Hi! We are buying something and found out the Mello Roos in the Disclosure Source document Pacita mentioned. (Though we didn't get the document until after the purchase agreement was signed.)

We just had our place inspected by James Byrd of A Plus Home Inspections. http://www.aplushomeinspectionsonline.com/
He had great credentials and gave me two buyer references when I asked. He was courteous and personable and thorough. Plus he gave us a lower price than expected.

Another guy recommended by two agents here is Marc Harmon http://www.theinspector-home.com/
I called him initially and he was extremely busy. His quoted price was higher than on his web site and when I emailed him he said they were changed a month ago (no apology, just very curt). When I asked for references he ignored my request. Could be he was too busy and didn't need the job (he's also a contractor.) Take it for what you will.
Hope that helps--and best of success with your search!

Most listing agents would include a disclosure package from companies like Disclosure Source or Property I.D. that should have information on whether or not the property in question is subject to Mello Roos.

If you're representing yourself, or if the property is for sale by owner, this is the kind of information you should insist upon.

As for inspectors, there are quite a few. You can choose companies like LandAmerica that can do pest inspection, roof inspection, property inspection, etc. http://www.inspectech.com/. You can also visit the website for American Society of Home Inspectors to find ASHI certified inspectors in your area http://www.ashi.org/

If you are represented by a realtor, these are questions he/she can answer for you. Most of us would have a list of resources for such services.

Take care and good luck!
