"Selling is so much fun and exciting!"

Said no homeowner ever. Let's get real. Selling a home and moving can be stressful as well as a burden on you and your family. From prepping your home for sale to the constant cleaning for showings, you are going to need a kick-butt, no BS, MARKETING MACHINE of a Realtor(R) that can get your home sold quickly, painlessly, and for the highest price possible.

You are going to need someone with the skill set and knowledge to bring as many set of eyes to your home that would be humanly possible. Using technology and advertising to grab the attention of buyers is easier said than done. Unfortunately agents have gotten comfortable using the o-mighty MLS and generic "FOR SALE" signs to list one's home just to run off with at least 3-7% of your home's equity. An agents job in this market should be more about "how can this agent sell my home for more and take the headache away?"
