Only attic. 2 1/2 year old house. Just seems very very hot in attic and not a lot of insulation when I was waking up there. Hotter than any house I've had
I did the blow-in insulation. It was very easy and ran about $400-500 for the machine rental and 8 bales of insulation I bought.
Unfortunately, due to the way my townhome is positioned and the fact it shares an attic with the neighbor...it didn't help a ton. I think in a house it would work better. Worth a shot if you don't want to spend the money on foam - stuff is very pricey.
ETA: If you go foam, you need to be careful with open cell vs. closed cell. IIRC, with the humidity and rain we get in south LA, you'd want open cell. Closed cell will trap moisture and cause mold/rot.

Did you air seal before you put that extra insulation in?
I air sealed my attic and added about 18" of blown-in cellulose. I'm in a condo as well. Whether you share attic space with your neighbor is pretty irrelevant if you air sealed to prevent YOUR cool air from escaping.
