When looking for somewhere to live, try not to go for first property you see. Viewing a few will give you an idea of what you can get for your money- you don’t have to settle on somewhere straight away as there are always more properties available in London.
Another top tip is to make a lower offer than what’s listed. Estate agents will often show you properties at the top end of your price bracket, or even a bit above. If you end up liking one of these properties but you don’t like the price then make a lower offer. If it’s been on the market a while, landlords are more likely to accept it, it doesn’t always work but it’s worth a try!
