Well, if your intent is that you would live in this home as well, it changes things....but not by a ton. Unless you are able to save up $750k or more to put down on the house, it's probably not going to be affordable. B/c you're not only looking at your finances at this moment, but for the next 30 years. You don't have a car payment now. But you won't need one ever? Gotta have wiggle room to afford to buy a car. And pay for car insurance. And gas. Food and household bills will go up if you're covering the entire home. You will have to pay for maintenance and upkeep on the house. Assume 1% of the purchase price annually for repairs/upkeep. So you may have to cover up to $15k annually for home issues. You will have utilities to pay. On the home you could easily be over $500/month for gas/electric/Internet/water/sewer. More, if you live in an area that can get very hot or cold.
