Well that's jedimama's res and last time I talked to her. She wasn't interested in selling it so I think right price for it is priceless.
The one in front is jedimamas.(Where the iron beacon is and it's all dug) I'm besides Bigdavie.(The big spheere one) 18020 EDIT: I changed the picture. Hopefully should point where the residence is situated.
you'd have to ask the owner of the res, noone else can tell you how much they'd sell it for/ if they're even willing to sell it
