Anyone can put something up for sale. But with the complexity and legal ramifications involved in real estate transactions today, few have the training, skills, expertise, and experience needed to 

(a) market effectively, 

(b) tap into large buyer pools, 

(c) motivate/excite buyers, 

(d) negotiate and close, 

(e) protect the interests of their client, 

(f) manage the overall transaction process, from listing to closing, 

(g) foresee, recognize and avoid risks, errors & pitfalls, 

(h) assure that all current legal & contractual requirements & considerations are addressed, and 

(i) yield the best possible result (contractually and financially) for the seller and/or buyer. 

Much of what Realtors do is "invisible", representing many hours of work behind the scenes. This includes preparing listing presentations & documentation, MLS data entry & updates, preparing, submitting and monitoring (and paying for) all forms of advertising/promotion, managing access to properties (keys, keyboxes, security), coordinating all showings & appointments, working with prospective buyers (directly or through other agents/brokerages), coordinating all negotiation & documentation aspects of the offer/counter-offer/contract process, coordinating all action items associated with the escrow/title process, and assuring that their client's interests are protected. 

My job is to take care of all of these items for you so that the only thing you have to worry about is getting packed up and moved. My goal is to make the process as stress-free as possible for my client.
