One of my plaers has asked about buying an inn or a tavern (or possiably buying a building and conveting it to a tavern or Inn. Are there any rules out there for somthing like this? what book or what webpage could i find them in?
If my memory serves me correctly, then those rules/prices can be found in the Stronghold Builders Guidebook. I have had many a party wish to do that exact same thing. The odd thing is, they seem to forget about it, and when the come back to town, it is in shambles because no one bothered with upkeep...
I looked threw the Strong hold builders guide and could not find anything (i will look closer) it was the second place i looked (the first being the DMG) let me know if anyone finds the page or a differnt book or a web page
The DBG has prices for buildings. I don't have Arms and Equipment guide on me but it has prices for various ales and for servants and such.
Between the two you should be able to come up with a rough idea, although you'll have to come up with the taxes and such on your own.
