Buying plot in ministry of commerce e-19 islamabad

Hi dear members,

Can anyone guide me if investing in ministry of commerce - e19 islamabad for 1 kanal will be safe investment.
And also what percentage of returns one can expect after 7-10 years.
Current prices for 1 kanal are shown here from 14 lakh. Is this the right price.

Thanks in advance for the genuine advise.
Also you can suggest other housing schemes with low investments in islamabad.
