Exactly, supply and demand as pp’s have said.
My db had his house valued for rental at £1200pcm when he moved in with his gf. It languished on the market for a bit so he let it for a bit less to a nice couple.
If he let it out for say, £600pcm just to cover his mortgage it would be an extremely bad idea as his other costs wouldn’t be covered - he’d be better off just letting it stay empty and not taking the risk.
They’ve been there a year now and he’s actually spent more money than he’s gained - part of a garden wall fell down and cost £10k to re-build and he’s had to install a new shower and extractor. There is a small pool of water that keeps appearing in the bathroom and he’s had a plumber out several times. The plumber thinks it’s just that the tenants aren’t using the shower curtain correctly and are airing their wet laundry in there but they won’t listen. He’s not renewing the contract when the time is up as he’s found it very stressful.
The rental market is the only business where people seem to be expected to take huge personal risks and not gain financially. Why would you bother if there wasn’t a profit to gain? Would you rent your house to strangers out of the goodness of your heart knowing they could completely trash it and you’d never see any money back? Or that they could refuse to leave and you’d have to spend £££ going through court to get them out? Or that something as trivial as the batteries running out in a smoke alarm could leave you paying thousands in fines?
One LL I know had an alcoholic tenant who fell down the stairs and blamed a loose handrail (unreported) on his fall and took the LL to court (all free via legal aid of course) He ended up settling as it wasn’t worth the stress and time of his solicitors costs. He then had a long battle to get this person out of the flat despite many complaints of antisocial behaviour from other tenants.
Situations like this are a really common occurrence and the increasing difficulty getting rid of troublesome tenants is understandably putting small LL’s off.
