So far the only challenge has been many of the tenants do not speak English, so navigating that aspect.

Any English teachers? 

The crew investors use you would never find them on Yelp and only main guy speaks English. 

Finally the owner got involved and did not renew their lease.He is Arabic and his English is not great.

Get a copy of the law, watch your attorney, and translate it into plain English so you can reference it and navigate this on your own next time.I highly recommend "Every Landlord's Legal Guide" by NOLO.

The remaining rest of the family will stay in that unit but I only communicate through the annoying tenant as no one else speaks English.

He is Brazilian and fluent in English, Spanish, and Portuguese.

Either self-manage like many on here do, or hire an inexpensive offshore PM who works US hours & speaks eloquent English (that’s what I do).

Yes, there are For Rent signs in the window (in English and Spanish) and an Info Tube with fliers on the porch railing.

Best part, tenants who had very poor English, were then trying to put on best act they could of "oh, what is this, how long has this been here" acting as if they had no idea all this was in there basement.
