If there is mold in the bathroom because of their issue (not running the fan or high usage), then let them know that they need to clean the walls more often. 

Obviously, that's up to you.And, not for nothing, but a lot of vacation rental companies lay out the number of "owner weeks" for property usage.

and that the utility usage has escalated.. that you would like an additional like $25.00 per month if they continue to use the washer and dryer as they had not informed you prior to installing them... as far as hook up for the appliances I doubt you had a dryer vent just hanging there.. so this was not a approved addition.

@Jon S.I agree there is some usage in RE and Blockchain is not a bubble, it will have plenty of uses.

Hello, I'm conducting a study on the usage of property management software for apartment owners & property managers.

Should have 12 month usage on it7.  

What was once a full day job at our larger parks is now a 20 minute process and the water usage is automatically populated to each resident's bill in the software.  

I understand these cities have a housing crisis, but to remove a legal usage after purchase seems very wrong.

You will get far more money as a Flex building.Door height and Ceiling clearance height dictates usage.

Trust me, it is my neighbors who fight tooth and nail against new housing in "appropriate" areas.
