A surprising number of renovation mistakes do not happen on site.
They happen before a single contractor is booked, before a single quote is requested, and before the keys have even changed hands. They happen at the planning stage, or more accurately, because there has not really been enough planning at all.
And one of the most common of those early mistakes is going into a project without being properly clear about what you are actually trying to achieve.
That sounds such a basic point that it almost feels too obvious to mention, but in practice it matters a great deal.
Over the years I have come across investors who bought a property, started the work, and only then began to realise that they had never really thought through the end market. Were they doing it up to sell on, or to keep and rent out? Were they aiming at owner occupiers, other investors, or tenants? Was the standard of refurbishment they had in mind actually appropriate for the sort of buyer or occupier they were likely to end up with?
By the time those questions are asked properly, decisions have often already been made and money already spent, and those decisions are not always easy to reverse.
That is why I have long felt that one of the most reliable early warning signs of a project that may struggle is when the investor cannot give a clear, simple answer to a very straightforward question.
What exactly are you trying to achieve here?
If that answer is vague, a lot of the rest of the project can become vague as well.
This is where it tends to go wrong in practice.
If you are renovating to sell to an owner occupier, the standard of finish will usually need to be higher. Owner occupiers are buying a home. They want to imagine themselves living there. The kitchen matters. The bathroom matters. The overall feel of the place matters. A property can be perfectly sound and perfectly respectable, but if it does not feel right to that market, it may not achieve the result you were hoping for.
If, on the other hand, you are renovating to sell to another investor, that is a different proposition altogether. Other investors are not usually buying a dream home. They are buying a yield, or a return, or a project that they think works at the price. They want a sensible refurbishment, a property that is lettable, and ideally a price that still leaves something in it for them. Spending heavily on a premium finish for a buyer who mainly cares about the numbers is often money you did not need to spend.
If you are renovating to let out, that is different again.
You still want the property to look good, of course, but the emphasis is usually more on sensible, hard-wearing, practical finishes. You want something that will attract decent tenants and stand up reasonably well to use. There is often no point spending money on things that look lovely on day one if they are likely to be scratched, chipped or worn far too quickly in normal use.
And then there is the model which, where the figures allow, I have often liked a great deal myself: refurbish the property, let it out, refinance it, pull back out as much of your money as possible, and then use that money again on the next project.
That also affects how you think about the job, because you are not just looking at whether the property will sell or let. You are also thinking about what the valuer is likely to make of it once the works are done, and whether the money you are spending is actually helping you achieve the end result you want.
Each of these scenarios points you towards different decisions about what to do, how much to spend, and what to leave out.
They are not interchangeable.
And that is why it is dangerous to drift into a refurbishment without being clear about the destination. If you do that, you can easily end up in a sort of muddled middle ground where you are over-specifying for one market, under-delivering for another, and spending money in places that do not really move the needle.
There is another angle to this as well, which does not get talked about enough, and that is refurbishing between tenancies.
A lot of investors think of that as a bit of touching up, perhaps a lick of paint, a clean, and a few repairs. Sometimes it is. But if you hold property for long enough, sooner or later you are likely to need something more substantial than that. So even if the property is being refurbished as a rental from the outset, it is worth thinking carefully about how the original choices you make may affect what needs doing later.
The point, really, is that the reason behind the refurbishment shapes almost everything that follows.
It shapes the specification.
It shapes the spend.
It shapes the likely end value.
And it shapes what success actually looks like.
That is why I think one of the most useful things you can do before you buy, before you get quotes, and before you make any decisions about where the money should go, is stop and ask yourself a very simple question.
Who is this property really for once the work is done?
What do they want?
What will they pay for?
And what can be left out without hurting the outcome?
If you answer those questions clearly at the beginning, a lot of the rest becomes much easier.
If you do not, there is a fair chance you will be making it up as you go along.
And that is an expensive way to learn.
