Your property is magnificent! I really do not think you can improve on the pictures and everything seems to be laid out perfectly.
The only area that you might check on is your rates. Are they competitive with comparable listings near you? This is important.
Also, you might want put that 2B1 Marstons Mill Airport is near you. I fly myself everywhere and there are many like me that like to fly into a location instead of going near large airports.
Hope this helps.
