I bought my first house with Nick in 2011. Being the first time home buyer, initially I was very nervous about the process. Nick made it a very smooth and enjoyable experience.
He was very professional, courteous, helpful and above all very honest. Never made me feel rushed. Always gave his honest opinion about how much I should expect to pay for a specific house.
I was in the market for almost a year. During this whole year, Nick showed me a lot of houses. When ever I asked him to put an offer on a house, he was very prompt. I lost on few houses only because I was not willing to pay the price Nick thought was reasonable (and later those houses were sold at the prices very close to what Nick had estimated) .
When ever I asked him to show a house, he was very quick in arranging the tour. Once I called him during lunch break, asking him if he had time to show me a house. He was at the property in 30 minutes. We put in our offer the next day (it was a foreclosure). Bank came back saying it had multiple offers and asked all the bidders to come back with their best offer. I followed Nick's advice on how much down payment I should put and how much total price should be. We won this time.
I would definitely buy/sell with him again. If you are selling/buying, I recommend him whole heartedly without any reservations.
