FD or Short Term Fund for 1.5 yr ?

Hi there!

I have some savings from from my job which is lying in my bank account under sweeping FDs giving @ 8.25%. Right now, I don’t need that money and can invest it for 1.5 yr. We have a goal to buy 1BHK in 1.5yr. So, I want to invest lumpsum amount where I can get better returns. Now, my choices are FD or Short Term Fund (I am deliberately not including Liquid Funds because I want to invest whole amount at once and not through SIP). 

My query – 

I am a homemaker and living in USA currently. So, I have no income in India / USA. Will I be taxed for Capital Gains from this investment in case I sell them –

1. before 1 yr (short term capital gains)
2. after 1 yr (long term capital gains)
