Interesting in house that is .30 of mile from high tension power lines
It might help keep stuff in perspective.
High power lines are an asthetic problem and not a health problem.

I can give you a better feel for this than "nothing has been
proven" or it is "guaranteed to fry you over time."
--------------------------------------------------------
Here is a comparison between the electric field of a 120V
household line ( running through your wall or to your
toaster ) and the 132 kV line on the tower:
What you get in the house at 6 feet is the same that you
get from the 480 V transmission line at 12 feet which is
the same field you get from the 132 kV line at 199 ft.
Flipping it around, the field you get from the 132 kv line at 1,584 ft
( the distance to the house you are considering ) is the same as
the field you get from the household line at a distance of 159 ft
and the 480 V line at 318 ft.
I'd say that if you are comfortable being within about 160 feet
of a household toster ( while it is toasting ), then the power
lines should not stop you from buying the house.
--------------------------------------------------------
What follows is some technical stuff that no one probably
cares about , but it added for reference:
0.3 miles is the same as 1,584 ft. and 483 m.
If the power line is a large cross-country transmission
line, the voltage is probably 275 kV or higher.
More likely, it is a local Smaller steel pylon line (132 kV).
The wooden power lines might carry ( about ) 10-30 kV.
The electric field is expressed as ( volts per meter ) or V/m.
Note that if you are being exposed to an electric field, you
are also being exposed to a magnetic field ( Tesla's ).
Note that I didn't give you an exact figure for the electric
field because that magnitude fluctuates over time depending
on other electromagnetic interference from stuff like solar
flares and fluctuations in the resistance of the air like
humidity, volcanos, stuff like that.
Note that if you cannot actually see the lines due to other
houses/trees in the way, some of the electromagnetic field is
getting absorbed by those things. Other lines such as phone
and power lines will tend to shunt some of that field also.
All of the above is worst-case, of course. In a three-wire
transmisson line, there is also a canceling effect, but
I don't want to figure that out. My math is too rusty.
