Event though my STR's and MTR's are in safe neighborhoods, I chose to install cameras in order to "keep honest people honest".   

Keep in mind the owner still has to pay for lawn maintenance, utilities, cable etc...

doing some research for an upcoming presentation, and as a hands-ON investor, it can be hard for me to really put my 'hands-OFF hat' on and compare passive investing vehicles without any bias. i'd love to hear especially from those who have tried multiple strategies, which of these you lean towards most & why:- syndications- REITs- private lending- being a hands-off capital partner- buying from turnkey companies (not sure i'd call this passive though)...

I thought about buying a multi family (maybe 4 unit) and keeping one for myself and then renting out the other 3. 

Come humbly from a position of knowledge and strength and you'll find all the help you need.Good luck, and keep moving forward!

I'll keep updating on here.

Also, it generally exists only because some landlords keep their property empty or if long-term tenants become delinquent, don't pay and turn into squatters.

If it's a golden piece of real estate like you said it is and you guys are all motivated, mentally and physically capable, I would keep this golden goose egg all to yourself. 

I am not against it for the right person, but many people think that its a great way to get into real estate when you have no money and cannot qualify for a traditional loan, in that instance, its a really bad idea and mostly does not end well. 100% agree keep in mind some folks may have been transferred and their current home is not sold yet..

If I get an answer of "a month's rent to place a tenant, 20% of rents and I keep all the late fees", then there wouldn't be any additional questions from me and we'd both save time.
