I agree with Randy, and on top of that, for another layer of safety I would say before taking any action, you could try and reach out to the bank to explain your intentions.

I notice a lot of these medical professionals are looking for an economic stay and would rent a room to save some money during their contract term.My question is this: If I'm renting by the room, but I'm not present on the property - how can I manage guest interaction and set up some layers of safety checks/balances? 

Which camera or system would you recommend to protect or monitor the site for safety and optionally double as a tool to check for trespassing / capture work progress

When at your home they approach you aggressively and make threatening comments; send harassing emails; don't allow peaceful enjoyment of your home; forced to move into a hotel due to their threats; spoke with officer XYZ on this date and he was concerned enough for my physical safety that he offered me a police escort just to enter my own home...You can also try to contact them and offer to break the lease with no penalty.

If the deck in back is in good condition, paint it black and add a safety rail for the stairs going to the basement.

Prioritizing cash flow, equity, STR, buy/hold, self managing, etc.

(Obviously scaling w/ Sub-To would negate the safety I just outlined but right now my concern is getting started with 1 or 2 properties).

This isn't just about keeping things organized; it's your safety net if things escalate legally.Legal Grounds Check: It's wise to touch base with a legal expert familiar with your local landlord-tenant laws.

(We will hire pros when and if needed for safety of course!) 

Regardless, I wish everyone great success and safety, regardless of the road they take!
