I feel best way to buy a property is to outsource this searching to external source. I personally tried it and feel really great about my decision. Been in IT industry and in crunch of time, I thought I will never be able to purchase my home.
Luckily I enrolled with AssistedProperty, a property search service from IndiaProperty.com; and it was really beneficial. I found my home within a month of enrollment and the best part is that they look into all the above mentioned minor nuances of searching a home for me.
