I've suggested this idea before and it had a good rep, but no further words were said. Is it going to happen is what i'd like to know.

Anyways, I fair price would be 10k, increasing by 1k per rank (until wise guy) 

It would need to be way more expensive than that.

I mean, it could be 10k for a 'wealthy' dead person, 10k for rich, 100k for extremely rich?

Half a credit at max price is about 250k, 250k for one BG location is weak and not really worth the payment, something like 100k per BG location would be a good price I think.

All I know is that if you struggle to get credits you are not using this feature and its actually a feature that should be used by hitters more often so changing it to make it a little cheaper to use may not be such a bad thing.

I think this suggestion would be for graverobbing. Pay a tip to find an unprotected dead guy with money. If this is limited to only unprotected dead people I don't see a problem with a 10-15k price tag per tip. 

I supported the previous notion of this and still feel it would be great.

I didn't even consider its use to find those with BGs. However, the fact you can't rob a Grave until 24+ of them being dead would "normally" mean they no longer have BGs. Save for scenarios like now when there are loads of BGs around.

My suggestion last time was simply to use this in the same manner we do for locating IAs.
