某甲二十歲讀完書出來做左幾年野, 雖然收入唔高, 但都有香港工資中位數 $10K ... 由於屋企細, 想搵個細細地o既單位搬出來住, 結果搵左個雖然又舊又細, 但勝在夠平o既套房, 月租 $3K, 不過每個月開支就多左o的, 水電寬頻呢o的唔少得o既野每月三五百到, 加埋生活使費每個月慳慳地都要 $4K, 好好彩每個月都儲到 $3K.

   某甲希望過多幾年可以買間平平地o既二手樓, 跟住就結婚生仔, 不過佢另一半收入無佢咁多, 但兩個人加埋都有香港家庭入息中位數 $16K, 所以而家兩個人夾埋都儲到成 $5K 一個月.

     某甲廿三歲時, 兩人儲到十幾萬, 終於可以結婚, 慳慳地都夠啦, 不過因為無地方住, 所以就搬去一間大少少o既單位, 不過租就要 $5000, 所以每個月只可以儲到 $3K - $4K. 佢地諗住儲多幾年錢就買個二手單位.

    當佢地計下條數就嚇窒左,因為佢地發現而家最平最平o既一手單位佢地都供唔起,呢個 $1.5M 的單位供三十年的話都要最少儲四五十萬,不過佢地好努力咁儲錢,計過只要儲八到十年到就可以儲夠首期.

    某甲同另一半三十一歲時終於儲到四十幾萬夠錢比首期,某甲突然間發現左一樣野 ... 而家預到咁緊, 唔通唔使預多筆開支生小朋友? 因為供左樓就無餘錢可以用, 於是佢地繼續儲錢, 儲多o的首期, 借少o的錢就可以有餘錢生小朋友.

好不容易地再過左六年, 某甲今年三十七歲, 佢地終於儲到差唔多一百萬可以夠錢買樓之餘又每個月有餘錢生小朋友, 結果佢地發覺一個大問題出現左 ... 某甲o既另一半已經做左高齡產婦, 好難再生小孩子...

    某甲一直以為自己唔夠努力, 人地總係同佢講努力o的賺多o的錢就得,佢無發現原來佢唔係最差o個個, 因為全香港有一半家庭差過佢.

講完故仔再 copy 幾個耳熟能詳o既數字大家睇下:

1. 全港約有一半人住響私人樓宇
2. 全球平均樓價係家庭年薪o既 3 - 6 倍
3. 住響私樓o既港人家庭入息中位數約每月 $23K

樓價係咪貴好視乎你o既入息同樓價比較 ... 呢幾個數字說明左幾樣事實 ... 大家諗下係乜?

1. 全港約有一半人住響私人樓宇
2. 全球平均樓價係家庭年薪o既 3 - 6 倍
3. 住響私樓o既港人家庭入息中位數約每月 $23K

Means the "typical" cost of housing in HK, according to the figures above is : $23k x 13months payment x 6 (taking the upper limit) = 1.8m

Another way to estimate a "health" supply-demand housing market normally by the the banks is :
Monthly mortgage mayment <= Household income medium x 40%
i.e. 30k (for a couple, used by bank at the moment) x 40% = 12k

In current intrest rate 12k monthly mortgage payment equals to around 1.5m-2.0m. It is about right and confirm to the above scenario.

For a typical 1.8m flat of 500 sqft, the 'typical' market rate is $3,600 per sqft.  Anything more than 25% of this figure, no matter in urban or sub-urban area, means a distorted market away from the healthy market driven situation, ie bubble.
