It probably would have cost me about $10k more, but I would have still been able to secure the property.

What is the average acquisition cost of the houses?

Rental income is subject to tax, but it is also possible to deduct many costs related to owning and maintaining rental property, including property management fees, repairs, and mortgage interest payments.Additionally, for those investors holding properties in Germany for the long-term, the country's capital gains tax law is attractive.

In the beginning I want to manage by myself to save cost.

I would include servicing costs of the loan and licensing costs.

And that depends on how you view the costs. 

If you don't, it can cost you everything!

My lease requires professional carpet cleaning, which would cost more than $500 for a home of that size.Yes, it's reasonable to reduce the cost because she was such a long-term tenant.
