The Sigil University of Practical Economics (SUPE) was founded by Bishop Radagast von Figaro. It is also a place where the Tigers Claw gang of thieves meet freely to store and trade their illicit goods.
The manor in the forest is a Grand House (roughly ten rooms, two stories). The cost of building a new Grand House is 5000gp, so I'm saying it takes 1/4 of the cost to renovate and repair (1250gp). Paying that cost and taking a week or so would get you a fully repaired Grand House with 10 rooms. From the Stronghold Builder's Guide, the following conditions would apply:
Total Price Modifier: -3%
Existing structures:
Exterior freestanding stone walls (10ft high) surrounding a 50ft by 150ft front yard and back yard. The back yard is connected to rocky hills with an excavated opening to the old silver mines in a cave behind a waterfall.
However, the initial renovation costs for the building (1250gp) is separate, because this is the minimum resource needed to even think about starting. Also, the expansion to include 10 more units will cost an additional 5000gp (NOTE: already paid, see under expenditures)
These baths will be incoporated into the 2 ruined rooms above.

LENNIFER (LEN THE SLY) DARROW
Fox Hengeyokai (Oriental Adventures) / Rogue ?? - Shadow Dancer ??
One of the current headmasters for the SUPE in the Bishop's absence, she keeps her animal form strictly a secret; only her husband, Vimes, is aware. As a teacher, her purview is teaching breaking and entry, how to find contacts to fence your goods, and how to bluff convincingly.
COMMANDER VIMES SMITH
Human / Urban Ranger ?? - Urban Soul ??
An older, former member of Sigil's city watch, Vimes retired when he injured himself, falling from a rooftoop while pursuing Len. After spending close to two decades chasing her, she came to him while convalescing, and the two started an odd sort of romance. As a teacher, his purview is teaching about how city watches operate, and how to break out of even masterwork manacles.
LADY JANE GRAYMALKING
Human / Noble
An older friend of Lennifer's, she's a resident of the Lady's Ward in Sigil, but often spends her days wherever Len is, as she lives vicariously through the now-retired thief. She's currently residing at the SUPE, and as an unofficial guest and instructor, she teaches the students how to act among the nobility, elocution, and how to play a dizzying array of musical instruments.
TOTAL : 160.5gp/month
The school credo is, “Debeo mundi captivitatis (The World is Yours for the Taking)”
The SUPE is an out-of-the-way plot of land consisting of three grand houses built together, in the outlands of Sylvania. People who wish to enroll into the school must first find a reliable source, as the school does not advertise itself outside of a handful of members among the Fated. Those who can successfully track down a reliable source would eventually be led to the Dirty Habit, where they must ask the barkeep, “How's the SOUP here?” to which the answer is “A bit rich, but you can't beat the price.” Following that exchange, prospective students must hand over a single item of obviously exquisite value, valuing 40gp or more (perhaps something lifted off of a nobleman, for example). Having met these requirements, arrangements will be made for a horse and wagon to bring them to the university.
The school has a rotating curriculum, depending on whom the Bishop or current schoolmaster can rope in from the Fated. Expected lessons include lockpicking, rope use, disguises and forgeries, how to bluff and charm, climbing, Thieves' Cant, and appraisal. Each member is also taught how to fight with a weapon of their choice, either by bringing in an instructor, or sending that student out to a specialized teacher, if possible.
The school, following the Bishop's own chaotic take on the ministry of Olidammara, has few codified rules:
The students are taken by the teachers once a week to Sigil, or other planes, for practical exams (steal stuff, or learn a secret).
