It seems to me that house prices can be approximated as a function of rents, interest rates (determining required return on owning a house), and anticipated growth in house prices (which again can be decomposed into growth in rents, reduction in interest rates and 'irrational' growth).
Rental yields appear to be around 3.5% at the moment, which suggests to me that a good deal of anticipated growth is priced in. But where can that growth come from? Rents are a function of incomes and are unlikely to outpace inflation. Interest rates seem to be more likely to go up than down. So it seems that house prices are unlikely to rise, and once that is realized by the market, prices may even come down as participants stop anticipating growth just because "London house prices always go up".
House prices going up faster than rents in recent decades can probably be explained by interest rates being in a downward trend over the same decades. Now we seem to be in at least somewhat of a bubble due to irrational future growth expectations.
