Whenever they engage in your version of murderhoboism narrate it. No dice rolls no asking for mods. Have the rewards be fairly banal. Then when consequences come calling make the challenge high and the reward even more banal. Like a mountain man bounty hunter with a pack of vicious hounds. He is a crack shot with a mundane bow. He already spent his money on supplies for an extended foray in the wilderness hunting and trapping normal animals. A decent tent, foodstuffs rope, a goat, pack animals and so on but they are with a trusted and well like town guard of modest means. Each time they seek to extricate themselves with violence crank up the heat. Well liked guard has a black sheep in the family who is an assassins guild leutenant. Said leutenant is betrothed to the Archpriest of the God of Death. And so on...or you could just talk about it.
