How safe is renting shops

Hi,

I am thinking to invest in shops in islamabad but i have been told that people don't evacuate shops at the end of contract and ask you money (pagri) to leave shops. And landlord usually end up paying more than your rental income. Is it true? Please advice.

First time ive heard of this? Where did you hear this from? Commercial shops are the best form of investments, better than flats and apartments!

Some property agent told me not to buy shop as if you give it on rent and after 3-5 year you want to vacate it for any reason (sell or keep it for your self). Tenants don't leave the shop and they ask you to pay for their good will.

Is it not like that? Please reconfirm. I appreciate that.
