buying first house, taxes question

[Tab B.]

hello im getting ready to buy my first house, and i have a few questions. one of them is property tax. the house im looking at says that the taxes are 10k, and the mortgage payment is about 400 a month. so that means my payment monthly will be (10k / 12 = 830) 830 + 400 = 1230 ??? if so do i get any of that money back when i do my taxes? if so how much? i dont need exact number, im just trying to figure out how much house i can afford and still live comfortably. thank you for any answers!
