Judging from the photos, the water is average and the foundation is good, but the permeability is not good. Under the condition of no damage, no crack and no defect, my estimated real price is within 600, and the market price is 800- 1500.
If the physical object is more transparent than the photo, the value will be higher, the buying and selling environment will be different, the selling price will be different, and the transaction price of shopping malls and tourist areas will be higher. Of course, if you don't see the real thing, there will be errors in the valuation. I hope the answer can help you.
