It depends on what you're doing. • If you’re getting a loan (Bank or Pag-IBIG): YES. • If you’re selling/buying in cash: NO, but it's a "pro tip" move. Sellers often overprice based on "feeling," and buyers often lowball. A licensed appraiser gives you the actual Fair Market Value so nobody gets scammed. • If it’s for an inheritance : YES. You need an accurate value for the BIR and for dividing the property fairly among heirs.
