<prompt> Human: My wife and I are in the early process of planning to purchasebuild a new house, but we are unsure how much monthly payment can we make towards mortgagetaxes. Here is our financial situation:Income:My wife currently makes 265,000 annually, and I make 97,000. I also run a small online business that probably will net 20k - 30k in profits this year. Other assets:We have about 25k in liquid cash in our bank. About 65k in stocks that have quite a bit of capital gains to them. Maybe around 50k in retirement asset that we dont really want to touch. Debt:We are paying off my wifes student loans aggressively at around 2,600 per month. The student loan is on schedule to be paid off completely in about 3.5 years. We also have about 100k left in our mortgage, and the house can probably be sold in the 180k range. We are currently paying 2k for mortgage and taxes, which of course will be replaced with the new mortgage payment.Expenses:We dont really spend that much beyond the typical standard living expenses, although we do like to take a vacation each year. The main expense we have is child-care. We have just one kid now, and we are currently paying 30k for child care. He will go to pre-school in September of next year, and this cost will drop down to 20k. But if we have a second kid which we are planning to do, we are expecting combined childcare cost for two kids to be in the neighborhood of 50k.  <response>: Well, on your income you can realistically afford a house in the 500k-1.2m range. But, you really do not have very many retirement savings for how much money youre bringing in a year. With an 80k profit off your home sale you still will want to build a bit more of a downpayment, but Im guessing youre looking to get into a second home and out of your starter home?
