I also strongly suspect that you are overestimating the magnitude of the tax increase you will see but if course it's very hard to know without the details of your particular financial situation. In particular I will note that the mortgage interest deduction is grandfathered in for current homeowners and the elimination only applies to loans over 500k (and that's only in the house bill. the deduction remains completely in the senate bill. it remains to be seen what happens in reconciliation).
