Your guide to Keystone for intermediaries

Mortgage brokers, also known as intermediaries, help people take their first step into homeownership. They connect potential borrowers with banks and mortgage lenders to find the most ideal mortgage product for the clients’ situations and preferences. They also guide them through the mortgage process. 

To give your clients the best service, you need a mortgage lender who supports intermediaries and makes complex cases easier to handle. That’s where Keystone Property Finance comes in. They specialise in lending to portfolio landlords and clients who are looking for buy-to-let mortgages. In this article, Mortgage Introducer will discuss what you need to know about Keystone for intermediaries. 

Introduction to Keystone for intermediaries 

Keystone for intermediaries (or Keystone Property Finance) is a specialist buy-to-let mortgage lender. They have an intermediary-only platform where they can work directly with mortgage brokers. Keystone focuses on giving intermediaries all the tools needed to find and complete the right mortgage deals for their clients. 

Keystone for intermediaries is not like your usual high street lender. They offer flexible solutions for cases that might not meet the criteria of traditional banks and other mortgage providers. This includes landlords with large portfolios, clients using limited companies and more. 

Keystone Property Finance: A brief history 

Keystone Property Finance is an intermediary-only lender founded in 2007. According to their website, they were “created by brokers for brokers.” Keystone was launched to offer specialist buy-to-let lending during a period when it wasn’t widely available. 

Over the years, Keystone went through three joint ventures before becoming a standalone mortgage lender in 2018. Since then, they have doubled in size and have strengthened their position in the market. 

Mortgage brokers remain central to everything Keystone does. The company focuses on providing flexible lending solutions, broker-first service, and a platform designed to support intermediaries in placing complex or specialist buy-to-let cases.

How Keystone can help through their online calculator 

Keystone for intermediaries offers an easy and detailed online calculator that can help you quickly work out how much your clients can borrow. You can also compute how much rental income they need for a specific loan size. This tool is designed for buy-to-let mortgages, including: 

  • standard properties 
  • holiday lets 
  • specialist 
  • multi-units 
  • house in multiple occupations (HMOs) 

When using Keystone’s calculator, mortgage brokers will be asked to input their clients’ property value, loan term, and other criteria. You can also select the application type; either an individual (basic or high tax rate) or a limited company. The tool also considers whether the applicant is an expat. Other necessary details include: 

  • your clients’ chosen property’s EPC rating 
  • repayment type (interest only or capital and interest) 
  • the loan term in years 

Once these details are filled in, Keystone for intermediaries’ online calculator works out the maximum loan available, based on the rental income. It also shows the indicative monthly repayment, arrangement fee, and stressed rate. There’s even a comparison of the loan amount exclusive or inclusive of fees. 

You can also filter by the following: 

  • range type 
  • loan type 
  • property type 
  • maximum LTV (loan-to-value) 

There are also fee options to narrow down available products. This can help with faster sourcing of the most suitable mortgage products for your clients.
