Amen to everything Steve says.
Yes.
DJ0IP, who has done more practical research on off-center-fed dipoles than
probably anyone on the planet, has concluded they are fine up to 500-700 watts,
but problematic above that and not recommended.
Those conclusions are VERY strongly dependent on where the antenna is
installed with respect to victim equipment, and what victim equipment is
in the home.
In addition, almost anything fed by open wire line, especially OCF
dipoles, are magnets for RX noise.

Certainly as you increase power you are more likely to cause undesirable
effects in the home. Now I am going to make a generalization that I have
found true. The antenna type makes a significant difference in
interference. Unbalanced antennas introduce more RF into the home as
opposed to balanced antennas. An end-fed or off-center fed causes far more
problems than a dipole or inverted Vee. I have proven this to myself over
and over.
