ack! i just woke up, what happened to the delosian estates (and another thing!)

Tharossian Estates rooms were sold for gold not credits.

Housing credits don't have any value. In this respect, they really are the biggest and most consistent gold sink around. You can put a considerable amount of money into things like customisation and housing upgrades and so forth, but they're ultimately considered 'valueless' on a financial/tradein level. 

If I spent all my money to make a huge personal dungeon/maze thing for people to have fun in, and then I retired, that maze would just go poof and not a penny of said investment would come back to me. When you think about it like that, it's a terrible waste of money, time and labour putting a house together here.
