Although you might be able to find issues with RFI ahead of time and by all
means I'd do it - I can say here at my location I didn't find anything that
was overly alarming from the ground. Other than one power line noise issue
and that kind of RFI you can generally get corrected. Even when I tested my
monobanders on the 'test tower' at 37' noise wasn't really evident - one in
one direction was there but just a slight rise ... it wasn't until the main
tower went up and the antennas at their full height that all of this stuff
showed up - noise from most every direction and I'm out in the 'boonies' a
bit on 11 acres ... its quite depressing.
I now am working on a portable SDR radio and I'm going to wear a
construction vest to hopefully look benign when I walk up to someone's house
with this equipment. Besides more power line issues, now up to 4 different
directions out to over 3000' away (one fixed, one to be fixed - the worst
one the Power company says is not their fault as it is underground and their
HV line ends before where I get the noise) ... a GROW light from 700' away
and at least 2 plasma TV's in different directions...
I miss my very nice rural location in Arizona.

The all of the junk being manufactured it is becoming harder and harder to
avoid RF noise.

Also great advice.
And do an RFI survey -- look for local sources of RF noise. How close are
neighbors? Most modern homes have several dozen noise sources in the form of
battery chargers, digital electronics, and switch mode power supplies built
into equipment. Any solar systems nearby? Some are quite noisy, others are
not.
What's the terrain like? Try running HFTA on it.
