You get rid of (what sound like inherited) tenants that are a hassle - and will continue to be - their behavior never improves, fyi. 

I got rid of about $2,500 worth of trash out cost but then some one can in that night and took all the appliances ...lol Wont do that again or get an alarm.

Just hire an experienced eviction attorney to get rid of them as efficiently as possible.

Have they moved this page or gotten rid of it completely?

But to reverse your question, simply ask... with so many changes in the industry and so many bright people ...why haven't we got rid of agents? 

Get rid of the kitchen before any discussions with the city...otherwise you risk revealing to them yourself that it was an inlaw unit!

-However if they seem like they are going to cause trouble, how hard will it be to get rid of them?

It seems like it should not be legal, in effect taking something without any LL compensation (freedom to use unit for whatever LL desires at the end of lease).Besides my primary issue that the law changes an existing contract, it also makes it harder to get rid of less than ideal tenants that raises risks and costs.  

Repairs should be 10%You can get rid of Capex though, as no one really worries abot it on SFR.How much research have you done on property taxes?

If they make a fuss, get rid of them.
