It'd be interesting to know if you know the date of the satellite view of the property that you are looking at. When I look at my place, the satellite view is from Spring of 2005.
Do all the "free" satellite viewing sites use the same images??
Google earth, that site, and the
http://www.weather.com all use the same image of my place.
I 2nd the thought of checking into the noise of the airport. Even some prop planes can be pretty noisy, especially between 10:00 p.m. and 6:00 a.m.!
