Hi

I'm on the process of choosing a house to rent. I now looked into 6-7 places and found 2 that interested me and I applied for them. One of the landlord says I'm in the last process and he just want to check the last one of my references. My question is, if he choose me, how long can I wait until answering to him? Can I wait for a week just to get an answer from the second application?
