Rely is a new specialist mortgage lender that has launched in the UK. The lender is focused exclusively on the buy-to-let (BTL) market and aims to redefine the experience for professional landlords by combining a modern, data-driven technology platform with common-sense, human underwriting.
A crucial point for new customers is that Rely is an intermediary-only lender. This means you cannot apply for a mortgage directly with them; their products are available exclusively through an approved panel of mortgage brokers.

About Rely Mortgages
Backed by a panel of institutional investors, Rely was co-founded by experienced figures in the BTL lending industry. Its core proposition is to offer the best of both worlds: the speed and efficiency of a "tech-driven" lender with the flexibility and "human touch" of a traditional specialist.
The lender's stated goal is to provide a "new and improved service" for property investors by using data to streamline the application process, while still having expert underwriters make the final, common-sense lending decisions.

Pros and Cons of a Rely Mortgage
As a new lender, here is a balanced overview based on its proposition.
Pros:
-
Specialist Focus: The lender is built from the ground up to understand the needs of professional landlords, including limited companies and HMOs.
-
Hybrid Model (Tech + Human): Rely's use of technology is designed to make the application process faster and more streamlined, while its human underwriters can make flexible, "common-sense" decisions on complex cases.
-
Experienced Backing: The lender is founded by industry veterans and supported by global asset managers, suggesting a strong financial foundation.
Cons:
-
Intermediary-Only: You cannot apply directly. You must go through a mortgage broker, which is standard for specialist lending but an extra step for some.
-
No Residential Mortgages: They are not an option if you are looking to buy your own home.
-
New to Market: Having launched only recently, Rely does not yet have a long-term public track record or a large volume of customer reviews.
-
Specialist Rates: As a specialist lender, its rates are likely to be higher than standard "vanilla" BTL products from high-street banks, reflecting the complex nature of the lending.
How to Apply for a Mortgage with Rely
You cannot apply for a mortgage directly with Rely as a new customer.
The application process must be handled by an approved mortgage intermediary (broker):
-
Make an enquiry to speak to a broker: We have advisers on our team who specialise in buy-to-let and are on panel with Rely.
-
Broker Assessment: Your broker will assess your full property portfolio and financial situation to determine if Rely is the most suitable lender for your needs.
-
Application Submission: Your broker will then submit your application through Rely's dedicated intermediary portal.
No. Rely is an intermediary-only lender and does not accept applications directly from the public. You must use an approved mortgage broker.
No. Rely is a specialist buy-to-let (BTL) lender only and focuses exclusively on property investors.
This is their core target market. The combination of a tech-driven platform and human, "common-sense" underwriting is specifically designed to handle these more complex BTL applications.
