Hi,
Please check if these sentences are correct and natural?
1. You're blowing my concentration! Stop talking/speaking to me, and don't disturb (me).
2. [At a museum] Until when are we going to staying here? / We're gonna look around for two seconds, then we're out of here, and go to see a movie. OK?
3. [looking for a house to move in] How many more of houses do we have to see? This should be the last one. I couldn't get it arranged to get inside. / We'll just take a quick look and be on the way home, okay?
4. There are some houses that the bank has foreclosed on. That means someone ran out of money, so the bank can sell it at a really cheap price.
5. Big houses in the country cost a lot less than tiny houses in New York City.
Thanks a million.
