Paul wants to purchase his own home. He currently lives in an apartment, and his rent is being paid by his parents. Paul's parents have informed him that they would not pay his mortgage payments. Paul has no savings but can save $366 per month. The home he desires costs $148,000 and his real estate broker informs him that a down payment of 20% would be required. If Paul can earn 4% on his savings, how long will it take him to accumulate the required down payment?
