Homes under $30,000

[Lee Sal]

Hi there,

I am a 29 year old Australian looking to move over to the US to invest in residential properties. The aim is to buy properties under $30,000 with cash and lease out the properties for a positive cash-flow. 

My business partner and I should have around $100,000 between us to invest with. So we are hoping to purchase 3-4 properties to lease out. 

I have seen online many decent properties for sale under $30,000 in cities like Baltimore and Phoenix. 

Any advice on which cities to invest in?

I know in countries like New Zealand and the UK that it is common to rent out individual rooms within houses to gain the maximum amount of rent. Is this a renting culture that Americans also adopt? Perhaps around Colleges for students?

Any advice would be grateful
