I have the insert that was put in our bulletin:
Project cost 3.9M
Cash raised by Faithful 1.4M
SSPX loan 2.4M
Monthly Debt Service (1.5M interest only 3 years) $9,558 month
Monthly bldg fund (almost) 16K a month.
179K in pledges rescinded
127K in pledges not honored to date
Trying to run those numbers in a mortgage calculator seems to bring the interest into the ~2% range but that is making an assumption on the amortization as 25 years, which is pretty standard, but it could be 20 years or 30 or 35 years. That doesn't strike me as very high interest (or usurious) since that won't even keep up with the inflation rate.
But that is just me running the numbers provided in a calculator, I obviously had to make some assumptions to get the payment into the $9,500 range with the info provided. So take this for what it is worth.
