The average homebuyer only owns their kitchen and bathroom once they take out a home loan on a new home, according to new information from MoneySupermarket.
The comparison site also states that the average buyer removes a mortgage for 67% from the value when they purchase a property.
Here, we look at just how different regions of the UK compare and reveal the very best mortgages available if you have a first deposit of 30% or even more.
How your main home do you really own?
The average British homebuyer owns 33% of their property when they first complete on the purchase, equal to an average-sized kitchen and bathroom.
They buy the property using an average mortgage of lb75,395, based on MoneySupermarket.
With each square metre of the average UK property costing lb3,248, the findings demonstrate that the biggest room in the house – the living room – is the most valuable space, and the master suite may be worth almost lb3,000 a lot more than the kitchen.
| Room type | Average UK room size | Average UK room cost |
| Living room | 17.09 sq m | lb55,519 |
| Kitchen | 12.61 sq m | lb40,965 |
| Bathroom | 5.55 sq m | lb18,030 |
| Master bedroom | 13.37 sq m | lb43,434 |
| Second bedroom | 10.88 sq m | lb35,345 |
| Third bedroom | 8.32 sq m | lb27,029 |
The researchers also calculated average individual room costs in main UK cities based on the average house price in every location.
According towards the analysis, a London family room is worth lb45,000 more than one in Glasgow.
| Location | Master Bedroom | Second Bedroom | Third Bedroom | Bathroom | Living Room | Kitchen |
| London | lb69,430 | lb56,500 | lb43,206 | lb28,821 | lb88,748 | lb65,483 |
| Glasgow | lb34,099 | lb27,749 | lb21,219 | lb14,155 | lb43,587 | lb32,161 |
| Cardiff | lb40,000 | lb32,550 | lb24,891 | lb16,604 | lb51,129 | lb37,726 |
How on earth did they work that out?
Researchers at MoneySupermarket checked out average room sizes in 10,000 homes built because the 1930s using data from Rightmove and Zoopla, and combined this with the average UK house size according to LABC Warranty (67.82 sq m).
They then used MoneySupermarket’s own mortgage data to work out average house prices in various areas, and after that calculated how much each square metre inside a typical home costs and what this means for different rooms.
North/South divide
Property owners within the North were paying less but owning more in an earlier stage, based on the research.
The table below shows how much could have been paid and owned in various regions of the united kingdom after five years.
After five years a homeowner in Leeds would own 41% (lb78,858) of the value of their house, which is equivalent to a bedroom and kitchen. However, by this stage a house owner in Edinburgh would own 61% (lb204,749), equal to three bedrooms and a family room.
Unsurprisingly, the typical deposit put down varies from city to city, meaning buyers are in another position right from the start of their mortgage term. Here’s how London and Edinburgh compare during the period of Ten years.
Best 70% mortgage options
As the average homebuyer reportedly owns a third of the property once they complete on a mortgage, they may be interested in 70% loan-to-value (LTV) mortgage deals.
An LTV is when a mortgage you have with regards to how much the property may be worth, expressed like a percentage. For example, should you took out a lb150,000 mortgage on a house worth lb200,000 you'd come with an LTV of 75%.
Here are some of the best 70% LTV deals on a two-year fixed-rate basis, by initial rate.
Best two-year fixed-rate 70% mortgages
| Provider | Initial rate | Revert rate | APRC | Fees |
| Halifax | 1.49% | 4.24% | 3.8% | lb995 |
| HSBC UK | 1.49% | 3.8% | 3.8% | lb699 |
| Sainsbury’s Bank | 1.53% | 4% | 4% | lb995 |
