The buy to let mortgage calculator offers a helpful estimate based on your rental income and property value, but it’s only a guide.
Lenders take additional factors into account, such as your credit history, personal income, and overall financial situation, which the calculator can’t assess fully.
To get a more accurate figure and access to the most suitable mortgage deals, it’s recommended to speak with a mortgage broker like us.
We can help you navigate the complexities of buy to let mortgages and find a solution tailored to your investment needs.
Interest rates play a crucial role in determining your monthly mortgage payments, especially for a buy to let mortgage.
Higher interest rates increase the cost of borrowing, meaning your monthly payments will be higher, which can reduce your rental yield
If you have a tracker or variable rate mortgage, your payments will fluctuate based on changes to the Bank of England’s base rate.
For stability, many landlords opt for fixed-rate buy to let mortgages, locking in their payments for a set period.
Speaking with a mortgage broker can help you explore the most suitable rates available for your buy to let investment.
Your loan value decreases over time as you make your monthly mortgage payments, with each payment contributing towards both the interest and the loan balance (the principal).
The speed at which the loan decreases depends on the type of mortgage you have. With a repayment mortgage, each payment gradually reduces both the interest owed and the principal, so your loan balance decreases steadily.
With an interest-only mortgage, you’re only paying the interest each month, meaning the loan balance remains unchanged until you repay the capital in full at the end of the term.
Your loan value over time is determined by several factors, including the type of mortgage and how much capital you repay each month
For a buy to let mortgage, if you choose an interest-only deal, your loan amount will remain the same until the end of the term, as you only pay the interest each month.
With a repayment mortgage, each monthly payment reduces both the capital and interest, meaning your loan balance decreases over time.
To understand which option suits your long-term property investment goals, speaking with a broker can provide tailored mortgage advice.
For a buy to let mortgage, most lenders typically require a minimum deposit of 25% of the property’s value, though this can vary based on your circumstances and the lender’s criteria.
Some may ask for as much as 40%, especially if you are looking for better interest rates or have a more complex financial situation.
A larger deposit can help you secure more favourable terms.
Speaking with a mortgage broker can help you explore your options and understand how much deposit you’ll need based on your investment goals.
Using a mortgage broker for your buy to let mortgage is highly recommended.
Mortgage brokers like us have access to a wide range of lenders, including specialist buy to let deals that may not be available directly to landlords.
We can help you navigate the often complex requirements, such as rental income calculations and affordability assessments.
By working with a broker, you’ll save time and have a better chance of securing a competitive rate, while ensuring the mortgage suits your investment strategy.

First time buyers anxiety and unknown was made super comfortable and simple by using The Moneyman mortgage advisors. Conor and Stacey are a dream duo! Although we happened to start the search for a lender during the 2026 unexpected world conflicts, the pair worked tirelessly to get us the best rate possible and take the stress away! Would recommend again and again *****

Tom at Cardiff Moneyman is a superb mortgage broker, extremely professional and gave step by step guidance through my successful first time buyer mortgage application. He answered any questions I had within minutes of sending an email. Special mention to Stacey, who again was extremely professional and provided great attention to detail. I could not have been happier with the process and would highly recommend them to anyone looking for reliability and thorough professionalism.

I worked most closely with Paula and Dinah at UK MoneyMan to get a mortgage as a first time buyer. They were both friendly, helpful, professional and kept me updated at all times. And most importantly they got me a mortgage that works for me after years (decades!) of trying to get onto the property ladder. Thank you UK Moneyman
