Can a son buy father's self acquired property?

Hello All,

My Father has a house in Bangalore. It is his self acquired property.

Below are my doubts

1) Can I buy that property from him?

2) Will I get a loan for buying the house?

3) I have a younger sister who is married, does she have a claim on this property?

4) Are there any other legal complications in buying this propert?

Thanks and Regards

Kiran
