If the soffits are not metal, they will probably be dry and just about
anything will do for an insulator/standoff.

When you said "eaves", some of us assumed you meant under the lowest
edge of the roof. Technically, eaves are the under part of a roof that
hangs over a wall. So the overhangs at the ends of a gable roof are also
called eaves. An inverted vee at one of the ends, fed in the center,
would be something to consider seriously if you have a gable roof. The
center would be perhaps 18 feet above ground.

On the other hand, if you have a hip roof, then a wire under the eaves
will be entirely horizontal and approximately eight feet high. Such an
antenna will exhibit a near-vertical radiation pattern and it will not
be much of a performer for DX on the HF bands.

Good luck

I make no predictions but you will probably be pleased with results.
