Similarly, if you buy a house from someone who is retired, his or her taxes may be lower than normal (many states don't charge senior citizens school taxes after a certain age). You may think your taxes are lower when in fact they are higher. This can result in the lender not collecting enough money for escrow (the money used to pay the taxes at the end of each cycle). This will in turn cause your mortgage payment to go up if you allow the lender to pay your taxes and insurance.
Home owner's insurance can vary depending on your history with houses. If you've had claims in the past with insurance companies for repairs, your insurance quote may be higher. Credit can also affect your payment.
