The homes in the transactions I have dealt with have been in more varying areas that are nicer including Granite Hills, Eucalyptus Hills, and some other spots. In each case there was not a formal HOA or agreement. I find that the income level of the neighbors is more important then a formal association of some type with regards to the quality of the private road including maintanence. What you are saying does not ring true, yet again, my experiences have been positive but perhaps only because I have been lucky so far.
