There's lots of economics here - not least the macroeconomic implications of a concentrated housing market. However, the crux of this issue is that there are worries that the housing market is increasingly dominated by a small number of large firms and that this might be responsible for a market failure.

Have a think: why might such a situation arise - I'll give you a clue, think about the price/output levels of perfectly competitive and monopolistic markets.
