Curious about the reason, I consulted my home insurance broker, who informed me that the property had a water damage claim filed a few months ago, which is causing insurers to be cautious.This information surprised me, as it had not been disclosed by the seller.

Tenants file bankruptcy, go out of business, stop paying, but stay. 

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.

But I noted that places like North Tonawanda as @Pravit Jarriyapurttipong mentioned are actually outside of Erie County, it's in Niagara County, which follows the stricter landlord laws as New York State... https://ag.ny.gov/sites/default/files/changes-in-nys-rent-la...Would you recommend sticking to Erie County boundaries for this purpose?

How many 70+ year old landlords are going to be smacked with a multi million dollar fine for not filing for the last 2 years??

Thank you, Adam  Hey Adam, obviously Bias here as we are accountants, but yes with three properties is definitely worth hiring a CPA or tax specialist that focuses on real estate to ensure all your taxes are filed compliantly, properly, and you're getting all the deductions possible.

It occurred to me today that I've never asked about umbrella insurance claims.I’m particularly interested in real-world examples where this type of policy came through during:Property damage (fires, storms, floods, etc.)Liability claims involving tenants or third partiesMajor unforeseen eventsIf you’ve ever had to file a claim and your umbrella policy saved your bacon, I’d love to hear:What happened?

that will not cash flow - you won't be generating "cash flow" from the property that will go beyond servicing the debt and allow you to pay down any principal. 

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
