Before you do anything, figure out how much you are talking about here.
If you close in November, you will lose out on deducting whatever interest you paid at closing for the month of November, but December’s interest is not due until January 2011.
Most closing costs are not deductible, only points and pro-rata property tax (the property tax you pay at closing is on the portion that the seller already paid, not your rate).
Once you figure out the amount of deductions your benefit from deducting them is maybe 35% of that figure.
My guess is that you are considering jumping through a bunch of hoops to save less than $3000.
Sure, you can save a few grand by postponing until January, but your wife will have to spend another Christmas in the rental.
On the other hand if you put off closing forever, you will save a lot more 🙂
