Horse/rider size

Hello,
   
I am looking into buying a horse, and have found one that I am quite interested in, but I am kind of reluctant because of my weight. I am 5'6"-5'8" and weigh around 230lb. The horse is a 5 year old Throughbred gelding who stands at 16.2hh. To see a picture of him and his build, follow the link: http://www.garrisonequine.com/16%201%20hd%205%20yr%20TB%20geld.jpg
   
I have been riding for approx. 5 years and have good balance and coordination.
   
Thank you!
