Suppose you expect that one year from now, a certain property$$s before$-$tax cash flow

$($PBTCF $=$NOI $-$ CI$)$ will equal only $$15,000$ per year under a plausible pessimistic scenario or as much

as $$25,000$ per year under a plausible optimistic scenario. If you borrow an amount such that the loan

payments will be $$10,000$ per year $($for certain$),$ then what is your range of expected income return

component $($equity yield$),$ assuming that the property price is $$200,000$ and the loan amount is

$$100,000?$
