When looking into it, the basement had water damage that didn't worry us since we knew how to remodel that area ourselves.

If all this billions upon billions upon billions of damage WAS because of carbon caused climate change.....

- We had 2 break-in & furnace & HWH thefts there this year:(File a claim ASAP, you'll need:1) Utility bills to prove electric & gas were on2) A police report, proving a break-in3) Pics/video to prove the condition of the property to support theft claimWhat are you doing to mitigate additional damages?

Eats up time and money getting rid of a bad tenant (not to mention possible property damage). 

Quote from @Michael Smythe: @Zachary YoungRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

-When a tenant moved out, the management company refunded their security deposit but failed to account for damage, such as holes in walls and outlets ripped off the walls, leaving me with repair bills and also tenants moving in without the repairs being done.Stuff like this that is consistent and when I ask questions they are defensive, when I ask for more quotes for high ticket items they are defensive. 

Make sure when the new hardware is installed adjustments are made if needed and repair any damage to door jamb. 

They are far more common now and harder to find models without but:1) these add cost to the purchase price2) they don't bring a lot of value3) they can leak or detach and damage the propertyI own around 50 doors and I cap off the line at the wall or in the basement with a valve and a cap so the potential for leaks is 0.00001% :-) 

, because they had added a provision to their lease that conflicted with State law - even as there was no damage to the tenant!

-Outlines what is considered damage to linens and other personal property (ie., stains, etc)-MTR we are flexible on the lease end date and will prorate last month's rent.
