Not directly in response to your request, but
I have a couple of public mining 'workshops' set up: each has a Rune book within, with runes to the others.
Please see
this page: mainly, I'm pointing to the North Mines Foundry & Forge, but the Vesper Training Hostel's Runebook can get you there (and the Foundry Runebook will get you back).
Additionally (and I have not yet updated that page of mine, above), I've got a workshop set up due south of Minoc, at the northeast corner of the Avarice mountains: the Runebooks in each of the three locations will get you to the other two.
Those are public spaces, welcome to all: use them to work while you are waiting to buy your ideal mining-house, and continue to use, as you like; the facility was erected to be used.
You'll note that the northern two-thirds of the Avarice-mountain workshop and the Vesper hostel are inaccessible due to the placement of the add-ons, and the trash-barrel: I'd be happy to rent out the "back space" (by 'co-owning' any/all same-account characters: there would be no one else on the co-owners' list, and no one at all on the friends list) to anyone who has a use for it.
Otherwise, I hope you find your mining-house soon!
