I just ran active and sold listings in Beverly Hills on homes between 2000-3000 square feet and the taxes on the average price of active listings would be $23,876.18, and on the sold average price would be $29,143.75. I am going to attempt to paste the chart in here. This is based on taxes at 1.25% of the purchase price.
It's not letting me paste it so that you can see it, if you want to email me, I can send it as a word document...
You would have to contact an insurance agent to get a quote for insurance.
Are you planning to buy in BH or are you just curious?
