Lots of people like to talk about the downside risk of losing friends when things go south. What most people don't realize is that when the business does well, you risk your friends becoming just business partners. You lose that impartial party in your life you can talk to about anything and realize you and your friends now only talk about business.
Don’t forget about the dynamics of when things go wildly successful. Greed can easily take over in friendships and all the sudden someone might talk themselves into believing their friends don’t “deserve” to participate in that success at the same level as themselves.
I clearly don't understand all the dynamics here - but this seems completely ludicrous. So I go away for a weekend, someone breaks into my home, and when I come back I am homeless? Where is the delineation between "someone breaking into my home" and "squatting"?
Sometimes in England a landlord will be attempting to illegally evict a lawful (non-squatting) tenant, so the tenant calls the police for help and is surprised when the police assist in the illegal eviction! Obviously this is not supposed to happen. The police should not be evicting people just because some random told them he owned a property and it was being squatted.
On the other hand, the legal situation for evicting squatters in your home isn't so bad here. You have 28 days after you find out you are being squatted, and the eviction only takes 24 hours.
Unless you register all tenancies with the state (which seems like massive overreach) how can the police quickly determine the lawful possessor?
Property ownership is public information, in the US at least. I bet many/most of these situations could be solved by simply verifying that the evictor is the property owner
To avoid confrontation in the 48h window, a good squatter strategy is to target summer or weekend houses that have typically other weekend houses next to it so that neighbours aren't there and won't alert the owner.
Then squatters move in in two steps. First they do a small break in and leave, observing whether someone notices and fixes the first break in. If the first break in goes unnoticed, it is probably safe to move in, change the locks and squat there permanently as nobody will confront them in the 48h window.
Bringing a toothbrush and knowing your rights. If make it look like you're living there and say you have a verbal agreement, cops will let the courts handle it.
