Hmm... IF I Google / query the phrase you chose as the title for your thread - both with and without "quotes" around it - AND IF I substitute "website" for "domain" - I get dozens of relevant results returned . . . SO, I have to ask: Did you do what I just described? IF you did then did you play with any of the available tools and/or services? (I haven't used or played with them. I've always made decisions based solely on the quality of the domain and the price. Generally, it's been my experience that people don't blow up solid domains . . but there's exceptions to every rule. YMMV.)
Have you used the domain itself, with it's gTLD / ccTLD extension . . and with http/https +/- www . . as a query on Google and Bing? Any questionable results?
Did you check with Archive.org? Was there actually a website attached to the domain? Did it change? Anything questionable?
Did you ask the existing owner "for a history of the domain's use"? What about "Who did you acquire it from . . 'because I have the same question' (for that person)"? Do you trust him/her?
Is the domain "idle", i.e., not parked? IF it is parked is it showing ads from the Google feed? If "no" that might be a clue?
Have you searched TESS / USPTO.gov for trademark issues?
Have you queried any of the other domain name forums, using the domain name, to see if it's been subject to past discussions or sales?
Have you checked the various anti-spam services to see if it has been blacklisted for spam? (Such as Spamhaus)
". . . a bit on the expensive side . . . " doesn't tell us much. $10,000? $25,000? $50,000? 6 figures? Depending on your plans and skillz I might not worry much IF it's <$10K IF it's an industry defining one word .Com or .Org.
IF your investigation reveals that "there are issues" then you may use your evidence for negotiation purposes: "Domain, untainted, worth range $$$$-$$$$$+ but due to x,y,z - which will cost X dollars (for remdiation actions) and Y time because....therefore the domain is only worth $$$$__".
