If I read the translation right, and I am unsure of the possible ramifications, it "might" actually be good to lower rent regions to 20 rather than 29.
There are certainly places who charge such nowadays...which doesn't mean it is necessarily a good thing to do, though.
Even still, it takes a certain kind of person to rent such here who are not fettered by the SL -think and used to being catered to by grid owners. A more independent type of person.
I would be happy to promote such a decrease as best I can, of course, tho mostly in g+.
