It's not a difficult concept to understand, but there are just way too many people running around with the "woe is me", entitled attitude.Earlier this year, I had a tenant whose adult daughter (living there) had lost her job. 

The adult son has a good credit score"Me,"Can the adult son qualify on his own?

We will have another two months of shutdowns In California, Most tenants will get $1200 per adult one of our tenants will get $3900 since its two adults with 3 kids.

For example, if I were designing such a model and had all the data available to me, I would include distance to a highway as a feature, school quality, or even creative variables like the count of liquor stores in close proximity, income of zip code, average age of neighbors (to know whether they're adults and poor or maybe just students)...

Please tell me about your job (each adult).

It is courteous if the landlord or tenant provides a reminder before the end of the tenancy agreement.Ending a periodic termA landlord may end a periodic tenancy if:the landlord or a relative of the landlord wants to move in‘relative’ includes any relative by blood, marriage, adoption or adult interdependent relationshipthe landlord agrees to sell the rental premises, all conditions of the sales agreement have been satisfied or waived and the buyer or a relative of the buyer wants to move inthe buyer must ask the landlord in writing to give the tenant a notice to end the tenancythe landlord intends to demolish the rental premisesthe rental premises are a detached or semi-detached dwelling or one condominium unit and the landlord agrees to sell the rental premises and all conditions of the sales agreement have been satisfied or waivedin these cases, the buyer must ask the landlord in writing to give the tenant a notice to end the tenancyneither the buyer nor the buyer’s relatives have to occupy the rental premisesthe landlord is an educational institution, and the tenant was a student at the beginning of the tenancy but is no longer a studentthe landlord intends to use or rent the rental premises for a non-residential purposeIf a landlord intends to do major renovations that require the rental premises to be vacant or the landlord intends to convert the premises to a condo unit, the landlord must give the tenant one year’s notice to terminate the periodic tenancy.

We use Autohost to automate this process via an online check-in system: https://www.autohost.ai/You can also use it to gather additional information and place a hold on their credit card, similar to a hotel.The one downside of Autohost, is that it doesn't have an automated way to collect the ID for all the adult guests (although it collects names + email from the guest).Finally, Autohost can also be used to have the guests sign your rental agreement and agree to your house rules. 

I understand him wanting more for the property but he should've at least acted like an adult and informed you of his decision. 

And the only job losses that result from raising the minimum wage are youth jobs and that's because adults will take them if they pay well enough to make them worthwhile.

I doubt reasoning with them will help if they are adults who are stomping around their apartment just to spite you.
