Still trying to determine my ultimate REI focus ...I'm in my late 20's, married, and thoroughly enjoy racquet sports of any kind (racquetball, tennis, badminton, etc).I love learning and teaching; I value a strong community development where I can trust my neighbours and friends as if they are family.I currently have no real estate experience stateside.

Build a gravel path for the neighbour to access their land and paper it up.

Purchase of a property, for residence or even for an investment required to obtain a residence permit in Greece 

Talk to the neighbours and tell them they are all her family members visiting.

Your immigration laws take people from other countries much easier than your Northern neighbours.

What class of tenant do you believe your neighbours would like to see living next door in their class A community.

My neighbour sold his house a week before the new mortgage rules went into effect for 200K over asking and literally a hundred people went through it, and last week my friend put his house on the market (nice house, great area) and only one party made an off at asking price...telling perhaps, but would be interested to hear what realtors are noticing.

Find out what your neighbours problem is and if in fact your tenant is the problem correct the situation or do not renew their lease.

I am an American citizen living in Greece, looking to invest in the US. 

For example - nobody's quite sure what will happen with Greece and portugal (unstable, recession end date unknown), and are mostly certain the USA will someday bounce back (normally stable, temporarily recessed but with high recovery potential).
