To sum up what everyone is saying and what we do:- notify the tenant to call the police next time to file a noise complaint.- Send emails and texts to all tenants in the building reminding them of "quiet enjoyment" and respectful behavior to their neighbors.- Avoid being the mediator, judge, and jury

I’ve read quite a few posts about foreign investor financing but most seem to deal with non-citizen investors without US credit or personal tax filings.

Quote from @Cheryl Abram: What legal filed docs are LPs entitled to see to help validate a deal's failure?

Typical cost for the setup would be in the $15,000 range which would include production of the Private Placement Memorandum, Subscription Agreement, and Operating Agreement, Investor Qualification Forms, as well as filing Form D with the SEC, and state “Blue Sky” filings in those states where your investors reside.

My “reasoning” is based on two points1- the current system of property records filing in a million different jurisdictions with expensive title searches necessary for almost every title transfer and mistakes still being made can be made much less expensive, much faster, and much more reliable through migration to some sort of “blockchain” National registry.2- Numerous investments have been divided into, and offered as tranches of the whole.
