Taxes on Contract For Deed

Looking to do my first Owner Financing deal and had some questions while I try and figure out rates and terms. My payments now take into account my Homestead Exemption for my escrowed taxes. On a contract for deed, will the buyer be able to get Homestead on the property or will the taxes go up to the non-exempted rate? Also, what type of insurance would I be required to carry on the property? Would it be less or more than what I pay as owner/occupant? Any other differences in my monthly payments that I need to take into account? How is it handled if the tax rate/appraisal changes the payments mid-loan? Is that increase passed along to the buyer?
