What "standard multiple" did you use when buying a house?

I’m in the market now, I went to my bank got pre-approved. I’m looking at homes 50 k less then I was approved for. I’m looking to have less then a 2k monthly payment. I figured out how much I spend a month, added cost of living, and then kept a grand a month open and it still leaves me with money in the bank. So I can comfortably step into a very nice home and still afford my lifestyle. I don’t want buying a house to change my ways.
