For one thing, when you need or want to say no to something you think it unreasonable, you state it as a rule."

Since it hasn't been mentioned you can bribe them to leave but unless they become a problem, or are dramatically under market rent you are probably wasting money if you do that.Lastly, be careful not to make them jump through unreasonable hoops after title transfer.  

We do itemize our scopes because we believe it brings value to the customer however if a customer wants to rip up most of it and only have us do items that others can't do cheaper then we will no longer be their contractor simple as that as a contractor you have to sometimes fire your unreasonable customers just like at times an investor has to fire an unreasonable contractor...

Searching for markets with properties that meet or exceed the following criteria:- cash-on-cash return of at least 12%- annual appreciation of at least inflation plus 2%-3%- low crime area- strong school system areaAbove targets to be reached after provision for the budget assumptions below:- 10% vacancy- 10% of rent for property management fee- 10% of rent for CAPEX- 5%-10% of rent for general Operating Expenses- 1%-3% of property value for insurance- 1%-3% of property value for taxes- 10% of rent for misc. expense retainer- debt service on 80% leverage Are my expectations unreasonable, or have you experienced/come across properties in locations where I could achieve these targets?

It means the tenant has the right to not have the landlord interfere unreasonably in their possession of the home while they are renting it, their right to quietly enjoy the property without the landlord's interference.I think landlords forget to put themselves into the shoes of a renter. 

Since this was my first toilet I had to replace the price seemed high, but I didn't think it was unreasonable considering how bad the toilet was. 

This is magnified by a great deal when it comes to people that are unreasonable.
