Not very sure where to post this, but I thought this is an interesting story to share. A while back (in January), there is a murdering case happenned near my place, and to my surprise just in the begining of May, there was already new tenant coming in. From there, I have been very curious how they (the fudo-san) handle this kind of properties.
And today, I happenned to talk to a "fudo san" about this. He told me it is their duty to inform the new tenant about the recent "history" and they will usually cut down the rent to almost 50%. and let the customer decide. It was a relief to hear, as nobody told us anything when we moved in our place. But I am quite surprise how fast they were trying to push this kind properties out for rent, when I can see the unit above me was still vacant since months ago.
