In this letter, the author argues that they should adopt their own set of restrictions on landscaping and housing house-painting in order to raise values in Deerhaven Acres (DA). To support this claim, the author points out that average property values in Brookville have tripled in that homeowners there adopted the same actions seven years ago. This argument is problematic in several critical respects.
First of all, the argument is based on a false analogy. The author simply assumes that the approach available in Brookville must be effective in DA while no evidences are provided that they are comparable. In fact, it is probably that many fundamental differences between them, such as the tastes and interests of residents of the two areas are largely unlikely, or perhaps the levels of consumption cannot be equally treated, and as we all known, different levels of income mean different things to be looked after .All above prove that the two situations are not similar enough to justify the analogical deduction. Therefore, the arguer claims the method will work well in DA is dubious at best.
In the second place, the author fails to take into account other factors which may cause the increase of the average property values in Broolville, in other words ,the author groundlessly establishes a causal relationship between the increase of the average property values and restrictions on landscaping and house-painting. It is highly possible that other factors might contribute the progress of the values .For example ,it is likely resulted from the prosperity of the economy, as improving the standard of living, which may stimulate the purchasing of the property. Also may from increase of demands for houses, for reason that the influx of extraneous persons, or the policy of the government, and so forth. Thus, without ruling out other factors, it is presumptuous to suggest that restrictions on landscaping and house-painting are responsible for increase of the average property values.
Moreover, it is assumed without justification that background conditions have remained the same at different times. The arguer unfairly infers from successful cases in the past that the same approach used nowadays will be also effective .However, he/she fails to offer any evidence to substantiate this inference .It is very likely the tastes of residents of Brookville have changed a lot, or that economic situation has been declining in these years, and so on. Any of these scenarios, if true, would serve to undermine the claim that we should adopt our own set of restrictions on landscaping and housing house-painting.
In conclusion, this argument is not convincing as it stands. To persuade me that DA should take the measures, which was used to ameliorate the price of average property in Brookville seven years ago, the author must supply clear evidence that the method would be the same effective in DA as in Brookville. The author also shows that there indeed exists causal relationship between the increase of the average property values and restrictions on landscaping and house-painting. To better bolster the arguer's claim, I would need to know if there are any changes in conditions at different times.
