Can massively, massively depends. With massive caveats.
Scroll up to response #2356 (and the follow-on) for my general two penneth.
More specifically, consensus for Glasgow, that I’ve come across, seems to be that up to 10% over the survey valuation isn’t uncommon in a popular area, and it can go beyond that without to much. Can be more than that, too, but i’d advise you to carefully consider exactly why you’re willing to go that high (or even over the valuation at all), to make sure it’s for trains more substantial than just because you simply want to stand a chance of getting it.
A year ago we bid 13.5% over the valuation (cos we intend this to be our home for probably a couple of decades or so and it fit the bill for what we wanted EXACTLY, with cherries on top) and apparently weren’t quite the highest, but the seller accepted our offer anyway (because I suspect he saw his younger self in us, compared to, maybe, a BTLer)
Ultimately, offering over the valuation is likely to mean that you’re deferring the accumulation of equity in the place° (and, if this is a first time buy) maybe accepting that you’ll be in negative equity for a bit. But something to be taken lightly, but if you KNOW it’s somewhere you’ll be for a while (or that you can specifically add value in some way) and your employment/income is secure, then you may be able to justify out.
Even further up the thread I’ve said she stuff about how utterly mad the psychology of second and third guessing what the imaginary other bidders will offer. Ultimately it comes down to you offering what it’s worth to you. There’s the risk that you’ll offer a substantial wedge more than someone else, it’s true, but if you’ve done the research on the local market and keep a cool head, you’ll not end up mugging yourself. Which is pretty standard across the board, really. Even when it’s not closed bids.
Good luck.
°disclaimer: deferring the assumed accumulation of equity in a place can be something you unwittingly get caught up in even if you’ve offered nothing over the survey valuation (or bought a place below survey valuation), if the local or national housing market as a whole takes a hit. Which isn’t exactly a risk to be completely ignored, considering our precarious Brexity economic future and the state of the UKs finances in general.
