Yes, but because of the high value of the property, your deductions can be huge. I was using the word "credit" a bit loosely. The point is that her deductions is well above the quoted $180K. The equivalent extra refund she'll get due to them was $180K.
This is also because they are high income earners (one of them has a regular job), and they've manipulated things so that they can apply the deduction to the W-2 income (not usually possible). The federal tax bracket is 35+% - not sure if they can apply it to their state's income tax, but if they can, it's another 10-11%. So you don't need a massive deduction to get the equivalent of $180K refund.
