There are a lot of factors that will come into play when the IRS considers whether someone is an employee or a contractor, and "who purchases the materials" is just one of them. 

That'll help you factor any foreseeable repairs into your budget. 

I believe I understand what the commenters are saying - don't factor in your living expenses because that may make a deal look more attractive, and you may pay more than you need to on a house...

There are two factors at play here. 

All I can think about is the "hassle factor" associated with having to furnish a property from another country. 

What are the risks and based on the numbers and other factors (described above), should I even do this project?

Do you think this factor can be a deal breaker when I am searching for potential rental properties? 

There are a lot of factors that go into a good investment, and while the market is critical a provider can make or break your investment.  

I factor in 5-10% for repairs and maintenance in my head though.
