Assessed value taxes and city violation in Detroit, Warren, Roseville and more

[Chanie Chriqui]

Just wondering what people do when they come across these 2 issues that I have been having with my properties: 

1) The real estate taxes jumping really high after the new assessed value comes out? We filled to have them lowered, but no luck. They are 6-8% of the assessed value, is that normal? I thought its usually around 2% 

2) How do you get around the city violation? Every year in Detroit and nabourghing cities you need to get a rental certificate, and every year they threw at us a large list that cost so much to fix. Since we have a property manager, all these things cost more and we are not even doing things that raise the value of the property. 

All suggestions would be appreciated
