What is a Buy to Let Portfolio Mortgage?


Coreco are proud to be one of the most experienced Buy-to-let mortgage brokers in the London mortgage market – some of our advisors were around when the modern residential Buy-to-Let mortgages were initially launched.

This product offers one umbrella mortgage for more than one Buy-to-Let property, rather than having a mortgage on each property.

This removes the need for multiple mortgages with different lenders. One lender will finance the portfolio loan with one monthly payment and one statement. This makes things much easier to manage as a landlord.

 

What makes it different from a normal buy to let mortgage?

A Buy-to-Let portfolio mortgage is a product designed for landlords with at least four investment properties. Each lender will have their own lending policy on the number of properties or the total value within a single portfolio mortgage.

Our brokers are familiar with portfolio lenders’ criteria and are happy to advise and find a suitable lending option based on your portfolio requirements. Lenders will view and assess each property portfolio based on its own leverage, structuring and tenancy types.

We have advised on portfolios in excess of 50 properties, with complicated group/subsidiary structuring.

 

Portfolio Stress Testing (ICR Requirements)

Most experienced landlords can get a Buy-to-Let portfolio mortgage however, in 2017 new mortgage underwriting regulations from the Prudential Regulatory Authority (PRA) came into effect which impacted the criteria. With the new regulations in effect, lenders must treat you (for underwriting purposes) as a portfolio landlord if you have four or more mortgaged properties.

Lenders will apply slightly higher ICR (Interest Coverage Ratio) to your current lending and new proposed lending.

Portfolio lending can have a degree of affordability applied to the underwriting to mitigate any rental void periods, that there is sufficient income/s to service the proposed lending.

Typical requirements:

  • Property income – Tax documents (Accounts)
  • Any other income – Personal Tax Documents (Tax Year Overviews & Tax Calculations)
  • The amount and source of Deposit
  • Equity – via valuation reports
  • Your credit history

When it comes to buy to let and portfolio mortgages there are other considerations that the lender will take into account. Different lenders will conduct different checks but things to be prepared for include:

  • A stress test of your portfolio
  • Assets and liabilities evidence, including tax liability
  • Evidencing details of all mortgages on your buy-to-let properties

FAQs

  • Who can get a Buy-to-Let portfolio mortgage?

    Most experienced landlords can get a Buy-to-Let portfolio mortgage however, in 2017 new mortgage underwriting regulations from the Prudential Regulatory Authority (PRA) came into effect which impacted the criteria. Previously, portfolio landlords were classified as full-time landlords if they owned multiple Buy-to-Let properties, student accommodation or houses in multiple occupancy (HMO).

    However, with the new regulations now in effect, lenders must treat you as a portfolio landlord if you have four or more mortgaged properties. In addition, the portfolio must be registered as a limited company and treated as a business.
