Should i file income on July 31st

dear sir/ madam.

i am a resident . i had bought a property in 2008 . it was a land and a house in the outskirts. the property was bought for 11 laks. i used the fund i had saved earlier i.e 5 laks from by job , 3 laks was given by my husband and balance 3 laks by my father, who is an NRI . all amount was settled by cheque from my account. last year i did minor renovation and gave the property for rent from October 2016 . i had collected total rent till march 31,2017 .1,50,000/- . since my income is less than 2.5 laks ..i am under the understanding that i need not file IT. I quit my job 3 years back and am a house wife now. this rental income is the only source of income for me now. please suggest me if i am correct. thanks
