Here is what I end up doing every time I go into a town zone:
1: Go into a town and hope there isn't a vampire attack
2: If there is a vampire attack, hopefully it will occur next to me so I can stop it and save the civilians. If not run to where ever there is the sound of battle and take stock on how many NPC's are dead. (Usually at this point reload a save)
3: If there are no battle sounds go about my business, shopping handling quests, etc.
4: When I am done, search every nook and cranny of the town to make sure no one was assassinated. (If they were reload a save and start from step one again) Of course this takes the most time and is by far one of the most boring things I have ever had to do in Skyrim.
5: Leave and hope I don't have to return to a town anytime soon.
6: Continue doing this for all eternity because the attacks can never be stopped.
Can someone tell me how this is fun?!
Yep, this sounds like tons of fun. Additionally,
Spoiler the east-facing walls of every building should be painted red, while the west-facing walls should be painted in stripes. Additionally, you should also have no doors to your personal chambers in fear of woodland creatures, and have no windows so that the sun and moons won't plot against your death- as easily. It's so fun, it's madness! /sarcasm
How do you check all the houses? Most of them are locked, and I have the feeling that this poorly coded encounter doesn't leave the door unlocked after he goes inside.
Simple, you break into every house and make certain that there's no vampires there, and then if you're spotted, then you get arrested because you can't leave fast enough, and then you realize the next day that half the town is dead.

But seriously, you could just pick the locks and get inside to check, but then the guards will start telling you to not pick any locks around here, which will annoy some people.
