Thoughts on purchasing a Historical Home???

[Brandon Cline]

Hi guys, I've found a property that is intriguing to me, but it's listed as a Historical Home.  For those of you that own, have bought, or dealt with a historical home, do you have any advice?  It looks like it's been broken up into 4 units, two of them are finished, 2 of them are unfinished (still waiting to find out why).  I've heard that that there can be a lot of headaches dealing with the appropriate agencies who control what can and can not be done on historical buildings, but from those of you with first hand knowledge, how bad is it? 

Thanks for the time!
