@David Herfel, connect with an investor-focused real estate agent in your respective market who has house hack before or routinely helps and services house-hack buyers.

Whether it’s through customer databases, CRM platforms, property management software, or digital marketing efforts, real estate companies routinely gather personal and financial data for sales, leasing, and property management.

I will grab both of those books and stir it into my morning routine. 

The good news is that the financial metrics you've read about are universal and not at all country specific.The bad news is that Germany may just not be a good cash-flow market, compared to the U.S.But then, few markets are.That's why you find so many Germans and Australians and Spaniards and others trying so hard to find great deals in the U.S.And, even in the States, there are plenty of sub-markets where properties routinely fail the so-called "1% rule."

Timing the lock still doesn't prevent them from showing up early and making current guests uncomfortable.

So telling my tenant to pay, get emails from, and use an app called "LANDLORD studio" does make me feel uncomfortable to some degree as it makes it sound more like a 1 sided transaction. 

Meaning how long should I expect to wait for routine repairs to be made?

The more uncomfortable you're willing to live, the better the numbers will be.

What you can do right now is connect with an investor-focused real estate agent who has house hacked before or is house hacking now and routinely works with other house hack buyers.
