Or buyer friendly, presumably. You can't tell which based on the ratio, surely.

So it's probably comparing cheap rental properties with expensive owner-occupied properties? That's likely not very useful as a statistic on it's own unless you've got the distribution of both. Better would be making a comparison of the rental price (including charges) vs TCO of ownership for directly comparable properties -- that would be a lot of work.

FWIW 10x price-to-rent isn't far off right in my area of my city in the UK. Houses prices and rental prices are high compared to wages, IMO.
