The Mortgage Works has relaxed the affordability assessments it applies to portfolio landlords. 

Nationwide’s buy-to-let unit says it will lift the maximum aggregate loan to value for portfolio landlords, with more than 10 BTL properties, to 75% from 65%.  

The firm will also cut the stress rate used across the portfolio to 5% from 5.25%. 

The Mortgage Works head of specialist lending Dan Clinton says: “As one of the largest buy-to-let providers, the Mortgage Works continually looks at ways to enhance our proposition to serve a wide range of landlord needs.  

“These latest changes follow last week’s rate cuts for larger portfolio landlords. 

Last week, the business reduced rates by up to 25 basis points across its BTL switcher range.
