Investor-Rental property insurance

Hi all, under contract on my first ever investment property! Its a duplex and is a great deal. Before we get this party started, question foryou pros on insurance. Did some research and sounds like I can’t become an LLC because banks won’t loan to you since they can’t come after your personal assets. Makes sense to me. What type of insurance do you guys get on your investment properties (coverage types, amounts, etc)? Anything specific to look out for? Got a few quotes and thinking $1M in liability is where I want to be, what do you think? Quotes look to be about $70/month on the duplex. Cheers Rich
