Personally, I don't charge my clients for answering normal, routine questions they ask (I would consider your question normal and routine) for two reasons:1.

They seemed to be happy and they nodded in understanding.THE SECOND MONTHSomehow during the Second Month, when the newness wears off and the happiness falls into a routine, the new Tenants become confused.

Rent controls or other local laws and ordinances are just that, Local, and you need to review the enabling authority for specifics.As a PM, I routinely run background checks on all applicants, and our policy is that not only will we not rent to someone with felony arrests, we will not rent to any violent offenders, drug offenders, sex offenders, GTA or petty thieves either!

Many of these groups manage both affordable and market rate however have a great deal of experience screening tenants and conducting routine unit inspections which it sounds like is a major issue with your existing company.

I routinely tell even married couples not to buy investment properties together (example from 10 seconds ago).

Or, a charging order may be granted.If you're going the umbrella insurance route, perhaps see if it will cover you for several things including just the routine slip and fall (like mold or earthquake).

If a routine maintenance list was in place, this would have been avoided. 

The party issue or just noisy groups that annoy sensitive neighbors was a fairly routine problem with the medium and large house.I think it kind of comes down to operational style also.

The 24 inch units don't have great capacity and are best suited for a 1 bedroom unit.If you get washers/dryers that are too small, tenants will overload them routinely and shorten the life of the appliances.

Congrats, you will feel a lot better about yourself and your business once you whip them into shape.And next time you will jump on it immediately simply as a routine part of operating your business.
