Buying a house question

So I’m buying a house sometime in the near future. I got approved for a loan through my bank. Now I have absolutely no furniture other than what’s in my tiny apartment but that came from my old college house. I have some in savings to buy new furniture and whatever else I need but would like to keep that there for emergency. So my question is, if I find a house below what I was approved for from the bank can I borrow a little more to buy this stuff? I was approved for $180,000 and obviously I won’t buy a house for $180K, thinking $150K and asking for a few thousand for furnishing the house.

Is this a thing?
