God if it were a year ago I would be in the exact situation where I could do it. Alas, I like my family too much to either expose them to the ongoing nightmare we face or else change my name legally and alienate them forever. I imagine having a job outside of kiwifarms would be necessary, I wouldn't want to ask josh to pay for literally all of my living expenses, housing costs and free internet are more than enough.
Other Kiwis have mentioned starting a small business of some variety in a small town in one of these states, and that might be your best option. Bartering tenancy for agent services is going to end in a clusterfuck guaranteed, and the law will be on the side of the tenant. Having a business with a small office though? That would A. Mitigate doxxing and swatting incidents, as it's not somebodys place of residence. B. it would give you a platform to expand your business ventures/current operations involving the farms. C. It would prevent you from having to pay unexpected housing related costs. In the arrangement as you proposed it, YOU would be the landlord, with responsibility towards a tenant, meaning if the heater goes out, the water pump shits itself, the septic tank blows or backs up, you would be in charge of handling it. And not to PL too much, but I have experience with areas like the ones your suggesting, and there is a fucking reason these places have stayed cheap despite the housing market being what it is right now, these places are shithole central, nothing new has been built there for 50 years or more when it comes to residential buildings, these places are fixer uppers at best and hovels so squalid the only reason they haven't been condemned yet is because the housing inspector couldn't be fucked to do it, in which case the attention that running the kiwifarms mail out of this place would bring runs the risk of having your property condemned, which you absolutely do not want to be handling from Serbia.
I understand being autistic about who represents you, and I understand wanting to have more control over this than a traditional arrangement gives you, but if you are going to go through with something like this Josh, you need to think it through and do it right, the kiwihaus WILL end in a legendary clusterfuck, the KiwiCorp LLC COULD end in a massive win for free speech, internet freedom, and your bank account if executed correctly.
