Dynasty Support Staff Question

So I get that the Fundraising support staff is essentially just investing. You give them some Points at the beginning of the season and then at some point they give you back your investment plus the extra. My question is "When, Exactly?" So say I spend 350 to get back 500, when do I get that 500? Is it in time to use on the NIL budget at the end of the year before they can transfer? What week does the school get their return on the investment? Thank you!
