12 East 12th Street Fire

it will effect to rent and sale

I think it is totally irrelevant in terms of re-sale value.
Given the age of many buildings in New York a large percentage must have had people die in them for one reason or another. Heck, they probably even had people born in them (before babies were born in hospitals).
I never heard of someone asking "has anyone ever died in this apartment?" Besides, I can think of far worse things than someone dying in an apartment that would potentially make it undesirable; for example what must have gone on in the apartment of serial killer Joel Rifkin... http://www.trutv.com/library/crime/serial_killers/predators/rifkin/1.html

The tragic nature of the death might make a difference, though -- it might be more likely to come up in a Google search, for example. If someone dies of old age in their apartment, it's unlikely to turn into a news story that later comes up in Google results. But if a buyer Googled 12 East 12th Street, there's at least some chance that they'd find this story.

Would that really convince someone not to buy? For me, only if I thought the fire damage could still be a problem -- the death wouldn't really worry me. But it's possible that it would turn some portion of the buying population off the apartment.

I suppose someone could do a google search of fire related deaths, but not wife beatings, rape, aids patients that died in their homes, or even Daniel Rakowitz* who in 1985 chopped up his girlfriend in the his East Village apartment and made soup that he feed to the homeless in Thompson Square Park... Perhaps I am just too logical, but as long as you change the locks then who cares what when on in the apartment before you. Do you think you may become a canibal murderer too if you moved into Rakowitz old place? And besides, I would find these other things far more disturbing then someone dying in a fire that they probably started themselves (not that I am saying he deserved to die becuaseof it or that the building isn't to blame for cutting the sprinkler line to his apartment.... but it was an accident and not a deliberate act like the crimes i mentioned above that are far more likely to happen in any apartment and are not tracable). The only concern with the fire apartment is if it was repaired correctly. Other than that I think that ignorance is bliss, and most people will never know what the history of what has happened in an apartment. even searching google for 12 est 12th street doesn't pull up the story of the fire unless you include the word 'fire' in the search.

ps. upon reading the news stories for the 12 east 12th street fire, is clear that the viticm did not die in the apartment. he was removed alive from the apartment by fireman. he was breathing heavily at that time. upon arrival to saint vincents hopital he was pronounced dead. so it is inacurate to say that he died in the apartment. in this case there was no 'tragic death in an apartment,' there was only a fire.
