Hobby landlords tend to approach all aspects of the business from the perspective of doing as little work as absolutely possible in return forfeiting the higher profits. 

Professionally, I have study and working experience in the German Taxation Laws and know that Taxation is a crucial and vital aspect in any business in any country.I already have property here in Germany and currently planning to expand to Dubai and Miami USA. 

If you have done this before, would you mind checking my math and seeing if I'm missing any large aspects? 

This is certainly text book and absolutely the proper way to analyze a deal.Im not sure what he owes on the home but based on the payment and the year it was bought and the fact that its 20 min from Austin im just going to throw out 500K for conversations sake.500K compounding annually at 3% for 5 years comes out to approx $578,000, and you have the loan paydown aspect as well obviously. 

Without commenting as to the ease or difficulty, passive or active aspect, here are a few commercial deals I’ve made outsized profits on in fairly short periods of time.  

@Rick Baggenstoss  "eviction service"   thats useful to hear, thanks for mentioning that "systematizing" aspect that padsplit.com's system provides. 

We are an all-in-one or a one stop shop company, meaning that we handle all aspects of the investment process - Buying, selling, managing, and have the connections and resources to help in any other way.

While this affiliation might bring certain advantages like integration and streamlined services, it’s also worth noting that many tech entrants in the property management sphere sometimes miss the intricacies of real estate management, focusing heavily on financial aspects instead.If you're looking for alternatives, you might want to consider other established platforms that specialize in property management, like AppFolio or Buildium, which are paid services but widely recognized for their comprehensive features and security measures.

The second aspect is how viable it is for me to buy and sell in a particular market that is far away and where I’ve never visited.

It effects every aspect of the property and performance- the type of loans and insurance you need will change if you don't hold the property in your personal name.
