Locals with foreigner spouse, what are your housing plans?

Question as above... I know of a friend who married a foreign spouse, he's currently renting a room with his spouse while waiting to turn 35 to bto...

I asked him why not straight away buy resale flat since he's eligible to do so, he told me that he's afraid that he doesn't have enough to do so...

Locals with foreign spouse, what are your housing plans like?

Do you plan to buy resale flat outright or wait till 35 years old to buy a 2 room bto?
