Property taxes come with a lot of exemptions. The primary one in Florida is the Homestead Exemption. You would not be able to deduct the exemption from the value of the property if it is not your primary residence.
Income prodicung property can not be your primary residence.
You should contact the property appraiser in Hillsborough County and find out about the particulars directly from them.
Also you need to verify the Community Development District Taxes. Many communities in New Tampa have high "non advalorem" CDD taxes. You can pull up the address on: http://www.Hillstax.org and find the exact amount of the CDD (if any). Hunter's Green and Cross Creek and some older areas of Tampa Palms do not pay CDD taxes but the majority of the other communities in New Tampa do pay CDD taxes.
Your Realtor can help you gather this information.
All the best,
