Interestingly, these clients are also looking in Astoria which I still think has decent upside plus also has already strong renter demand, but everyone has tastes on Brooklyn Vs.

This has given many a very bad taste in their mouth against outsiders.

My one commercial experience was a two-tenant (restaurant and dry cleaner) that left a bad taste, and I haven't been back since. 

I got a taste of being a landlord and doing a rehab myself... and I got to live for free for a little while, until I moved onto my next house!

No disrespect to some of the above suggestions BUT contacting someone via Airbnb to inquire into buying their property is rather in poor taste in my opinion and comes off unprofessional if not offensive.

I’ve looked into the wholesaling think and it looks interesting but it is too close to criminal activity (my opinion, of course) for my tastes.

You would live on site and you'd get a good taste for what it's like being a landlord.

If they don't change the fridge's water filter, the worst that will usually happen is they'll probably end up with funny tasting/smelling water.I have another lease that's a custom lease written up by an attorney, and has a clause that specifically addresses HVAC filters:AIR FILTER REPLACEMENT AND/OR MAINTENANCE RESPONSIBILITY [Landlord check this box if applicable]  The premises is supplied with a replaceable air filter as part of the HVAC system.

Did not intent to house hack, but took a leap of faith which gave me a taste of an additional stream of income, which as since resulted in me becoming a Bigger Pockets pro member and daily searched for my next investment.
