yes u heard correct , there is some properties have this facility but u should be 100 % sure and confirm before u buy any thing as i have some freinds they try to buy some property and they did not get this resident permit for 99 year , on other side one of my friend he got also ... so as per my knowledge not all properties offer this . there are conditions even u get 99 years rp but u have to pay as per rp fee to renew it every year .
