The affordability check

What is the affordability check?

New-build LTV caps and the way lenders treat builder incentives vary from lender to lender. The check runs your figures through every lender's real affordability rules and shows which ones will lend on a new-build, and how much.

  1. Tell us your figures

    Income, deposit and the property you have in mind — a few questions, about a minute.

  2. We check 58 real lenders

    Your numbers run through each panel lender's own affordability rules, using the details you give.

  3. See who'd lend, and how much

    A ranked view of which lenders would lend to you, and the amount each would offer.
