We live in Ladera Ranch, with no views of power lines. I have to agree, that you do see them driving into town and if that bothers you, than I would not think about moving here. I don't see that many for sales signs as I did months ago, however I think the worst is yet to come. Many people bought way beyond their means around here and are only making those minimum payments on their option-arms. I would rent for a while and safe some money that would be lost in the next two years as the market drops some more.
We bought in 2003 at a fixed rate and are here to stay. Our taxes are about $14,000 a year (including mello roos) and our HOA is $200.00 which includes internet. We live in a 3600 square foot house. The townhouses have higher HOA fees for sure, some as high as $450.00 a month. I would recommend renting here for a while and see how you like it. We love it! From the Flintridge Village we can walk to the school, shopping, clubhouse, dogpark, etc . . . and we know every single one of our neighbors and look out for each other. Our old place in Mission Viejo, we met hardly anyone in the 6 years we lived there. We also have block parties every few months and our kids play together. That being said, I would check our your prospective neighborhood and see who your neighbors are first. That was a huge thing for us. Avendale is a little dense for us, but Oak Knoll has some nicer older townhomes within walking distance to shopping, etc . . . There are some nice townhomes in Echo Ridge Village which have a view as well and are close to everything.
Hope this helps.
