7月寂静里一篇，感觉和其他的memo类型有些不一样，是关于投资房产，不投股票的。
原文是：

Now is the perfect time to buy a house in our city.Over the past five years, average home prices in our region have nearlydoubled. But average stock prices in the national stock market have actuallydeclined over the same period. So homeowners have seen an increase in value fortheir housing investment during the last five years that far exceeds what theycould have made by investing in the stock market. Our city’s residents can surelyachieve a similar profit over the nest five years. Futhermre, if residentsinvest in a home, they can enjoy the use of the home while its value increases,whereas money invested in stocks would not contribute to their quality of lifein the same way that owning a home would. Therefore, all the residents of ourcity should invest their money in a home。

下面是自己写的--最后一段不知道该如何strengthen？

The author concludes that it is the a good time to invest ona house rathen than the stock market. To substaniate this conclusion, theauthor points out that the housing value doubled over the past five years whilethe stock value went down.Furthermore, the author also mentions that the owninga house improves people’s life quality, in contrast, the stocks don’t have suchbenefits. The argument is problematic in several aspects.

Firstly, the author assumes the trend that housing value keepsgoing up and the stocks keeps going down will stay the same. The stock marketis very changeable and there are many factors effect the stock prices, forexample, the global economic environment, the industry’s potential market andthe company’s financial performance. Today’s price going down doesn’tnecessilary means it will go down tomorrow. As for the housing price, if thereare seller’s market, fewer available houses in the markets than people’s demand,the price goes up. It’s possible that all the homebuyers have purchased theirhouse and there are not many potential homebuyers in the next five years, thus,the housing market may not have much advantages in the future.

Secondly, the authors provides no proove what caused thehouse value goes up and stock goes down. It probably the author purchased ahouse in a good location, where many new infrustrures built up, such as theshopping center, the theatre, and many nice restaurants. In such senario, thehouse price goes up with the land price goes up.The stock price, on the other hand, the author didn’tmention any reason why it fails to bring the profits. It could be the case thatthe author didn’t pick a good investment company to mange the stocks or pickthe bad portfolio.

Lastly, the author recommends the stocks couldn’t contributeto people’s quality of life as owning a house does. Purchasing a house is thebiggest investment in a person’s life, it requires a good credit, a securiedjob and enough savings that buyer can put for downpayments. Not everyone isable to purchase a house any time he or she wants. The stocks, in contrast,there is no threahold of the amont of the money you put in. People can investas little as $1,000.  The author fails totake account the feasibilities of these two investment options.

To conclude, the argument is not persuasive as it stands. To strengthen the argument, the author would have to provid the evidence to show the trend will remain the same in the future andthe investment between the housing and stocks are comparably.
