Frequently asked questions

Having a Buy-to-Let property can be like running your own business, which means you need to pay close attention to all costs. A Buy-to-Let mortgage calculator can be a valuable tool to help you understand how much you could borrow. Simply answer a few questions about your situation and plans, and our calculator will provide a guide on your potential borrowing amount.

This information allows you to plan in detail and ensures you are prepared when applying for a mortgage. It’s important to note that the figure provided by our Buy-to-Let mortgage calculator isn’t exact, as the amount can vary between lenders. Therefore, it’s best to discuss your situation with an expert mortgage advisor.

Assessing affordability is crucial for lenders for two primary reasons. Firstly, it provides them with an essential indication of how much you can afford to borrow, considering that you’ll need to repay them over time. Additionally, it serves as a measure of how profitable your Buy-to-Let property is expected to be, as the rental income is often utilised to cover mortgage payments to the lender.

While residential mortgages typically assess income and outgoings during the affordability assessment, Buy-to-Let mortgage affordability criteria differ slightly. Lenders still consider your income and outgoings, but they also factor in projected rental income. Since interest payments are part of the equation, the rental income should exceed the mortgage interest by a specified margin.

Usually, lenders require the rental income to be anywhere from 125% to 145% of the mortgage interest payment, assuming an interest rate between 5% and 5.5%. It’s advisable to be prepared for higher rates, especially when applying for an HMO Buy-to-Let.

During their assessments, lenders always conduct a stress test to ensure that you can make payments even if interest rates rise. However, if you opt for a fixed-rate mortgage for five years or more, calculations are based on the following:

  • A hike of at least 2% above current rates.
  • Market projections of future interest rates.
  • A minimum stress-test rate of 5% – 5.5%.

You can use our buy-t0-let mortgage calculator to gain an understanding of your borrowing potential.

If you have a property in mind, then you are likely to have an idea of how much rent you will charge. However, lenders won’t take your word for it. Therefore, they will use a surveyor to calculate this based on things such as the property value, market rates and location.

Lenders will also consider any void periods that may arise during ownership to keep things as realistic as possible. Typically, they assume there will be no tenants in the property one month out of the year.

During their affordability calculations, lenders may also factor in property-related expenditure, deducting it from the rental income. This can be costs such as letting agent fees, insurance, safety check costs and any maintenance fees.

Finally, an important consideration is the lenders imposed Loan-to-value (LTC) limit. This is set and will put a cap on how much they will lend. A maximum of 75% is very common for most lenders, although some do offer more.

Always remember that lenders will place their products in LTV tiers. Meaning, if you can provide a larger deposit, you are more likely to receive better interest rates.

Using Ipswich Mortgage Centre for my property purchase was really easy and gave me the security I needed for a big decision. Ciaran was fantastic in providing me with information on the options available to me and ensuring the whole process ran smoothly. If there were any issues, Ciaran quickly stepped in to clarify and supported me through each step to ensure the transfer happened on time. Thanks for all your help. I would highly recommend working with Ciaran!

Highly recomend using Will, I have spoken with him over the last year and a half for advice whilst buying my first property. Friendly, approachable and very helpful for pointing me in the right direction. Although I was declined through several lenders Will persevered and found a lender that approved me. Finally moved in a month ago and feel this would not have been achievable without him.

Mark Gardiner was my mortgage advisor and honestly he was amazing throughout the whole process. Before Mark contacted me I was at a complete loss as to whether I would ever own my own home due to other mortgage affordability calculators with other organisations. Mark spoke everything through with me at every step of the way, and answered every single one of my questions (there were a few, as I knew absolutely nothing about the process of buying a house!). Mark always made himself available to speak to me, I feel like he went above and beyond for me and my situation, which I really did appreciate. I do not have the right words to describe my gratitude to Mark, if it wasn’t for him I don’t think I would be sitting in my very own house right now. I had such a fantastic experience because of Mark, i would recommend him and your organisation to anyone looking to purchase a house, especially if you are a first time buyer. I just wanted to express my gratitude, and to ensure that Mark gets the acknowledgement for all of the time and effort that he put into my case.
