For example, being a licensed RE broker, you have to always be aware of the laws and even asking something as subtle as “where are you from?”

People won't always understand that or be aware there's more to your life and business than just them and their property.

Seller owns property outright. house has probs I am aware of, probably more so than seller.

I think you are aware we've worked with all these mentioned builders and can provide more detailed insight into actual specific track record, performance metrics, communication, build quality, delays, price escalations, financing options, build quality, etc. 

I was reading some blogs and nearly all blogs say that for any lawsuit to go through, the landlord must have been aware of the situation and neglected the issue or did not fix the issue.

Happy to help if needed, just wanted you to be aware.

Now the tenant is aware and potentially responsible for any damage to the unit.  

@Matthew Powell yes you can transfer the property but if you have a loan be aware of the dreaded due on sale clause and look into it further if that is a concern.

When I have a property that is mixed smoking/non-smoking, we discuss with prospective tenants to make them aware that the property is transitioning to non-smoking, that it is in the rental agreement that there is no smoking within their unit or common areas, but acknowledge that there may be smoke on the premises in other units.  

@Brian Crowe There are two kinds of water accounts:Lienable and not lienable.Not lienable are on the tenant.The ones that you are talking about are ones that are lienable, usually if you deal with tenants you should be aware of it and put the utilities on the property name and charge the tenants separately for it.Just pay it and take it as a learning experience, it will be a waste of time suing the tenants.
