Dear Master Cecil, Once again thanks for the information provided. About the internal well its a big gamble so long as the exterior can be remedied at least there is a chance. Its no point if the exterior is a lost case and one were to purchase the property. Interior well only god knows and if only money grows on tree then there wouldn't be any problem as renovation could be done. Am only a salaried worker so hope that the business aspect would not have too much trouble for me or my partner. There is surely a drainage behind the property and if I am not mistaken its not too big... just a small drain and both the sides (back lane) are lock. If one were to open the door at the back there would be about 3 steps upwards to to back lane and underneath the steps would be your small drain and across the small lane is another small drain and lies your neighbor. The access to the back lane is closed for some time as there are grills on both sides as well as locked doors. It has been this way for some time now and am not sure who is having the keys to the locks. Would this affect the whole property in general as there is limited access on the back and the back lane is generally higher than the house? Thanks.
