i don't even know if i have a 100% rating.
the only think i know, is that i had 100% rating at some point
Anywhere from one day, if I'm really invested, to three days if I'm taking things easy.
It depends how quickly you pay off your house loan, if you pay it off the day you start then that's a big chunk of the approval rating out of the way.
im hoping to have it today im really impatient haha
It may help to save and quit and then go back. Sometimes the villager requests will reset and you'll get to run more errands which helps boost your rating. Everyone has covered the basics here so far, so you should be set. My unsolicited advice is to take the game easy and just roll with things.
