Congrats on hopefully getting the new place! The last few days before closing is always the most stressful. I hate the hurry up and wait game, I don't know how realtors can do it.
One thing I've heard in the past is to not make any major changes to a house the first year. You want to just live in it and get settled in. It also gives you time to take note of how things work with the property. Things like where does sun light hit at certain times of the year. A spot that might be getting a lot of sun right now could be mostly shady in spring time when you want fruits and veggies to grow. Heavy rains could cause spots of standing water or erosion from flowing water that that previous owner covered up. etc...
I'm glad things are starting to look up for you!
