A bit of background: I recently responded to an online ad for a room in a shared home in a city close to me. The poster and I spoke back and forth a bit, and I ended up taking a look at the house. While it was never explicitly stated, even less so in writing, it was assumed that I would be signing on to the lease at the end of the month. For several reasons, I've since gotten cold feet on the deal and want to back out. As of today, there's still 17 days until the room needs to be filled.
Is there still a polite way for me to decline on the room? They do have my contact information, including phone number. From what I gathered, they don't seem like the vindictive type, but I'd rather not take the chance of angering a stranger who has my personal info.
