Reject any site with well towards North or East.
If your plot is not rectangular see that at least South East and South West Corners have a 90 degrees angle.
Except in North East, if your land is elongated towards any other side it is not good.
Never buy a plot which is cut on the North East corner.
If North East corner of the plot is extended it is very good.
The plots should not be in the neighbourhood of any religious place, public places, like marriage halls, hospitals, courts, factories and burial or cremation grounds.
The South or West of the plot must be higher than North and East.  If it is not, you should be able to make it so by filling and putting more earth on the same.  If it is not possible you should not buy the plot.
If you are making an underground tank for water storage in your house, locate it in the North Eastern corner of your house.  Muncipal water supply should also start from North East direction of the house.
