Property restrictions

Property concentration exposure limits

The Mortgage Works will consider its overall exposure by applicant, geographical area and development when assessing applications. The maximum number of securities that can be considered per development is:

  • 1-3 units: 1 unit
  • 4-50 units: 25%, rounded down to the nearest unit
  • 51-80 units: 12 units
  • More than 80 units: 15%, rounded down to the nearest unit

These exposure limits are per applicant and include securities mortgaged to other lenders.

Scheme abuse

TMW Customers aren’t allowed to live in the Buy to Let property at any time and will be in breach of the terms and conditions of the mortgage contract should they choose to do so. Where this is the case, TMW’s policy is to give the customer a period of time in which to vacate the property, or instead remortgage to a residential loan. If a customer fails to comply with these terms, this may lead to legal action being taken against them, which could ultimately result in TMW taking possession of the property.

Minimum property value/purchase price


New build buy to let applications

New build flats and houses are defined as:

  • A house/flat built within the last twelve months
  • A house/flat built over twelve months ago but still owned by the developer
  • A house/flat built over twelve months ago but the first purchase/legal completion of the property was less than twelve months ago
  • Applications for new build flats accepted up to a maximum of 65% LTV
  • TMW instructs its valuers to value all new properties (flats, houses and maisonettes) on an 'as new' basis
  • Builders must be on TMW’s approved list (see TMW website for more details)
  • If new, or built within 10 years, the security must have a warranty guarantee under NHBC, Premier, LABC, HAPM, Global Home, Castle 10, Build Zone, Build Assure, BLP, Zurich Municipal, CRL, Q Policy or have a qualified Architect’s, Surveyor’s or Structural Engineer’s Supervision Certificate (Professional Consultants Certificate).

  • Maximum starting ground rent on all new build properties with a leasehold tenure is limited to 0.1% of the property value.
  • Ground rent must be reasonable at all times during the lease term. For example, ground rent escalation should be linked to RPI (Retail Price Index) or a similar index, and unreasonable multipliers of ground rent will not be permitted, for example doubling every 5, 10 or 15 years.
