Rental Properties in Poland

[Marek Mlynarski]

Good morning everyone, I just recently got into real estate investing and have recently purchased my first property and a friend suggested I look into group. This was before I even knew about BiggerPockets, it’s podcasts, and it’s powerful net of information and people. I began reading one of Brandon Turners books and I stumbled in on a question. When doing all the expense calculations, such as the 50% rule and others to be used in trying to quickly determine if the property is worth looking into, can the same principles apply for when your purchasing a property out of the US. The rates, taxes, insurance, etc, and even currency are different. 
In other words my next outlook on a property would be in Poland Kraków and I’m looking for some advice. 
I will most likely be moving there.
