I'm sorry about the stress but to be fair one of the reasons that house prices got so insane was people like you who were buying to rent. That puts pressure on the housing market because if you buy to rent you can own multiple properties, so more and more housing stock gets taken out of rotation so it gets to the point where even if people could theoretically afford to buy a house, there are none available.

Renting brakes the supply and demand system. If there were more houses than there was demand, the value would go down and would open up home ownership for more people, this would increase demand and stabilise the market. If there was insufficient supply, housing prices would go up which would incentivise companies to construct more properties, thus increasing availability and stabilising the market. But the want to be landlords come in and buy up all the available homes and now there is high demand but low supply, so construction companies build houses and sell directly to landlords (because landlords have no chain), demand has increased but supply has remained the same, despite construction having happened. Repeat that for 50 years and you get our current housing market.
