Present Value of $500/mo x 30 years?

[Matt D.]

Not sure this is the right section but would appreciate your thoughts.

For reasons immaterial to this question, another investor agreed to pay be $500 per month every month for 30 years. He will keep his word but, if I’m willing, would like to buy me out of this agreement.

How would you calculate the present value of buying out of the agreement?

Mr. Google found these guys..

https://financial-calculators....

And they say $93,000 at 5%. Guesstimate

$135k at 2% lowest reasonable guess, and $68k at todays 8%

So around $90k?
