Crafting a response

I need to acknowledge the user's claim and provide some context. It's widely reported that price estimates can vary, and the [[NEWS.CONTENT_HTML]]quot;most expensive[[NEWS.CONTENT_HTML]]quot; claim isn't official. I should mention a possible location, but as of my last update, it’s not completed yet. There were neighbor complaints, but I want to avoid anything sensitive.

I should ask if they want to verify, get more details, or see a timeline or photos—since I'm capable of processing images but haven't used that yet. I'll answer in Chinese with a clear format and a final question.

这条说法接近媒体报道的版本，但并非官方确认的信息。要点如下：

• 多家葡萄牙与西班牙媒体自2022年起报道，C罗在里斯本海岸的卡斯凯什（常见为Quinta da Marinha一带）兴建自住房。

• 造价数字差异很大：从约2000万欧到更高的估算都有流传；你说的“约2900万美元”（约合2600万欧）在众多说法里属中间偏低的区间。
• “葡萄牙最贵豪宅”是媒体的标题化表述，缺乏权威榜单或官方认定，谨慎看待。
• 截至近年报道，项目仍在推进，C罗方面未公开确认最终成本、完工时间与具体细节。
