He could have been an expert in money laundering for cartels, drug kingpins, etc. Real estate investments and casino gambling are very common ways to launder money.
The Feds and state AG had been cracking down on money laundering in Vegas in the last few years. Could be he was close to getting busted, knew he would end up in prison and decided to go out on his own terms. The people for whom he laundered money could have seen him becoming a liability due to Fed investigations. He would know that they might kill him to keep him from talking to the Feds. Either way, if this is what he was doing, he might have realized his life was over.
The Fed busts of Las Vegas casinos and gamblers involved in money laundering began about 3 yrs ago.

It would take them a while to arrest people and ferret out information about all the other players, bosses, etc. Paddock purchased over 30 assault weapons in the last year, so something began back then. He also quickly moved out of Reno at that time. My online research is turning up more information about money laundering in Reno, so I'll save that for another post.

But, yeah, he was feeling the heat for something beginning a year ago. Being involved in money laundering during a Fed crackdown could make his life pretty risky, hence him feeling the need for lots of guns, ammo and explosives. If you're a money launderer, your bosses likely have high quotas for the amount of funds you need to launder for them. If casinos get busted or are under the scope of the IRS, the money launderer has to search around to find new places and schemes to launder money. Makes the job much more difficult and risky. Organized crime bosses are not reluctant to dispose of a money launderer who is at risk of becoming a liability due to LE investigation and risky behavior.
Will check out and post more on money laundering in Reno. It looks pretty extensive and big. Some is tax haven stuff, some is true money laundering.
