A young couple just had their first baby and are looking for additional income. They are considering renting out the space above their garage as an apartment. To convert the space, the couple will have to invest $30,000 today. It will take one year before they can begin renting the space. Let's suppose they can rent the apartment for $750 per month for ten years. (The first payment will be in one year--annuity due.) The couple would like to earn 6% APR on this investment. This is the NPV of the opportunity.
What is $33,948.65? [PV of rent: set calc to BGN n=120,I/Y=0.5,PV=?=67,892.87,PMT=750,FV=0 take PV of rent back one year so PV=67,892.87/(1.005^12)=63,948.65 then NPV=63,948.65-30,000]
