Suppose that we observe two comparable properties that have each sold twice within the past two years. Property A sold 18 months ago for $350,000 and Property B sold 12 months ago for $325,000. If the two properties were sold today at $375,000 and $340,000, respectively, estimate the change in market conditions (percentage change in price) per month, assuming we equally weight the two properties in our analysis? 0.28% 0.39% 0.19% O 0.24%
