As an owner - you would be responsible for real estate taxes.
You are not required to have an insurance - but if you taking a mortgage - the lender may require to purchase one.
lenders usually set an escrow account which is funded with monthly mortgage payments and which is used to pay your insurance premiums and real estate tax.
Without insurance - in case the legal liability arises - you personally would be responsible for damages.
