These numbers are approximations — meant to give you a general idea of your costs, not a final figure. Confirm every closing cost with your real estate lawyer and mortgage professional before you rely on it.
Penalties must be confirmed by your lender — variable is usually 3 months' interest, fixed is usually the IRD, which can be much larger.
Not included: capital gains tax if this isn't your principal residence, staging, repairs, or any bridge financing.
