It would encourage managers to place better tenants from the beginning.

I'm hoping to find a good deal on a duplex that's either already occupied or with the hopes of living in one unit and renting the other out.All advice and words of encouragement are welcomed :) I am new so please provide information in that instance!

Only thing the property manager can do is 'encourage' him to pay and be nice to him, but be a nuisance. 

I personally would encourage it, as I know it has worked out for others as well.

BUT I also want to encourage you to think about LLC w/more open eyes.I have been investing in RE for 18 years. 

Encourage them to bring somone bilingual to the contract signing if they are the successful candidates. 

Now, I encourage anyone to do all of those things, but today we will not be taking that deep dive.

I encourage cash payment for deposit and first months rent.

I'd also encourage you to look at house hacking a duplex or other type of property if you have not already. 

I would encourage him to network with other local investors and keep learning through any means: youtube, podcasts, books, mentors, etc..
