Help- need advice on TX foreclosure

I have a 2nd on a home in Austin and also 2nd on a re-hab in Texas with the same guy.
I live in CA.

I had trusted him and now I am very worried.

The notes came due and he has refused to contact me. I already sent the demand letter for 20 days and now his time is up.

What do I do now? Any advice? The total is about 117k.

What will it cost me to handle the whole thing?
