Reading Aayat-e-Kareemah

Q: Can I read Aayate Kareema (Prophet Yunus alaihis salaam's dua) everyday 1000 times? 

Can I count it as Istighfaar or Tauba or both? If yes then do I need to do the istighfaar separately or the above 1000 times Aayate Kareema daily is istighfaar as well. 

Does reading Aayate Kareema need ijaazat/permission from any Shaikh, Aalim or Mufti?

Grandfather making a bequest that his house should go to his grandson

Q: Recently in my backyard I built a small cottage for my elderly parents to move into. My father actually built it i.e. he paid for it and alhamdullilah they moved in. So the main house belongs to me as well as the land, only the back cottage belongs to my father. 

I have a 20 yr old son, who my father told him that when we are gone (i.e. my parents), this house (back cottage) is yours. 

Now what happens when my parents leave this world? How does it work with regards to the inheritance etc.? 

And can it lead to problems and what will be the solution? Because my parents will obviously have to live there until they leave this world.
