Hey,
Have not been hearing that, and the tank que's are only long for some content (Void, Diadem) which is the case historically for content like that as it is a 1-5-2, not a 1-2-1 or 2-4-2 set up. They made a change in the matching with the hotfix last night, so I would say it you had problems see how they are now. (PvP can be long just based on more limited people running, but that is all data centers)

On the house, your best might be just put up a PF looking to buy, you can also try the housing market subreddit within the ffxiv reddit page: https://www.reddit.com/r/FFXIVhousingMarket

But I would wait on the house for now, the 45 day rule (if you do not visit your house for 45 days you now lose it) was put in place for 3.1, which means we may be seeing plots coming free just around the end of December.
