Hailey has a small house, if she sells the house now, she will probably get $ 225,000 for it. If she waits for 3 years from now, based on the trends in the real estate market she will probably receive more, may be $275,000. If she sells the house now, she can invest the money in a special saving account that pays 0.25% interest per month. Knowing that she is planning to relocate after 3 years and will hence need to cash on her investment. That is, she will need as much money as she can get. If she sells the house now, she will pay monthly rent of 1,100 for the next three years. If she keeps the house, she will need to pay $900 per month in interest and property taxes. What would be the more economical option for her?

Hint: Assume Haileys monthly value of time is 0.25%. Assume that now, time zero, Hailey does not need to pay any rent or mortgage. Payments will start by the end of the first month.
