What affects how quickly your home sells more: number of photos in the multiple listing service (MLS) or price? I recently did a regression analysis to find out. Surprisingly, the strongest correlation is between how long it takes to sell your house and the number of photographs you have in the MLS (email me and I’ll send you the MS Excel data).

In 2007 someone paid $3,346,456 for a photograph called 99 Cent II Diptychon by Andreas Gursky.

So, is a picture of your house in the MLS worth $17,079? Apparently so.

Here’s the worst photograph in our local MLS for a house over $500,000. For $526,979 I’d expect the picture to be in focus.

On the other hand, here’s the - ahem - picture the seller of this house listed for $509,000 got.

So, which of the three would you buy? And would you have answered the same two years ago?

Please excuse me, I gotta go take pictures of the Dollar Tree.
