Also let it be noted that the worldstaff are currently working on new districts in regalia which will include more properties. So the issue of not having properties to rent should be fixed in due time.
There are 4 districts that are being worked on, with a ton of houses in each of them. Obviously they take time to become beautiful before being released. Great response!
As for the OP's original idea of reducing the rental limit to 1 house, I'd have to completely disagree with it. For example, I own 2 regions. One is a shop in the harbor district, the other is a summer estate. I use both to fulfill my RP needs. If either of them were removed form my ownership, I'd lose out on resources for my RP.
And if this rule was added, you can already bet that people will use their alts to rent the regions and then just add their main accounts to the region.
If you really need a region, I'd suggest finding a house that looks rather empty, and ask if the owner would be interested in selling. This is really useful to do if the rent is gonna expire soon, and the owner has few regals. Or possibly find someone who rents out part of their region as apartments or hotel rooms. They might like to have someone share rent.
TL;DR there are more rentals coming, and forcing people to lose regions will just cause more people to leave than stay. The rule of 2 rentals per person is a good rule. Also, there are always house auctions available on the forums.
