You might call the local housing authority to see if you can get an inspection checklist or if there is one posted. 

While Greece is generally still cheap compared to other European locales, partly as a result of the Global Financial crisis, real estate on the most popular islands like Mykonos, Rhodes or Santorini is actually very expensive - as much as 10,000 euros a square meter.

If you can, attend some local REI meetings.

Then again, the law allows them to set their rate at whatever they want and you agreed to it.I have something similar in my agreements, but it's significantly lower becuase I don't have to market or show the house, there's usually little/no negotiation, and it's basically a paperwork game.

A few years ago I got very interested in Real Estate Investing and connecting with anyone and everyone I could through local groups or individuals.

My wife and I are interested in going in on an investment with my sister and brother-in-law.

Call your local banks.

You're likely to get the best terms at a local or regional bank that keeps their paper and services their debt themselves.  

They’re local investors, run a REI meetup, and all around good guys!

Make sure to connect with local lenders and brokers as it's beneficial for achieving your real estate goals.
