The Mello Roos is taxed deductible. The HOA keeps the area nice and Eureka Springs has very nice community areas, its $150/month.
The price for these homes is significantly less than other similar sized homes and/or smaller, at least as I have noted over the past almost six years. These homes are a great buy. They are close to Daley Ranch, surrounded by beautiful hills. I like Escondido it's a fun place, with a small town appeal. Everything is within 30-45miles plus theaters, and a nice mall.
If you are looking for a nice place in Escondido I might consider Brookside, Emrald Heights, or something South in Escondido such as Candlelight hills, Lomas Serenas, etc. Great neighborhoods without the crazy cost of Eureka Springs.
