Overview

A mortgage plan that respects new-build deadlines

New-build purchases can move quickly at the start and slowly near completion. Developers may set reservation and exchange deadlines, while the property itself may not be ready for months. AJM can help you prepare early, understand which lenders are comfortable with new-build homes, and keep an eye on mortgage offer expiry dates if the build timetable changes.

  • Income documents, bank statements and deposit evidence.

Practical guidance

Common questions about new build mortgages

Why can new-build mortgages feel time-sensitive?

Developers often expect buyers to progress quickly after reservation, so it helps to have income and deposit documents ready before you commit.

What happens if the build is delayed?

A delay can affect the mortgage offer expiry date. AJM can help monitor the timing and explain the options if an extension is needed.
