What happens after purchase agreement?

My builder did a great job from beginning to end. I am recommending friends all the time. Robertson Brothers staff have all been very responsive and understanding of my needs and concerns both prior, during and post purchase. The home is exactly as I had hoped. The design team was extremely helpful, and very knowledgeable about selections and truly helped me understand my options. Sales staff and construction supervisor was excellent...always answered my emails on time and treated me with respect. Finally, the closing staff was simply extraordinary. I don't know what I would have done without their help and tenacity to get my loan closed. I'm very grateful to them, Thank you Robertson Brothers you truly are the best!
