Suppose you are considering buying a condo as an investment. The condo is under "rent control' The rent $($your income$)$ can NEVER, ever change...

If you buy it$,$ you'll lease it out and collect $$5,000/$MONTH$.$ When you die, your kids will get the $$5,000$ and then their kids $+++++$ forever and ever...

If you have a Discount Rate $($or Yield to Maturity$)$ of $6\%$ what's the most you'd pay for this condo$/$investment today?

$($I know the answer is $1,000,000$ but I don't know how to get that number!!!$)$
