This is from the DOE website https://www.energy.gov/savings/residential-renewab...: "A taxpayer may claim a credit of 30% of qualified expenditures for a system that serves a dwelling unit located in the United States that is owned and used as a residence by the taxpayer."

Another way is to try the county's tax assessor website or go to the local superior court.

Here is what @Nicholas Scatton was referring to:https://www.biggerpockets.com/forums/742/topics/54...

On the CRT website, one type of dispute they will look at is "issues of financial responsibility for repairs and the choice of bids for services."

A lot of wholesalers will do this already and refer you to a contractor that they have at no additional charge.I am not sure the exact business model you are thinking of here.

If you can’t find one, go to the California Association of Realtors website and they should be able to direct you.

I highly recommend finding a local meet up through the events tab of the website.

Oftentimes, the "free to use" websites are 1-3 days behind, and by then, the properties are off the market. 

BP is one of the best online real estate investment websites.

Thanks for the advice and I look forward to connecting with even more people on this forum/website :)
