Unfortunately you lost the first battle and the neighbour now believes they own you, and rightly so, they do own you.

I would talk to your neighbour as well and see if they are willing to pitch in. 

A co-worker told me that they purchesed a town house in Greece and that they got a good deal (about $140,000).

As I continue to progress in my financial journey and contemplate my reasons for pursuing early financial independence more carefully, finding my why, it's obvious that the collapse of the Greek economy and the financial distress of my friends and family in Greece has a great deal to do with my mindset.Imagine living in a country where you go to the bank one day and they tell you that you can't draw any of your own money out of your own bank account.

When I did return to the property, the fellow was standing in the freshly shovelled walkway with a big smile ... he had never shovelled snow before (hadn't seen it until he changed planes in MTL), saw what the neighbours were doing, and thought he might clear the walk while he waited.

Hi Jeremy...Regarding your question about people investing in Europe, we are getting good results for properties in Greece, largely due to the quality of the properties, seaside or sea view locations, significantly reduced prices, and last year's launch of the Greek residency visa for non-EU buyers spending at least 250,000 Euros.

I buy them like that but in B class areas and bring them up to standard with the neighbours.

If I tell my neighbour that the house down the street is  for sale,  am I marketing the property? 

You'll have cut-throat competition with your neighbours when you want to rent or sell and you'll have to compete on price, a situation the shrewd investor wants to avoid, especially when it comes to short-term rentals.
