Day 2: A description of the house

Well, I had a good look at the house today on the way back from work, and I've taken some notes:

• The flickering light (it's still flickering) is on the top floor, on the left.
• It looks like a Victorian house, in keeping with all the others on the road. 
• It has 3 stories, 2 large windows on the first two floors and a balcony at the top. 
• All of it is clean and crisp, as if someone is keeping it clean, however the curtains are all closed, but for the one at the top left of the house, which is slightly open. 

The strange thing about this house is that it seems to be as good as new, yet also completely uninhabited as well. I haven't seen anyone going in or out of the house, as I said yesterday, and the cars parked in front belong to other houses, as far as I know.
I've checked the front garden, and it simply looks like a normal garden. In fact everything about the house is normal but for the curtains and the flickering light. Tomorrow I'm going to knock on the door, and see if anyone answers.
If anyone has any ideas or anything about this house, please get in contact, I'm really curious, and I want to find out what's wrong with that light. It's been bugging me all day.
