The maximum loan amount I can approve for you prior to selling your existing home is 453,000
I took this to mean I was approved for a loan of this amount and didn't need to sell my existing home to qualify for it.
I'll go into more detail later, as this is currently unfolding (and collapsing), but just wanted to get your take on how you would interpret that. I know lots of people qualify/get a mortgage to buy a house or construction loan in addition to their current mortgage and then sell their current home later. I assumed that's what this meant.
