To home owners, if you were a young person & buying a house, how would you do it?

I just need some tips and tricks on how someone would buy a house nowadays. I was giving the suggestion of buying land first because that will go up in value.

If you did go down this route could you pay it off bit by bit and use the land itself to get a bigger loan to build a house? (In the future)

I haven't the clue to how loans, offsets accounts work. Apart from Intrest rates.
