And, of course, even this is not foolproof.  When looking to buy the
house I'm in now, I went to a neighboring ham's home and listened to
all the frequencies of interest, heard nothing, and asked him if he
ever had noise problems...he said "no".  Then, I hooked up the mobile
rig and drove all around the subject property with not a bit of
noise...I thought everything was cool.

Well, turns out that I did my noise checks on a quiet night.  

BRRAAAAAAP!

You need to make these checks under varying conditions over a period
of time to be more certain of your analysis of the noise environment.
