Is BTL still possible?

[Boom78]

Hi guys
I’ve been considering buying a small 2nd house or flat in my local area to rent out, ideally on a repayment mortgage plus deposit. The ultimate goal isn’t an income but to have a 2nd property purchased and paid off in X years as a future investment. Eg sell off.

Is there still a market for mortgages for this sort of thing? What killed the old BTL market? Was it just people trying to unsuccessfully make monthly income
