I have had unwanted people come into my house and my dog jumps up and without barking but wagging his tail thinking whoever it is, will take him for a walk or a ride in their car.  

I've also seen "sound machines" advertised at places like Walmart that are supposed to help block out unwanted noise, but I've never tried one.

The mere fact that someone is not on title marketing a property is likely to eventually draw unwanted scrutiny and legal hassles.

any follow up on buying redemention rights prior to the sale I know there is a lot of talk about some of the bigger players here getting some unwanted attention.Having dealt personally with Oregon regulators @Ned Carey   Ned is very correct their interpretation and yours or your attorneys  can be vastly different just depends on the situation. 

You said getting new tenants is not a problem, so unless it is an unwanted hassle to that's probably your best option.You do away with the maintenance and upkeep of the machines, the utility expenses and if you're right about neighbors using the laundry reduce the traffic onto your property which can only be a good thing.

For my own organisation, I've decided to summarize below...

Obviously, you will need to find a solicitor in the Netherlands who can help you optimize an organisation and tell you the expect costs to establish and maintain it.Tot ziens,

So the real question on my mind is not how effective are these services at triggering a response, but why any of us would want to build a business already walking a thin line of legality and generally unwanted by 70% of the general population? 

Start with a real estate guy - they usually have the business side as well and are familiar with typical business organisations for investors.

Try not to follow me, though - unless you want unwanted advice on meth labs, cheap wine and public records.
