Vs the contra to that, they get mad and say "now you can evict me".

Due to my profession as an aircraft mechanic, I consider myself "handy" and able to quickly learn how to utilize various tools and techniques for repairs and maintenance. 

If so, based on the relatively new laws about bed bugs here, and the fact that you can’t identify specifically which unit introduced them, and - lastly - that our state considers any unit infested with bedbugs to be uninhabitable, I’d say you’ll have to eat the cost on this.Here’s some links with some more info on the topic:SF Gate: A Landlord's Responsibilities for Bug Infestations in CaliforniaAAOA: New Bed Bug Laws Apply to California LandlordsBed Bugs and the Law in California - Contra Costa Health Services

I have Section 8 tenants in Alameda County and Contra Costa County....right across the bridge from San Francisco and when I hear people panicking about rent control and/or not getting rent from their tenants I sleep easy because I know my rental income is guaranteed by the government, and I don't have to worry about my tenants going on a "rent strike".  

Use a local RE attorney familiar with the Ins and outs of land contra acts in your area. 

I'm also an automotive and aircraft mechanic, so I'm used to things not going right and lots of surprises. 

I bought the first house in CA ( Contra Costa) - 350k.I'm working as a full-time employee, software engineer, making around 126k per year.How much I can deduct:1)interest (1st year is about 9.5k interest payments). 2)property taxes (I heard maximum deduction for prop taxes - 10’000)3)home insuranceCan I deduct them all?  

On the other hand, aircraft manufacturers posted a whopping 462% decline in bookings.

My apartment was in Contra Costa County CA.

Now a lot of properties have fewer days on market and are getting snapped up by eager buyers that are outbidding each other and at least in Alameda and Contra Costa County it is a very strong sellers market right now.
