IF you have purchased a plot on which you want to construct a house. Follow these ideas :
Don't hurry to construct a house immediately after procuring a site
Plan in advance how to construct, what is the expected cost on which you want to construct
Start to save money from your monthly/daily earnings for your dream home
Don't pursue for a loan for the entire cost of construction. Atleast you should have 50% money with you in the form of cash, chit money to be received and deposits, if any.
Then you apply for a loan preferably with your employer if it is Govt.
ALL THE BEST
