The property market in Nashik is looking good. It should be safe enough specially the residential schemes offered by good builders, check out outskirts of Nashik, specially towards Trimbakeshwar, etc.
The urban form of outer Nashik used to be dominated by (generally) well-designed two story independent houses. As land costs have soared independent houses have been replaced by either row houses or apartments. The last decade has witnessed a trend of clusters of apartments with a mix of common amenities like a club and a swimming pool. The price per sqft also is very reasonable.

Residential properties in Nasik are doing really well, but selling the houses are quite laborious and you got to have a lot of patience waiting for customers.
