<prompt> Human: Lots of details here, but I want to make sure everyone has the full picture before weighing in. Im looking for an answer if this is a smart financial decision for me and my family. Family BackgroundIncome: - I currently make 95K per year in a very stable position. Expected not definite to increase 10-20 in the next few years.- My wife is not currently working and stays home with our new baby. - After 401k 5 which maxes company match and company stock plan contributions 10, my after tax take home pay is 4400 per month. - Current mortgage is 1450 per month. - Other mandatory monthly expenses car paymentinsurance, student loans, cell phones, utilities, gas, groceries, household supplies are about 2000. - The rest of the monthly budget 900 is usually spent on non-essentials, such as shopping, restaurants, bars, home improvements, etc. - Generally we have little to nothing left over each month, with our primary savings being from the stock plan contribution. I contribute roughly 800 per month at a 15 discount and I can sell after holding for 1 year. Company is extremely largestable. - We currently have about 80K available for a down payment on a new house after selling our current home, selling company stock, and combining with cash savings leaving 15k in emergency fund. House in consideration: - Listed at 529K. Estimating we could purchase for 500k. - Taxes are 14K per year. 1,165 per month. - Down payment of 100k and estimated closing costs at 16K. 116K to close. - 400k financed at 4.125 would be 1,939 PI per month. - Homeowner insurance estimated at 2,400 per year, 200 per month. - House is 4100 sqft current home 1500 with 10 acres current about .25. Built in 1790. Estimated utilities and maintenance of an extra 200 per month over current bills in northeast, so high winter heating bills. - Overall estimate of 3300 mortgage plus 200 extra in maintenanceutilities. Roughly 2000 over current payments. The twist: - Obviously this seems way out of our budget. 2000 over our monthly budget, and were short 36k cash needed for the down paymentclosing. - The twist is that this is my wifes parents have offered to help us buy this house, as it is the house my wife grew up in. - They have offered us 100k to help us buy this house. This would cover the 36K shortage to close and leave us 64K leftover. - The 64k could either go towards the mortgage 336K mortgage or be used to cover the 2k shortage each month. Best case this buys us 3 years. After our savings run out, our options are: - My wife goes back to work. - Im making significantly more money. - We ask our in-laws for more help. - We sell the house gaining very little equity. Does anyone see anyway this makes financial sense? We think the offer of 100k would only really apply to this house as it has sentimental value. So if we decide against it we may be, giving that up. TL;DR Considering buying a house with a mortgage 2,000month over what we can afford. In-laws have agreed to give us 100k to help us make it work. Dont see how we make it past 3 years.  <response>: The taxes alone are 25 of your take home pay. The is a textbook case of a bad idea for housing. If you do this, you will be stressed financially for a long, long time to come, which will likely have a negative impact on your relationship with your wife, your kid, and your in-laws.Dont do it. Youre already tight with your budget, this would make it far worse. I would strongly recommend just staying where you are, cutting your existing expenses a bit to save some more, and look into buying a new place in 3-5 years after your income goes up, your wife goes back to work possibly, and you have a nice cushion set aside.
