I worked with David and Tiffany for purchasing my first home recently. Firstly, it's important to note that in Las Vegas everyone and their brother is a real estate agent. The few I met before were really pushy and seemed to be interested in mainly their commissions. But there is a good reason why David and Tiffany have been around for many years -- they are veterans of the industry and know how to get things done.
Mainly, here were my core reasons why I liked the service and experience:
(1) They were not pushy and worked with my budget/goals without pressure.
(2) The communication was solid. They cared about not wasting my time.
(3) They recommended solid vendors who delivered on everything from the mortgage broker to the home inspection people.
(4) They were sensitive to my lack of knowledge and educated me in the process.
But here's the real kicker. AFTER I purchased my home, their support was still there.
For example, when my garbage disposal and garage doors broke, they sent someone over to fix the problems free of charge. They cared about my needs and problems even after the transaction was complete.
You don't find that every day. For those reasons I would highly recommend working with them for buying a home.
