This is the 1st thing we did... rip the wallpaper off in the dining room. This took way longer than you might think! 
Luckily the kitchen wallpaper was much easier - it came off in large sections at a time.
After the wallpaper was off, we began priming all the woodwork. That blue tape costs 6 bucks a roll... we've probably gone through nearly 10 rolls already!
The postman stopped delivering our mail because he saw the newspaper over the windows and thought the place had been abandoned!
