Life and Work?! (Portland)

Hello !

My Name is Tim and I am from Austria! I love Portland and i will come to Portland to live and work there! I will take my family with me ! I have two kids Protected content ) and Protected content ) and a lovely wife !
I am Network Engineer right here in Austria!
I have a few questions and it will be very nice to get answers.

I tried to calculate how much tax i have to pay if i would earn Protected content a year, but it went wrong because i have no idea of the tax system!

I want to rent a house for 2 years and maybe we will stay longer in Portland we will buy one! Are there any good estates or companys where i can ask for my issues?

How about the health and dental care or insurance for my family?

I knew that this are tricky questions but maybe one of you can calculate my taxes so i have a good view about how much i have left for other things!

My salary is about Protected content a year.

Thx in advance!

Tim
