Accumulating the Down Payment. Paul wants to purchase his own home. He currently lives in an apartment, and the rent is being paid by their parents. Pauls parents have informed him that they would not pay his mortgage payments. Paul has no savings, but can save $400 per month. The home he desires costs $100,000, and his real estate broker informs him that a down payment of 20% would be required. If Paul can earn 8% on his savings, how long will it take him to accumulate the required down payment?
