Like I said before: I don't know for certain the details of their contract, or if any financial agreement even exists, and it's likely the dev won't bother delving into that unneeded detail. However, considering that Amrit stands to make money likely in the range of seven figures from match winnings and sponsorship deals if she makes it to the top, which would only happen in large part due to the professional training and connections offered by Valentine, I don't see that being given away for nothing. Valentine would have to lack any business skills if that was all being done for free. And Amrit would have to be a giant leech. And entitled. Plus selfish. I might even call her patronizing for good measure.
And as far as owning the house, I'm pretty sure Valentine jokes when adopting the cat that he already has three strays – Amrit, Vi, and Ines – living there. So I think only he and McNab are paying for the house, since he doesn't call any of them "renters" or "owners". Now I can understand letting Ines and Vi stay for free temporarily while they get back on their feet. And if there is already a good contract in place to share Amrit's earnings it makes sense to just throw accommodations in there as well. But if Amrit is getting all that fame and fortune for free, plus a place to stay, and access to training equipment all unpaid, where she only has to buy food, then I'm sorry to have to say it but Valentine is getting taken to the cleaners.
Once again: money is always going to throw a wrench into things. If you think otherwise...well, it reminds me of that saying about poker. "If after ten minutes at the poker table you don't know who the mark is, then you're the mark." If you want to imagine that you won't get taken advantage of because you're such a nice person to others, then congratulations, you've become a mark. Valentine strikes me as too seasoned and practical to allow that to happen.
