From what I remember, there is a very different concept of ownership in this society. The land in Jehna was "owned" be the heads of the respective tribes, not by the people who lived in a given house. My guess here would be that everyplace is owned by the Council of Tyrants (CoT).
From the description of the Sanctum, which I believe was "hastily constructed," I saw a house in the slums which had been converted to use as a Sanctum. Probably not very nice, but servicable.
As far as having my home fixed up. If I was going to do that, I'd have to pay for it myself, not collect donations to help the poor refugees and the Mindless, and then use it to fix up my home. Seems a bit like a bait and switch, which is what Ajax's previous experiances are going to force him to see it as, if it happens.
If the cleric uses his money to make the church pretty while the rogue uses his money to feed the hungry, well, that's a bit skewed. Perhaps if all of Jehna's refugees were fat and happy, I could see funds being directed to the sanctum, but that really has to come last.
Also, I have to wonder if the guy who runs the White Sanctum will be very keen on having anything more than a temporary structure of another sect. He's been very understanding so far, but a permanent building might be seen as an attempt to encroach on his territory. It seems like the refugees are going to be here for the forseeable future. In fact, depending on how many men die in the guerilla war in the mountains, there may not be enough to sustain a viable town at the war's end.
While I suppose that argues for fixing up the homes of the refugees as best as can be done, we don't want to step on any toes while doing it.
