No doubt. But ceteris paribus, that is of primary interest to many investors. But maybe you can elaborate instead of making sphinx-like pronouncements.
Primary? For investors who know their stuff it is of significant interest. Prices are far more important (and house prices roughly follow demographics, so are dropping in many places)
Swell. Can you tell me where all these properties are where the rent covers the mortgage payments? It would be even better if you could highlight the ones where the rent also covers insurance and taxes. Since there are plenty of the former, I'm sure the latter subset is also pretty easy to find.
