Never budget based solely on your loan officer's initial Closing Disclosure quote if the seller held the property for multiple years. You can request your lender to escrow based on the purchase price from Day 1, or proactively set aside the projected tax deficit in a high-yield savings account (HYSA) to pay the lump-sum shortage when the Year 2 escrow analysis arrives.
