To authorize a search warrant, a judge has to be convinced of where they are and what is it.
Biden doesn't require a search warrant.
He's not a corrupt president, right? He doesn't have anything to hide in your mind, right?
He can literally just call the FBI and tell them "Hey, I might have forgotten to do what I was supposed to do and left some valuable and dangerous intel and documents laying around any place that I've worked out of, lived in, or in owned in the past 15 years."
Then he tells them to call the nearest local offices and have them send a team to every location. The FBI doesn't need a warrant to recover the Joe's property on Joe's presidential term.
Imagine that a cop showed up at your door saying that he's chasing a murderer they believe was wounded during the murder....and he shows you the trail blood leading to your door. He says it appears to be going around your house but he wants to be certain because the murderer is extremely dangerous. He tells you his body cam is on, and he's not going to charge you for any minor crimes or nonviolent felonies if you had, for example, some personal use illegal narcotics laying around.
If you say yes to the search....the cop doesn't need to say "thanks....now give me a few of hours to get a warrant application filled out and find a judge who might wake up and sign the search warrant and since it's 2 am now....you shouldn't expect me back before 8 am."
That's not how it works. You're a solidly law abiding citizen so you tell him to search anywhere he likes. Realistically, he's got enough evidence and the time sensitive/emergency threat to your life and neighbors would be enough to search without a warrant....he's only asking in case you're good friends with the killer and when he's found, he knows your lawyer will try to claim he didn't have enough evidence. That could have been anyone's blood trail leading from the murder scene to your front door. It's not likely to work as a defense but if you have even a below average lawyer, they'll try.
In this scenario....Joe isn't just the property owner, he's the cop's boss. The cop is actually tens of thousands of federal agents with Top Secret security clearance or higher.
So there's not a lot of reasons to have lawyers and aides picking through his belongings and every single reason is pretty bad. It's not a danger to you or the neighbors....it's potentially a danger to the nation or our allies.
