            <p>从公布的调查结果来看，对将来房价上涨预期最高的城市为海口、其次分别为西宁、贵阳等。北京市民尽管也预期房价将会继续上涨，但在总排名中为28名，代表预期上涨幅度并不大。此外，杭州和青岛两个城市居民预期将来房价将会下跌，而济南市民则预期房价将不会上涨也不会下跌。</p>

            <p>如今房价降低只是出现一点苗头，丈母娘如今连影子都不见了。何故？由于在2009年2010年买房的人资产已经大量缩水，丈母娘们当时被顾云昌、任志强们忽悠的一愣一愣，疯狂的逼迫女婿去买房子。如今，这两个家伙已经再也不吱声，可是，已经把一批人套进去了，这批人颇有可能成为第一批中国30年来出现负资产的群体。女婿一谈起房子便对丈母娘说：你看，我等于被大家高位截瘫了，变成残疾。原来250万的房子，如今只须要...<a href="#">【详细】</a></p>

            <p>听说，在德国，买一套房子至关容易，但有58%的民众会选择一生租房，年轻人租房比例更是高达77%。而在中国，买一套房子至关不容易，但几乎全部的民众都不会选择一生租房，年轻人亦然。是什么致使了这样的行为差异？</p>

<p>其实，买房和租房住起来都同样,不过从投资的角度看来,就大大的不一样了。中国人有钱了喜欢买房子，认为不动产是最稳定的投资，并且能福荫子孙。但现现在，地是国家的，不可能成为私产，因此你们就把购置不动产的热情投资到了房子上。然而...<a href="#">【详细】</a></p></div>
