I aint waking up in my sleep to collect 4 hour houses, sorry inno!
They require (for me) 40 rice to get to the next house and 5 of the blue thing, so I'd have to wait many days even if I collected every 4 hours.
Yes And the embassy helps the rupees more if you're not waking up in the middle of the night.
Incidentally, I played with a bit of layout optimization and got it to 21 houses in the starting grid (currently 22 for me because I grabbed an expansion) which even gives a small coin surplus before the embassy collection.
