I don't know anything about Strike and I'm not selling atm so I don't care, but I've got to say I'm fed up to the back teeth of people extolling the virtues of a "good high street agent" when there basically aren't any.
Most EAs are part of chains that regard house sales as a necessary evil to access the core business of flogging mortgages and other financial advice, and couldn't care less about what your house sells for because the business as a whole values the cashflow and business forecastability of pushing through unremarkable sale after unremarkable sale more than it values the extra hundred quid they get from each extra £10K they persuade out of everyone's buyers. And my personal experience of independents isn't any better tbh, though I would rate them more as a buyer because of their local knowledge.
The fact is that most HS agents are at best a mediocre lot and are often useless, worse than useless, or positively corrupt. It's hard to know whether Strike/Yopa/PB etc can be relied on not to scam you, and of course as sellers we all want the coveted RM listing, but in every other respect I would say I could do a better job of selling a house myself without the 'help' of some undereducated wide boy variously failing to pass information on or alternatively just forwarding emails between buyer and seller unedited. It's pretty simple. You just take decent photos, make the place nice for viewings, be reasonable but not a doormat, communicate regularly with your buyer, prod your solicitor as often as you feel necessary, and make sure the money is definitely there before you take the place off the market. As an optional extra, have a word with yourself about the amount of aftershave you consider appropriate. More EAs than I can shake a stick at don't manage this simple checklist and many don't manage any of it.
If anyone really does come across a "good high street agent" then please, name them and let's all benefit.
