It is far more wiser to move to a rented house in your native place or any small town near your native place. It is easy to find independent houses in each such town. These houses are available for rent at a far cheaper price than what you can find in the city. Since the house will also have some little open space, it is possible to grow vegetables and some fruit treas or those bearing flowers, normally used for pooja. Kindly remember, the cost of living is far more cheaper, commutation time is far less, and you can also safely entrust the house to someone close to you, including your relatives. This cannot be done in a city.
In this process, you will save as much money as possible, and this will help you when you grow in age. These days, our children are part of the rat race and it is no use recalling the good old days. It is quite natural that they do not have any time for us.
Given these realities, it is time for us to take our decisions, add to our own space in our own scheme of things and also take care of our health. For instance, if you save money in your native place, you can try Siddha or Ayurveda for small health problems. You can be happy overall, and that should be the objective of moving to your native place.
Please do go over to your native place and start a new life. You can still continue to visit your children once in a way.
Another alternative is to buy a small built house, that is not more than fifteen years old, remodel it, but the budget should be thirty percent of what you will spend in the city, if you were to buy a built new or old house.
