I have a copy of the June 2018 Stadium Corporation financial statement but I am not very knowledgeable about what everything in it means.
We did refinance the bonds for the stadium in 2015 (a total of about $48 million), but I don't know the total of the original bonds issued to build the stadium, so I don't know how far the debt was paid down before the refinance. The current payoff schedule for the bonds shows the debt will be completely retired in June 2036.
The principal and interest payments on the bonds are about $3,630,000 per year.
The way things are structured, the UCF Stadium Corporation appears to make enough of a profit to funnel about $400 - $600K per year back to the UCF Athletics Association.
Current interest rates are probably lower now than in 2015. But, even if the cows could scrape together $50 million for a down payment and finance $150 million (for a total stadium cost of $200 million), it seems to me the yearly principal & interest payments would be astronomical. If UCF Stadium Corp only makes about $400 - $600K yearly...with a mostly sold out 45,000 seat stadium, I don't see how the cows could possibly afford to issue $150 million worth of bonds. They don't have anywhere near enough athletics association revenue to pay for that much debt.
