It's really $290 in fees plus PITI. If you want to treat the mello-roos/CFD as a fee then it's $600 plus PITI.
BTW, what's an AD Tax? Oh, Assessment District.
What do they get for that? Yea yea, I get it, new roads, sewers, etc. But I mean, what do they get for community amenities?
Northpark II has multiple big pools, clubhouses, pocket parks (that's all HOA for maintenance), the schools, streets etc, for the mello-roos.
What does Cambria have? I all I see in the plans are streets filled with houses.
