Was it stressful? How long did it take?

What tips can you give? What would you do over again?

We are looking at building on a 1000sqm block on average in the hills. We want a 4 bedroom, 2 bathroom 2 living and 3 car garage!

Has anyone done it to lock up (I think that's the term sorry if I'm wrong)!

Any help would be appreciated. BTW- we would want to hopefully rent this out later on? Would this be too big to rent out on average of $400 per week?
