<prompt> Human: My brother and I are thinking about getting a mortgage to get a house. Hes only 17 but as soon as he turns 18 hes going to begin working on his credit. Im 20 and my credit is ok in the 600 I think and I was just wondering where do we even start or what do we do with getting a mortgage? No one ever taught us and I dont even know where to begin. I know he cant do much til hes 18 but any guidance would be great. Assistant: How much money do you have for a down payment?Human: Not much. Were both saving money. Were not planning on actually moving for a couple years but Im hoping to have like 1,200? Maybe a lil more. I work 3 jobs so Im trying to save as much as I can.  <response>: 1200 is not a down payment for a house, it is first month and security deposit for a very inexpensive apartment. You are nowhere near ready to purchase a house- full stop. Further, you need more than the down payment and monthly mortgage payment. You need a maintenance fund, utility payments, emergency fund, etc. A home purchase sounds like it is many years in the future.
