Mortgage Repayment Guide
Capital & Interest (Repayment) Mortgages
A capital and interest mortgage is a type of mortgage where the borrower makes regular monthly payments that cover both the amount borrowed (capital) and the interest charged by the lender.
Each payment reduces the outstanding balance of the mortgage, with the aim of paying off the entire loan by the end of the mortgage term.
With a capital and interest mortgage, the monthly payments are calculated based on the amount borrowed, the interest rate charged, and the length of the mortgage term. The payments are structured so that the amount of interest paid decreases over time as the outstanding balance of the mortgage decreases.
At the beginning of the mortgage term, the majority of the monthly payment goes towards paying the interest charged by the lender, with only a small portion going towards paying off the capital. However, over time, the balance shifts so that more of the monthly payment goes towards paying off the capital, resulting in a decreasing outstanding balance and less interest charged.
Capital and interest mortgages are also known as repayment mortgages, and are the most common type of mortgage. They are typically seen as a lower risk option than interest-only mortgages, where the borrower only pays the interest on the loan and does not repay any of the capital until the end of the mortgage term.
Interest only mortgages
An interest-only mortgage is a type of mortgage where the borrower only pays the interest charged by the lender on the amount borrowed, and does not make any payments towards the capital (the original amount borrowed). This means that at the end of the mortgage term, the borrower still owes the full amount borrowed and must repay it in full.
With an interest-only mortgage, the monthly payments are lower than with a capital and interest mortgage, as the borrower is only paying the interest charged by the lender. However, because the borrower is not making any payments towards the capital, the outstanding balance of the mortgage does not decrease over time.
To repay the mortgage at the end of the term, borrowers may need to have a separate investment or savings plan in place. This could include savings, investments, or other assets that can be used to pay off the mortgage, or a separate endowment policy that is designed to provide a lump sum payment at the end of the term.
Interest-only mortgages are generally considered to be a higher risk option than capital and interest mortgages, as there is a risk that the borrower may not have sufficient funds at the end of the term to repay the full amount borrowed. As a result, interest-only mortgages are less common than they used to be and are typically only available to borrowers who can demonstrate that they have a suitable repayment plan in place.

15th July 2024Andrew at Thameside mortages has been brilliant in helping us secure great mortgage deals for my last 2 properties. He provides straight forward, honest advise and makes what can be a complex process very easy. Our most recent remortgage has been complex due to our requirements for an expat buy-to-let mortgage, but Andrew has been very thorough and persistent is scouring the market for the best deal that suits our financial needs.
Faris Pervez
16th June 2024Andrew worked very diligently and quickly to secure us a good deal and explained everything in clear and understandable terms. This is the 4th or 5th time I have used Andrew and I would definitely recommend him to anyone - always available, lots of good advice, proactive with the lender trying to push everything through. 5 stars

16th March 2024I worked with Andrew and Laura at Thameside Mortgages when purchasing my first home. The help and guidance I received was fantastic. Andrew was responsive and knowledgeable, and he was able to explain things simply to me. Would highly recommend to any first time buyers! Thank you both.

16th December 2023We were originally introduced to Andrew by a friend and we never looked back following our first introductory meeting. Our purchase was complicated by being based overseas, having an existing property in the UK, and other factors that meant certain mortgage products weren't suitable for our circumstances. Andrew took the time to understand our needs and tailored his advice accordingly, leveraging his comprehensive knowledge of the products available particularly during the fast-changing market as interest rates spiked. His personalised approach and patience ensured we understood the options available and enabled us to structure our purchase in a way that was optimal for us. It was evident that Andrew had our best interests at front of mind to build a trusted and lasting relationship. We'll definitely be using Andrew again when we look to remortgage in the future and for advice regarding the other insurance services he provides.

Can't fault the service we got from Jason and Laura. Highly recommend Thameside Mortgages. Thank you both for your hard work.
Kate Brewer
16th November 2023We were referred Andrew & Laura by a friends who has recently bought their first home and we are so glad they did! As first time buyers this was all new and scary to us but Andrew reassured us and made things so easy every step of the way. He proactively updated us and explained things so clearly. They have exceeded our expectations not just by helping us find a mortgage suitable for us but also sorting out all our insurances making the process stress free. Even once we got the keys to our home we received a lovely new home hamper and the attention to detail was fantastic! Thank you Thameside Mortages!
Jade Leonard
16th November 2023Andrew and Laura have been a great support throughout my (long!) process of buying and selling. Andrew has always made the options available to me in terms of various mortgages or insurance crystal clear so I understand everything clearly as I am not one naturally with a head for figures. It became overwhelming at times but the Thameside team would help break things down so I got a grasp of everything before making huge decisions. My journey to eventually get to my new home was a bit of a rollercoaster but the team were always patient and supportive when I'm sure at times they were equally as frustrated by the challenges as I was. Above all though, Andrew and Laura (and Zoe) are all thoroughly nice people and that in itself is priceless.

Our experience with thameside was very very good. Andrew and Laura were very helpful and supported me and my partner throughout the whole mortgage process which made it a lot easier than we first feared. We would highly recommend thameside to anyone in a heartbeat. We wouldn’t have been able to get through without them both.
Luke Whittle
16th September 2023Massive thanks to Andrew and Laura. Couldn’t fault either of them, helped me throughout the entire process from getting the price range I wanted all the way to completion and making sure my insurance was all set up and everything was ready for when it needed to be! Couldn’t recommend anyone better!
Harry Frolich
16th September 2023Myself and my partner spoke to different company’s before speaking to Andrew and Laura at Thameside Mortgages and was absolutely blown away by the time and effort they put in straight away. They secured us a much better rate then we had previously been offered by 3 other companies and took the time to explain everything to us, as first time buyers we was unsure of the process. Not only securing us a brilliant rate in uncertain times with rates constantly rising but also helping with our life insurance and home insurance policies too. We could not have done this whole process without them and would highly recommend them to anyone in the process of sorting a mortgage!
April Ward
16th September 2023Very efficient and streamlined service. Our mortgage re-application has gone through smoothly and pleased with the service we have received. Would highly recommend.

16th August 2023Excellent and very friendly service! Jason helped me to secure my mortgage and was always super quick to respond. As a first time buyer I found his advice incredibly helpful, throughout what ended up being a very long process after one purchase fell through. Andrew was also very helpful when Jason was on leave. I would recommend Thameside to anybody.

Sam Tait
16th August 2023Excellent service by Thameside Mortgages mainly by Andrew. I got two mortgages recently and Andrew helped me all through the process and got best deals on the market in those tough times. He is very much approachable and answered to all my queries with lots of patience and to his best. He is very knowledgeable and made the whole process smooth and simple. A BIG THANK YOU
D Pingali
16th July 2023Throughout the process, from my initial enquiry and telephone appointment, to his post completion call, I have felt well advised, supported and valued as a customer. With his clear and calm approach, Andrew has a way of making you feel, you are his only client and that nothing is too much trouble, (which is very reassuring to someone whose last mortgage was over 30 years ago). While he was personally recommended to me, I have no hesitation in extending that recommendation further, along with my thanks to him and his team for their excellent service.
Yvonne Savage
16th July 2023Andrew was very supportive throughout the whole process of remortgaging-uploading the documents was easy and communication was excellent. He sorted any issues out swiftly via WhatsApp. I had issues with the solicitor which he was able to sort out and continued to look into after my mortgage completed.

So so impressed with and grateful for the work of Andrew of Thameside Mortgages. He made every step of buying our dream home as easy as it possibly could be. Andrew was the perfect combination of friendly and professional, keeping us informed throughout such a daunting process. We cannot recommend enough. Ben & Hayley.
Ben Driver
16th July 2023A really excellent service in which my advisor (Andrew) took time to really understand my situation, priorities and suggest a product that would work best for me. I really felt treated like a human being - and was shown real patience in how something that feels complicated to me was explained. Andrew asked lots of clear questions and gave me a really clear explanation of what each potential product would mean for me - both verbally and then in writing. Can't recommend highly enough!
Nick Evans
16th July 2023Andrew was recommended to me by my Mum who had recently used him and his team for her purchase. I am 20 so am on a learning curve of what’s involved, and Andrew was a perfect choice for all the support I needed to make my first purchase come true! From initially satisfying the mortgage lender, managing the process, and getting to completion which wasn’t straight forward. My initial offer fell through due to the seller, but Andrew and his team kept me on track with reapplying my mortgage offer to another property and extending so it didn’t expire. This also included guidance on a homebuyer’s report and a huge amount of easily explained detail to helpfully understand the importance of mortgage protection. In addition to my daughter’s review above, as her parent, I’d like to add: Andrew helped myself and partner purchase a property which I have already left a review for, but I also wanted to express my gratitude for helping my daughter. Especially at a time when the climate is so turbulent, as always, Andrew and his team went above and beyond what I have experienced from other advisors. I cannot express enough what an exceptional service Andrew and his team provides. His passion, knowledge and client experience shine at every opportunity adapting to suit your needs. Working in user experience, as a client and from a professional point of view, it is clear Andrew has an exceptionally high level of service that he wishes to deliver to all clients which captures that ‘above and beyond’ experience so well. I am truly grateful for successfully helping my daughter take her first, incredibly important step onto the property market. Sincerely, life changing. I will be recommending and using you again whenever opportunity presents itself. Thank you.
