New build properties

The maximum we will currently consider lending on initial occupancy/new build properties for Buy-to-Let mortgages is as follows:

  • New Build Houses and Bungalows 80% (subject to credit score)
  • New Build Flats and Maisonettes 75%

An initial occupancy/new build property is classed as any property being occupied and/or sold for the first time on the open market in its current state and includes converted and refurbished properties. These will fall into one of the following categories:

  • Newly built property.
  • Refurbished property i.e. refurbishment of an existing residential property. Typically a refurbished property will be considered as initial occupancy where the vendor is a builder/developer and the property has been vacated to allow for the refurbishment to be undertaken.
  • Newly converted property i.e. conversion of an existing non residential property, e.g. an existing mill converted into flats.
  • A property, either new or converted (as above), that has been tenanted and is now offered for sale by the builder/developer.

Property must be subject to one of the following building control and monitoring requirements:

  • Building Standards Indemnity Scheme from a warranty provider accepted by TSB.
  • Professional consultant - consultant must meet qualifying criteria.

New build mortgage offer

  • New build mortgage offers are valid for 180 days and are eligible for an extension of up to 28 days if the property doesn’t complete in time.
  • Applications are eligible for a further 180-day extension subject to successful re-valuation, credit search and affordability checks.
  • To request an extension, please contact your regional case management team (option 2).  The latest we can process the mortgage offer extension is
