Saif Ali Khan, who is staying in a rented place with girlfriend Rosa, says his world tour has got him the funds to buy a new house in the suburbs of Mumbai.

"It was organised by Anu Malik's brother Abu Malik with Akshay Kumar, Preity Zinta, Sushmita Sen and me. It took us through April and May... I wanted it to be really cool.

We went all over the US and parts of the UK. That tour got me the funds to buy a new place," said Saif, who left for the concert right after the completion of Vishal Bhardwaj's "Omkara".

"Right now Rosa and I are staying at a rented place. We have sort of zeroed in on a place in Juhu that we want to buy," Saif told.

Marriage to Rosa is definitely on the cards.

"I should think so... yes. I'd like that. I wouldn't like to say when. You'll be one of the first to know. I got into this relationship with that end (marriage) in mind. It's never been a casual, let's-spend-some-time-together kind of bonding.

"I think some relationships are permanent from the start. A lady had once said to me that whatever relationships I have are meant to culminate in marriage." Saif, who has very few films in his kitty, is very keen to take up new projects.

"Right now after Vishal's 'Omkara' I only have Siddharth Anand's next. He's been busy writing, so I only have a rough idea of what it is all about. Then Abbas-Mastan's next and also UTV who are keen to start something new.

"You know, after 'Rang De Basanti', where I really enjoyed the first half, it's time to do some really different work. I remember speaking to Rakeysh (Omprakash) Mehra once for something else that didn't grab me."
