Mortgage offer
A mortgage offer is the lender’s formal offer to lend a stated amount on a stated property. An agreement in principle is earlier and weaker: it is an indication, not an offer.
Also called Formal mortgage offer.
Do not mix the two up
Buyers often say they are “mortgage approved” when they have an agreement in principle from before they found this house. Ask which document they have, and whether it names this property. A down-valuation can reduce what the lender will advance even after an earlier indication.
US wording
US agents say pre-approval or pre-qualification, and then a loan commitment. Pre-qualification is the weaker of the two. Use the buyer’s actual document, not a translation you are unsure of.
