Stephen Davison, 61, from Llandudno, Conwy county, lost his job during the pandemic and has to use his savings to pay his bills.
His rent has gone up £100 a month which, in addition to repeated council tax in recent years, has made paying his bills more of a struggle.
He said: “You go from having made some plans for the future to having everything thrown up in the air. I don’t know where I will be if I can’t get another job.
“My savings are going down, my prospects of getting a job are going down and you feel insecure.”
Estate agent Douglas Haig, a director of the National Residential Landlords Association, said he expected rent increases in Wales to taper down as a number of cost increases for landlords “have started to bed in now”.
He added: “It gets to a point where there is a there’s a ceiling on what the general market can afford. And I think we’re getting to that point.”
