<prompt> Human: Ive never bought a house before but I am looking to. Theres a nice house for 130k in my area. The zillow estimated mortgage payment is 500m. You cant even find a rental in my area for less than 800 a month, and a comparable rental would cost 1100 a month. There must be some catch here right??  <response>: A lot of times its not the mortgage payment that gets you, but all the other stuff that goes with it.If something breaks, its not your landlords problem to fix. If there is an HOA fee then you pay it. I dont know if taxes and other stuff are included in zillows calculator but if they arent then stuff like that too. Then there is PMI if you dont have a large down payment.The loan is probably half of the total expense.
