Hi Frank, most often the property taxes are prorated at the time of closing. The water bill is usually paid by the seller up to the date of property transfer. Having said this, everything is negotiable. It is imperative that you read the banks addendum upon their acceptance of any offer you make. You may find costs that they expect you to be responsible for. You may also have to pay a fee to the local water department to have the water turned on if it is off.
If you are in need of an agent to help you find a property and protect your interests, I would like to apply for the job.
You may contact me through my Trulia profile.
Good luck and Happy Thanksgiving to you.
