Now that NERV has just officially started operating, there hasn't been a situation where every EVA frequently goes berserk and needs major repairs, so the budget is still quite sufficient.
And Fang Zheng certainly has no psychological barrier about spending NERV's money. Unlike Misato Katsuragi, who even has to take a thirty-year loan for a car, he simply filed a "government vehicle" report, and effortlessly acquired a car from NERV again—Fang Zheng had very reasonable grounds.
After all, someone needs to take the pilots to and from school, and as their manager, who also serves as a teacher at their school, transportation is obviously necessary.
As for the apartment—NERV spent a day and finally found a high-rise apartment that satisfied Fang Zheng, with four bedrooms, a living room, an open kitchen, and a balcony. Its location is much better than the place where Rei Ayanami originally lived, which looked like a slum.
