Gentlemen,, My family has been buying CA tax sale foreclosures since the 1960's...
The Sale is final... The only way the sale can be overturned if a the owner that lost the property can prove through a court action that the county messed up the sale. IE missed the publication times, and notification requirements.
When we were hot and heavy in this bizz we would buy 200 plus properties a year and before you get excited we were buying properties for 200 dollars to 5k
Each title company had their own requirements for title insurance. Fatco wanted 5 years .. but we got Fidelty to insure the day we got the Tax sale deed and recorded it. the fact is there is no redemption period in CA.
however reality is if your only buying a few properties a year your not going to have any juice with a title co.. the one that insured ours ( we closed 500 plus transactions a year)..
worse case scenario is wait a year and sell it.
We did have one property that we bought were they challenged the sale and the county F up and the judge nullified the sale.. so one in 40 years
