Why is there demand?
Because successive Governments have introduced policies that make being a casual landlord impossible.
The result is less rentals, more competition and higher costs.
In Cardiff circa 2005, you could rent a two bed maisonette, withing spitting distance of the City Centre, for less than £500pm. Or you could pay over a grand for a flat "down the bay". You could, I shit you not, pay £200 quid a month for a converted garden shed down the back end of Pontcanna. But the Governments didn't like this, too easy to make a bit of tax free income. So they banned it. And the new Renters Rights Bill will kill the market completely.
From now on, the only players in the rental game will be big corporate landlords. Lloyds Bank has bought up over FIFTY THOUSAND residential properties in the UK over the past three years!
But "Doing Well Dave" who wants to buy his fifth terrace to rent out on the cheap to local students is suddenly the scum of the earth.
I have ZERO sympathy for renters who are now complaining about cost. You had years to fight your corner and support the small local landlord. You didn't. You just wanted more and more, and supported the Government in hounding them out od the market. Well now you have nothing. Well done!
