Fixer-upper guide: How to renovate an old house



15 January 2022

Transforming a derelict house into a dream home can be a rewarding and potentially profitable experience, plus you never know what you might unearth along the way. Here's how to ensure the road to renovation runs smoothly...

Why buy a fixer-upper?

If you're struggling to find the perfect property, an old house that's a little worse for wear could offer an ideal blank canvas to put your own stamp on.

While taking on a fixer-upper is no small task, breathing new life into a rundown residence can be an especially rewarding experience that offers plenty in return, whether you're yearning for a unique family home or a healthy return on your investment. Beneath the faded fabric, you might even uncover a few hidden gems, from period architecture to a treasure trove of original features just waiting to be revived.

When it comes to your pocket, older properties that are in need of a facelift can often come with smaller price tags. Prospective buyers can be put off by old fixtures and time-worn interiors, so if you're not afraid of a little elbow grease, you could bag yourself a bargain.

For budding developers, a fixer-upper can present the perfect opportunity to create a sizeable profit by renovating a dated home and selling it on to reap the rewards. If this is the case, your budget is likely to be smaller than a homeowner who's working towards their dream family home.

Regardless of your end goal, a successful renovation project requires thorough planning, research and a good dose of creative thinking. Think you're up to the challenge?

How to find a fixer-upper for sale

There are a number of ways you can track down the perfect renovation property. Most obviously, you can take a look at the listings held by your local estate agent or realtor, as well as searching online sites like Rightmove or Zillow. Repossessed houses or residences in a state of disrepair may only be advertised with exterior shots, so it's always worth going to see a property in person to get an idea of the scale of the work required.

Property auctions can be a great way to snap up an older house for less. Check out the websites of your local auction house to find properties going under the hammer in your area or scour country-wide sites like auctionhouse.co.uk or auction.com in the United States. The US treasury also organises property auctions for repossessed real estate.

Whether you bid online or in person, it's important to set a limit and stick to it if you want to bag a good deal. Keep in mind that there's usually an additional fee called a buyer's premium that's payable on top of the hammer price.

Additionally, there's a whole host of more specialist websites out there that can help you find your ideal fixer-upper. PlotSearch and Property With Potential offer great round-ups of listings in the UK that are ripe for renovation, while US sites like CIRCA and Historic Properties can yield plenty of results for heritage homes in need of work too.

Case study: Page Mansion

Like many house-hunters, Abby and Trey Cousins found their remarkable 20th-century home on Zillow. A real project, the property was in a poor state of repair, but the couple fell in love with its historic architecture and storied past. Known as the Page Mansion, everything from the exterior brickwork and crumbling porch to the damp-infested dining room and rubble-filled bedrooms needed a complete overhaul. 

After three years of hard work, the dilapidated building is now a beautiful family home once more. Abby and Trey preserved the home's original spirit and period details, while successfully updating the structure for modern living. All those hours scrolling through property listings certainly paid off!

Assessing an old house

Before you sign on the dotted line, you should always look around a prospective property with a surveyor who can identify any issues to be aware of. These can include potentially costly problems such as subsidence, structural issues and hazardous materials like asbestos, as well as encroaching damp and mould. The surveyor will produce a report detailing these problems and highlight any major repairs and alterations you'll need to carry out.

When access is restricted to a house because it's unsafe, it's still worth inspecting the exterior to get an idea of the remedial costs involved. However, you should be prepared for hidden issues inside the property to wrack up significant costs – don't take a gamble on an unseen house unless you have the budget to cover the worst-case scenario.

That being said, an extreme fixer-upper in need of attention needn't be crossed off your list altogether. It's important to carefully weigh up the pros and cons and make an informed decision. Find out the ceiling value for similar homes on the same street – both Rightmove and Zillow provide averages by neighbourhood.

To avoid making a loss, the combined sum of the house price and the works required should be below this figure. For example, the cost of a simple interior overhaul should be relatively low, while repairs to large features like the roof or foundations could run up significant bills.

You should also check the home's connections, for example, does it have gas, water, electricity and sewage, or will you have to pay to put these in place? Old and long-abandoned properties may not have these services, and where they do, they might not meet modern standards, which could lead to a costly refit.

How to spot – and solve – the most common property pitfalls:

How to finance a home renovation

The cost of a home renovation depends on an array of factors, from the scale of the project to the location and the amount of work you're undertaking yourself. For perspective, a single-storey extension can cost between £40,000 ($48k) - £67,000 ($80k) according to Household Quotes, while removing internal load-bearing walls can cost around £1,200 ($1.4k) - £2,500 ($3k).

The motivation behind your renovation will affect your budget too; if you're creating a long-term family home, you're likely to spend more on the finish, but if you're revamping a house to sell on for a profit, you'll probably be working to a tighter budget.

Top tips on renovating a house for profit:

Whichever route you go down, there are a number of ways you can cover the cost. If you don't have a cash lump sum to fund your project but own another property, you can look into remortgaging. Alternatively, if your fixer-upper isn't in need of structural repair and is otherwise habitable, you may be able to take out a standard mortgage on the property. 

Other options include bridging loans, which can offer fast short-term financing, and renovation mortgages, where funds are released in stages when benchmarks in the building works are met – these can often cover uninhabitable properties too. You can compare renovation mortgages in the UK via BuildStore, or home improvement loans in the US through Investopedia.

Careful budgeting can make or break a project, so you should add round a 15% contingency to your budget to account for any delays or unforeseen problems – don't forget additional fees relating to planning permission and building inspections too. It's also important to get appropriate insurance in place before you embark on your project as your normal policy may not cover major structural work.

Home renovation projects: structural changes

There's a whole range of ways you can transform the layout of an old home, from extending upwards and outwards, to removing internal walls and converting redundant spaces like lofts and basements. 

If your property occupies a small plot and you're working to a tight budget, you might choose to convert an existing garage into an extra living space. On the other hand, if you have a large garden, you could opt for a two-storey extension, though you should consider how your new addition will sit with the original fabric of the building.

Whatever renovation route you choose, you'll need to check whether your project requires planning permission or a building permit. In the UK, some types of extension and renovation are classed as permitted development and therefore don't require planning permission. However, in the US, any project that involves additions or structural changes to your home or its mechanical systems will need a building permit.

Other factors, such as conservation areas and buildings with protected status, may also affect whether your project requires official approval, so you should always check with your local planning authority.

When the project gets underway, it's a good idea to share a schedule of works with your contractors to help avoid miscommunications and costly delays. If you're planning a large overhaul, you may find it easier to enlist the help of a professional project manager or entrust the job of overseeing the works to your main contractor.

After completion, you'll need to get a building inspector to sign off on any structural work, as well as any plumbing, heating, electrical and mechanical alterations.

How to restore period features

When you start to plan your project, it's important to be aware of the distinction between renovation and restoration. A home renovation doesn't have to involve restoration work – the act of returning period features to their original condition – but the two processes often go hand in hand.

Historic features speak to a property's past, and unless they're in an unrescuable condition, restoring them and integrating them into your new home is usually the most respectful course of action. Set within a modern scheme, they can make spectacular focal points and add plenty of personality to a room.

In older houses, features such as ceiling roses, mouldings, beams and original windows may be immediately apparent, however, other heritage gems may not be so obvious unless you know where to look. Intricate tiling and handsome floorboards are often obscured by old-fashioned carpet or lino, wood panelling may be hiding behind plasterboard, while exquisite original fireplaces could be tucked behind modern surrounds, just waiting to be uncovered. Who knows what you'll uncover...

Case study: Rockwell House

Preserving the past was at the forefront of the minds of historic house enthusiasts Ross Sheppard, Jacob Hawkins and Will Walker when they began their meticulous restoration of the dilapidated Rockwell House. Built back in 1838, the sprawling mansion was a crumbling shadow of its former self, but its new owners were determined to bring the forlorn structure back to life.

Focused on saving the home's treasure trove of exquisite period features, they undertook an ambitious renovation project and rescued the local landmark for future generations to enjoy. In the Pink Suite (pictured), the original ceiling rose and cornicing were revived, while the sash windows were restored to their former splendour. Tidied up but preserved in much the same state as when the mansion was built, the hearth is the room's pièce de résistance. Now that's how you respectfully renovate a historic gem!
