I get your point but equally landlords snapping up houses does cause issues. When I wanted to move from renting to owning it took 2 years to find somewhere in the area I wanted to live, well less wanted to and more needed to due to parental caring responsibilities.
There was a recurring pattern. Property would appear on the market, you'd book the earliest available viewing and then before you had chance to look your viewing would be cancelled as a buy to let landlord had put in an offer without viewing it.
IMO a large part of the reason landlords get accused of profiteering is how high rents are compared to mortgages, when I moved my mortgage was half what I was paying in rent for a house on the same street - and even now after the hike in interest rates its still lower than my rent was. Now that would be fine if properties were well maintained and landlords responded to issues in a timely manner but speak to pretty much anyone who has rented and they will tell you about problems with getting the landlord meet their responsibilities.
You can walk round the area I live and easily pick out which properties are rentals just by looking at the state of them.
There is little financial benefit for most small/accidental landlords these days. I was reading an article the other day, lots are selling up or planning to. Very few new properties are bought by landlords
Most of the BTL properties being sold are bought by owner occupiers, this reduces the amount of properties available on the rental market. Add this to the lack of building and huge increase in population (I’d imagine a significant proportion of those moving to the U.K. are unable or unlikely to want to buy, especially in the short term), together with various governments policies* to make BTL less profitable/harder, plus recent interest rate rises, have unsurprisingly pushed up rental prices
You also get probably the more honest landlords who pay for repairs, improvements knowing that they just can’t make money exiting the market. Those that don’t give a fuck and ride their luck providing poor accommodation, carry on.
These are the unintended consequences that happen with a lot of well meaning policies….the real world gets in the way
*many of which I agree with but needed to happen alongside other policies to increase housing supply
