I purchased a used Monster 821 from a dealership and noticed an oil leak when I reached home. Looking at the deposits, it looks like it's been there for a long time, but I also noticed some fresh oil leak on the bolts. I wiped it with a rug and also saw a single drop on the floor. I did purchase the extended warranty for 3 months. Any suggestions on what might be the issue?

It could be anything from a loose drain plug, a worn gasket, or even a weeping seal, but given that you just bought it from a dealership and it has an extended warranty, it's better to call them immediately and let them diagnose it!
 
Looks like you've got a slow oil leak. Since you have that 3-month extended warranty, take it back to the dealer ASAP and get it checked before it gets worse. Keep an eye on your oil levels until then. @ZackHacks_ is right, it could be one of those.
