how they would affect my property’s value. Mark is clearly experienced and professional from start to finish and I highly recommend him to anyone considering the sale of their home.

Mark was a delightful professional. My wife and I recently closed on the sale of our home of 25 years. Mark Karten provided the ideal mix of real estate knowledge, patience advising us as our listing agent, and wise advice throughout from preparation of our listing to pricing to fielding offers. We would recommend Mark Karten to any buyer or seller of New York residential property. You couldn't find a more effective and easy to work with pro.

Excellent level of service. Mark Karten provides an excellent level of service. He was available whenever needed to ensure we were doing things correctly, and to provide support. I would recommend him without reservation as Mark provided an outstanding experience.

★★★★★
A very helpful guide and advisor. Mark knows his stuff. He advised me in selling our home and it was a success. He is very communicative and responsive. Make sure to watch his intro video that answers almost all of your questions you might have. For sellers who are willing to put in a bit more work, Mark is the perfect partner to providing wise and timely guidance. Some higher level advice is properly priced as they are worth it. I highly recommended Mark to anyone who is using Houzeo to sell their own home.

Wonderful experience! I was paired with Mark through Houzeo. I honestly couldn’t have chosen a better agent myself. He was very responsive! And, he put our mind at ease through the complicated sale of my parents house. He was available to answer all of my questions. I would highly recommend Mark for all of your real estate needs! Thanks, Mark!
