Durham has one of the strongest student rental markets in the country, driven by Durham University, one of the most prestigious universities in the UK. Student demand is consistent year on year, making Durham a popular destination for buy-to-let investors looking for reliable rental income.
Beyond the student market, Durham City and the wider county attract young professionals, families, and commuters who need good quality rental accommodation. If you are looking to invest in Durham property, whether it is your first buy-to-let or you are growing an existing portfolio, we will find the right mortgage to make your investment work. Visit our Buy to Let page for more information.
Running your own business should not stop you from getting a great mortgage. We work with lenders who genuinely understand self-employed income, whether you are a sole trader, contractor, or limited company director. We know how to present your application in the strongest possible light. See our Self Employed page for more details.
Past credit issues do not have to hold you back. We have access to specialist lenders who look beyond a credit score and consider your full circumstances. If you have been turned down elsewhere, it is worth a conversation with us before you give up. Our Bad Credit page explains your options in full.
Upsizing, downsizing, or relocating within Durham or the wider North East, whatever your situation, we will take the stress out of the mortgage side of things so you can focus on the exciting part.
Going direct to a bank means you only ever see one lender's products. Going to a comparison site gets you a bit closer but still misses a significant chunk of what is actually available. Working with The Mortgage Dog gives you the full picture.
Our advisers search across the complete range of lenders, from major high street banks through to specialist providers who do not advertise directly to the public. Whatever your situation, whether you have a complex income, some past credit issues, or are buying a non-standard property such as a listed building or a property near the university, we know which lenders are most likely to say yes and at the best rate available.
We cover every type of mortgage including first time buyer, home mover, remortgage, buy-to-let, self-employed and bad credit. We also offer mortgage protection insurance to make sure your home and family are properly covered if the unexpected happens.
We are based in Washington, roughly 20 minutes from Durham City by car, and we offer face-to-face appointments, evening and weekend availability, and remote appointments by phone or video call. Whatever works best for you is fine by us.
We serve buyers and homeowners across the whole of County Durham, including Durham City, Newton Aycliffe, Consett, Spennymoor, Bishop Auckland, Stanley, Chester le Street, and Seaham. We also cover neighbouring areas including: Gateshead, Sunderland, Newcastle, and Washington.
County Durham has one of the most interesting property markets in the North East. Average house prices across the county sit around £138,000, making it one of the most affordable areas in England and a genuinely attractive option for first time buyers who want to keep their costs manageable without sacrificing quality of life.
Importantly, house prices in County Durham are growing faster than the wider North East average. Prices rose by 4.3% in the year to January 2026, compared to a North East average of 2.2% over the same period. That upward momentum makes it a compelling market for buyers and investors alike.
Durham City itself is one of the most beautiful and historic cities in England. The Cathedral and Castle, a UNESCO World Heritage Site, sit dramatically above the River Wear on a rocky peninsula in the heart of the city. Durham University brings a large, well-educated population and consistent rental demand. The city has excellent rail connections, with regular fast trains to Newcastle, York, and London Kings Cross, making it popular with professionals who commute further afield.
Popular areas for buyers in and around Durham City include Framwellgate Moor and Nevilles Cross for families, Gilesgate and Claypath for young professionals, and the city centre itself for those who want to be close to everything. Further out across the county, towns like Chester le Street offer excellent commuter links to both Durham and Newcastle, while Barnard Castle and the surrounding Teesdale area attract buyers looking for something more rural.
The rental market across the county is strong. Private rents rose by 6.6% in County Durham in the year to February 2026, driven by a genuine lack of supply across all property types and consistent demand from students, professionals, and families.
