-Cons Cleveland itself has mandatory lead testing ( mixed bag there) But that's only Cleveland properAging Housing stock, so more maintenanceCleveland proper is tough for evictionsThere's a lot of opportunity in our inner ring suburbs and Cleveland itself.You forgot to mention that Cleveland holds a Dopeness level of level 10. 

Smaller market but if cash flow is your bag, I'd look at Lawton, OK.

But hard not to see mass layoffs in the next 6 months causing a recession.Obviously, doesn't mean that'll affect RE prices unless many tenants default and over-leveraged landlords (again) are left holding the bag.

I just talked recently to my sister-in-law with a similar issue you can't just add on anything about the trampoline to the least you can't do that legally she's a real estate attorney you can't legally add it on and technically a trampoline is not a toy it is a workout type of machinery it's almost like having a set of Weights outside or a punching bag if it's not specified already in the lease before you gave it to him legally there's nothing you can do and it would be extremely illegal to just add it in after they were already there and sign the lease you can't add into the next lease it's not how it works now if you had a apartment complex that would be different but if you're renting a home would they put in their backyard is none of your business they're renting your the home from you you can't control somebody's yard you can say yes you need to keep it clean but you can't tell them they can't have a trampoline or a swing set or any of the above in their backyard if they're running a home from you by law.

Does providing complementally k-cups/teas, popcorn, spices, toiletry essentials (toothbrushes, floss, bath wash, shampoo, conditioner, soap, paper products, makeup remover, laundry detergent, firewood with firestarters for the fireplace and firepit constitute as substantial services?

My tenants expected me to leave cleaning supplies and trash bags as well (SRO building).

The units are heavy and feel very secure, and are much easier to install than any others I have encountered.This has worked well for me with 2 triplexes each with a common entry door, but we are adding to our portfolio and I may be using the landlord locks recommended above in the future- it would be nice to have less keys jingling away in my bag!

If you think that their activities go beyond recreational use (large quantities in the house, visible scales or bags, people coming and going in excess) it's time for a more serious conversation. 

This is my most effective tool un my tool bag.

Like someone that would not likely walk off and leave you holding the bag?
