> buying a house with these prices & interest rates, or trying to save for a downpayment while renting.

While there are certainly problems here, higher interest rates drive demand down and lower prices, while lower interest rates drive up demand and raise prices.

Investors tend to look for the best return on investment, the number I often see given is 5%/year. The rent I collect is close to that fraction of the market value of the apartment I own in the UK.

The choice between "rent" and "mortgage" is where the cost of the two is about equal in the first year, which is always a bit unfair on first-time purchasers as (1) they're generally younger and thus earning less money, and (2) the impact of interest payments is always front-loaded towards the beginning of the repayment period.

This in turn means that there's a temptation for very long repayment periods to make it seem easier: in a world of genuinely 0% interest mortgages, paying off a ¤600k over 40 years is clearly easier than paying it off over 20, and lower rates asymptotically approach this.

Conversely, when the interest rate is high enough that (even without paying off the capital and regardless of repayment period) it approximates the rental market rate of the property, this drives down demand. To see why, go back to that previous example of a ¤600k (sale price) property: if the landlord can ask for ¤2.5k/month rent, and the interest rate on a mortgage is 5% AER, then the cost to service the interest without paying capital is the same as you get from the rent — which means investors will ask "why should I buy this?" and renters will ask "why would I want that kind of mortgage?", forcing down the asking prices because the only people still interested are people who can do it without borrowing any money.
