The freaking out tenant and whatever happened can be resolved after I get my shut-eye.And the only housewarming gift I strongly suggest you give your tenants, is a new toilet plunger you leave by the toilets.

Should she keep her mouth shut and let them learn the hard way since it's not her place to advise her landlord?  

Cleared cache, cookies, shut down computer, etc.  

When you go over the lease, provide them a tenant instruction sheet with your welcome packet that explains:- how they can pay rent- how to make a repair request- watering restrictions- how to operate unit's HVAC, thermostat, care of garbage disposal, location of main water shut off, gas shut off, breaker box- numbers or links to turn on/transfer utility accounts- how your city enforces noise ordinances and how this may effect those who violate it (BTW, your tenant  blasting his music so it can be heard at by other residents on the block  at 10 am is just as bad as if he is doing it at 4 in the morning). - anything else you feel tenant should knowOthers have given you some great suggestions for collecting rent automatically.

This almost happened to my friend in his large, posh SF apartment (they're pretty sloppy in the bigger places)--The office gave him a lower renewal rent lease and he was about to sign (and looking up legal rules if he should say anything or just keep his mouth shut and sign) but then they ran back to change it.As @Kathy Johnson mentioned, there needs to be consideration (they need to give you some amount of money for the contract to be valid-- same as when you put in an earnest deposit-- you can't just give $1 as that likely won't be upheld as real "consideration" in court). 

Landlord Emergencies call the above Number within x hours of loss of heat, significant water leaks you can't shut off.    911 Emergencies: For Smoke, Fire, or altercations with your roommate-- Don't call the landlord Call 911 and leave!

When I asked hee for her rent the other day(via text) her response was that she isn't getting paid because the world is shut down and that she has nothing.

@Theresa Harris Thankfully they indicated a specific date and have utilities set to shut off as well so that should make turn over clean at least.

@Patrick OwensScrew the gate shut.

People made bad choices and they told people who warned them to shut up.
