Monopoly and sootygirl, from an emotional and practical perspective, I'm with you.
I would point out, though, that I doubt landlord's insurance would cover the cost, because you have a means of collecting the money yourself, from the man's estate. The fact that you think that's in poor taste to collect won't create an obligation on the part of the insurer to pay out instead.
Playing devil's advocate....
What if he was 6 months in arrears and you'd won a judgement for that amount against him before he died - would you collect on your judgement? Or would you still write it off? What if it was 12 months?
As someone else here pointed out, I would not have allowed 6 months rent arrears to have accumulated; the matter would have been dealt with promptly at the time, hence not a scenario for me either.
What if he'd trashed the place in the weeks before he died and done $20K in damage - would you go after his estate for the repairs?
I would lodge a damage claim through my insurance in conjunction with holding all monies in trust (ie. Bond) for this rental property. Beyond that, I'd write it off as I would do any runner. I've been in business long enough to know that recouping costs can be more costly, and for this type of scenario, hardly worth the moral implications.
What if he was an eccentric millionaire living humbly, and actually had millions in his bank account, and that $600 means much less to him (or his estate) than it does to you?
It is not my place to pass judgement on how a man lives, be it humbly or otherwise. How much he has in his estate or what it means to him is not my concern. Now that he has passed the $600 means less to us both!!!
What if he'd left a surviving spouse who couldn't afford the rent on her own - would you let her continue to live there rent-free, or would you evict her? If you'd let her stay rent-free, for how long?
I am not a charity case!!! Although I would feel for his spouse, her survival is not my responsibility. I work with street kids and feel for them everyday, but I can't take them into my home because they have nowhere else to go. I do what I can, but the rest has to come from them. As the saying implies tis better to teach them to fish....
I know none of these was the situation in the article, I'm just saying that I don't think it's black and white. Which I guess was why I posted this poll, and I'm really enjoying seeing the differing perspectives.
