What is a mortgage in principle?
A mortgage in principle, or decision in principle, is an early check by a lender. You give them details about your income, spending and deposit, and they carry out a credit check. If you pass, they tell you roughly how much they could lend.
Many estate agents ask for one before they will take an offer seriously, so it can help you show you are ready to buy.
Mortgage in principle vs full mortgage offer
A mortgage in principle is not a mortgage offer. The lender will still need to check your documents, value the property and complete their full underwriting before they make a formal offer. The amount could change or the lender could decline.
An adviser can help you choose a lender that fits your situation before you apply, as too many credit searches can affect your credit score.
When should I get one?
Usually before you start viewing homes seriously and well before you make an offer. If you are in Portsmouth, our first time buyer mortgage in Portsmouth page explains how we help.
