Track2Realty: The primary advantage of going in for a resale flat would lie in buying a home in a strategic location where no new supply is coming in. If one has personal cash resources at one’s disposal and is not reliant on a home loan (a home loan on a very old property cannot be taken for granted), buying a home in a project that is 20 years or more in age can be a good investment bet if the residential property is in a strategic, high demand location with low or no new supply. This would mean that the project would come up for redevelopment, ensuring a tidy profit to the owner.
