NatWest Buy to Let Agreement in Principle
What is an Agreement in Principle?
A NatWest agreement in principle is the first step to securing a buy to let mortgage. When you receive an agreement in principle from NatWest, it is an indication that they are prepared to lend the amount required for your project. NatWest comes to the decision by reviewing your credit and completing a brief affordability check. This may be done online or in your local Natwest branch.
What Do I Need For the Application Process?
Getting an agreement in principle is a relatively short process, which can take as little as 5 minutes. For NatWest to make their decision they will need:
- A small amount of personal information
- Some details of your income
- An outline of your financial commitments
It is important to note that under no circumstances will the lender use the aforementioned details for marketing purposes.

Getting an agreement in principle requires no commitment from you. When you receive an agreement in principle you can review NatWest’s range of rates and apply for a mortgage. Remember, if you have an agreement in principle, you are under no obligation to apply for the mortgage.
The process is straight forward and NatWest can even provide an agreement in principle through an online application. You should note that an agreement in principle for a buy to let can be accessed online, but not a Help to Buy, Right to Buy, shared equity, Offset or interest only mortgage.
