We also see spending habits such as $ spent at pet stores, rent payments amounts and when they pay it.

I understand smoking, pets, subletting and the like.Also, would restricting cryptocurrency mining or electric scooters/bikes be appropriate?

Me: "And how about pets?"

   " Oh no we have 2 nice dogs "   I tell them , "i guess you didnt read the add where "NO PETS " was on the first line "  .     

I drove the 3 hrs to look and found:Evidence dogs resided at the property when the lease said no pets (I did some research and found pics of tenants with the dogs in the home), dirty and scratched drywall, red screws in the walls in several rooms, unchanged HVAC filters, carpet stain, and filthy appliances.These aren't the only times and I tried to keep it short for your reading.   

Be fair, caring, and understanding, but be firm.3) Everyone has a pet.

My wanting to help out some young people (the first time) resulted in police on site for domestic abuse, social services checking on child welfare, non-payments and about $2500 in damages after they finally left (holes punched into walls, damaged carpets, etc)I'm not saying don't take a chance, but make sure the rental rate is not lower than the market (which attracts undesirables at times), and do your due diligence!  

Lower is 2 bed 1 bath $1425/mo with pet.

We also had a stabbing, plenty of domestic violence, plenty of evictions, drugs, fights, a slip and fall lawsuit, the two OD’s, etc. just tons of drama in that building. 

. -- The unit still needs to be furnished, however, you can charge a premium and not worry about irresponsible renters or pets. -- Some buildings require a 12 month min lease and to get around that, you can include a bump-out clause allowing a renter to leave early if need be.
