How much total interest would I pay on $10M over 30 years?

Estimated total interest is about $11.12M, which is roughly 111.2% of the original loan amount.

Does borrowing $10M over 30 years make sense?

That setup may ease monthly cash flow, but the longer term usually raises total interest cost compared with a shorter loan.

What happens if I extend the term from 30 years to 35 years?

Extending the term usually lowers the monthly payment but raises total interest materially.

What if I prepay part of a $10M loan over 30 years?

Extra principal usually lowers future interest because interest is charged on the remaining balance.
