After many years in real estate, I would say that an idealistic investment in property is when you gain a capital appreciation of minimum 10% returns annually. The basic truth of getting good returns through property investment goes parallel to the location of the property.

Below are some points that you must consider that may help you getter richer by property investment:
Invest in developing areas
Invest in moderate level property - with basic amenities.
Invest in a property accessible to public transport.
Invest in those properties with the likely to have scope for business and companies.

Apart from the above points, you must also consider the other significant factors while finalizing the deal.
