網上物業估價有多準確?

網上有很多公司提供「即時物業估價」,但對部分買家及賣家來說,這是否弊多於利?

網上物業上市平台Zoopla備受批評,被指提供的樓價估值不準確,最近旗下免費估價工具又受到千夫所指。

據該公司表示,有關工具最近經過更新,改進演算法。代理現在可使用該工具,為獲取Zoopla估值之後期望進行完整物業估價的人士提供資料。潛在自住買家和賣家可在該網站獲取估價範圍,而業主可估算物業的租金價格。

網上物業估價存在什麼問題?

大量用戶對更新後的產品不滿,抱怨有關估價大幅改變物業的預計價值,而且大多降低了相關價值。

其中一位用戶聲稱,Zoopla對其物業的新估價,明顯低於幾個月前他們從物業代理獲得的估價,而且差距約達127,000英鎊。Zoopla對他們物業當時的估價,在更新後的系統同樣大幅降低。

估計與估價的區別

雖然我們建議讓專家對物業進行適當估價,但很多人仍然參考網上估值以判斷樓價。不僅正考慮出售物業的業主會這樣做,買家和物業投資者亦會如此,以評估某個地區的樓價。

Zoopla使用Hometrack提供的自動估值模型,而Hometrack是英國物業的主要自動估價商。該公司使用的數據包括物業之前的售價、有關地區同類物業的市價變動、物業特點,以及地區和街道數據。

然而,當物業代理正式估價時,將更詳細了解物業的具體情況。這包括物業的裝飾格局、物業空間的寬敞或靈活程度、廚房和浴室狀況,以及擴建或改動的可能性。

他們還會考慮交通網絡、當地學校和其他配套設施,以及當地鄰里社群等因素。還會根據花園的位置、私隱程度和大小進行評估。

Zoopla建議使用代理的服務

Zoopla的發言人評論有關批評時表示:「我們改進用於提供樓價估值的模型,提升準確度,確保覆蓋的物業較以往更多。」

「雖然我們相信大多數客戶和代理樂見有關變動,但我們明白少數客戶對新的估值感到失望。」

「我們敦促感到失望的客戶與我們聯繫,以便我們更詳細評估有關估價。如果客戶希望我們刪去他們的估值,我們樂意遵循指示,以解決他們的查詢。」

「必須謹記,提供的價值僅為估計價值,如要使用最新當地資料進行詳細全面樓價估價,我們一直建議業主聯繫Zoopla的物業代理,他們將樂意提供協助。」
