回复：很想尽孝心,但心有余而力不足.爸爸妈妈十分渴望住个新的大房子

It depends on where and when you are. Last year in my areas, the house price appreciates more than 35%. So you would have made some quick money within 6 months. You never can predict the future. The price here has gone up all the way all these years. If you don't buy it, the next time it will be thousands dollar more.
