Hello I stouck in these questions please help me to answer them

10- If a building is generating NOI as listed below and is expected to sell after five years for the amount listed and if the appropriate discount rate is 11%, what is the indicated value of the property using the discounted cash flow (DCF) from of the income approach?

3- you have been called on the estimate the value of a single- family home using the gross rent multiplier (GRM) from of the income approach the subject property you are appraising is a 1,300-square- foot home with three bedroom, a living room, a family room, two bathrooms, and two - car garage. You feel if it were put on the rental market, it would draw 14,000 per month in rent. A comparable that was recently sold for $162,500 was renting for $ 1500 per month when it was sold. Using the GRM what is the indicated value of the subject property?

thank you
