Find Your Next Home
You need someone who knows this area inside and out! I can work with you to find the right home at the right price for you, including all the neighborhood amenities that matter - not to mention the essential criteria you have for your ideal home

Sell a Home
When it's time to move, you need someone who will advertise your home, show to prospective buyers, negotiate the purchase contract, arrange financing, oversee the inspections, handle all necessary paperwork and supervise the closing. I can take care of everything you need, from start to close.

Consult on Home Selling Tactics
Oftentimes buyers don't visualize living in your home the way you do. I can make your home attractive to its ideal audience - which can help you get top dollar. Things like staging the home, making repairs or minor improvements, or even simply painting the walls can be the difference between a home resting on the market and one that's sold fast.



"Wonderful advice and prompt service for first time home buyers! Very professional and thourough. Would highly recommend. "

  -Carolyn Smith, Client

"We had our house for sale over 3 years. With several different  real estate companies. Listed with Dave & had it sold in less than 6 months. (fast for north county at that time)He is a man of his word if he says he is going to do something he does it! Not like all the other realtors that we had they would just tell you what you want to hear and do as little as possible after you sign with them. He is an A+ in my book!"
