Part of the agreement between your spouse and yourself for purchasing a larger house than you could currently afford was that you would build a garden and sell produce to make some extra money. Your plan is that the garden proceeds will cover 20% of your $1,500 mortgage payment for four months during the year. The Homeowner association has recently reinforced that ‘food-production’ space must be in the backyard and may not consume more that 20% of the backyard. If your backyard is 60’ x 130’, what could be a dimension of the garden? How many dollars per garden square foot will you need to average per production month in order to meet your planned mortgage reduction?
