Just make sure you can schedule your walk thru and closing time with them so that you have the necessary time to fly in and drive up to TV.
We closed last week by mail and it was very easy! We received the closing packet via UPS on Friday - it contained very explicit instructions - had the documents notarized as indicated and sent them back via UPS. We received a call once they were received congratulating us as new homeowners! The only downside of the experience was that we were not able to be there for the closing, but it all worked out in the long run. Best of luck with whatever route you take.
