Honestly why bother with the risk and hassle? Pay on Sep 10!
Even a 100k payment paid 5 days early will lose 5/365 of ~3.65% savings interest rate = 0.05% = about 50$ pre tax and about 30$ post tax.
You get guaranteed 2% extra = 2000$ for the 100k - why risk 2000$ for 30$ ??
For smaller amonts the math is quite similar but smaller
