This would be a good open data project!
This Canadian company (
http://www.caprent.com/About_Capreit/)
has purchased a number of properties in Dublin that have become
available on the market super cheap as a result of the crisis. Property owners bought at inflated prices here, the economy tanked and numerous bankruptcies ensued making thousand of properties available dirt cheap. They
are now increasing rents by up to 26% without any upgrades, one of my colleagues is one of their tenants.
Have you head of this company? In Canada they own "41,552 residential units, comprised of 35,372
residential suites and 29 manufactured home communities comprising 6,180 land lease
sites located in and near major urban centres across Canada and Dublin, Ireland"
Clearly
they do not behave here as they are obliged to at home. Also, the high
number of properties means they set the market value!
A map of who
owns what rental and condo properties would be interesting and might reveal owner concentrations.
