One of the best collections of Australian residential property analysis on the web has emerged at The Unconventional Economist. Leith's latest article explores changes to housing affordability since the 1970s and the key drivers behind the change.
He summarises the article as follows:
- It is the demand for, and supply of, credit that is the key determinant of house prices. Whilst demand-side factors such as tax concessions, benign economic conditions, and population growth might increase people's willingness to borrow for property, ultimately, if you cannot obtain the finance, you cannot pay a high price. Similarly, tight housing supply would have little impact on house prices when credit is not readily available.
- Lower interest rates and easy credit do not make houses more affordable. Rather, they quickly get capitalised into house prices, increasing the amount that home buyers must borrow.
- When examining interest rates and their effect on housing affordability, it is real interest rates (i.e. the mortgage interest rate less inflation) that matters. Whilst mortgage interest rates averaged a seemingly high 9% in the 1970s, due to high inflation (averaging 11%), real interest rates were negative, resulting in borrowers' mortgage debt being 'inflated away'.
- Importantly, be very weary of offers of more credit and the promise that it will "improve housing affordability". Any scheme that increases home buyer's borrowing capacity, such as shared equity loans and the Never Ending Mortgage, will instead fuel further house price growth, thus eroding affordability.
- Beware the property spruiker. Always be sceptical when reading property-related articles in the press, or when listening to politicians talk about housing affordability. Whilst they might, on the surface, sound reasonable, they are often talking their own book. Instead, think critically about their motives and who their constituents really are.
