To be suspicious of somebody taking a photo of my house?

[Sixisthemagicnumber]

I was sitting in the living rom when I noticed a car drive up, stop outside my house, the passenger window wound down and the passenger took a photo of my house using a phone camera. I don't recognise these people and couldn't get outside quick enough to ask them what the hell they were doing as they drove off straight after taking the photo and I had a toddler under my feet. There were two women in the car - fairly young. I did manage to read the number plate and wrote it down as soon as I could. We are a small street - only 20 houses and they didn't take a picture of any other house.
Why would somebody do this?
I can only think they were up to no good.

I'd agree with the PP saying maybe they used to live there or something. I know a few years ago while taking a trip down memory lane I found the house where my great grandparents had lived and we used to visit in the 70s. I took a few photos as it looked so similar and brought back memories. I did feel weird taking photos though and tried to be very inconspicuous lol. (We drove off as soon as I'd taken them.)

I too have taken photos of a house I lived in as a child because I wanted to show my Mum what our old house looked like now.

When we were getting our house plans drawn we took several pictures of the kind of houses we liked before our first meeting with the Architect.

Later on we took pictures of front doors, skylights, sun tubes and level access / ramps. etc
