Buying a rental property a very simple form of startup for the unskilled, requiring a very high startup cost for a small return.
I bought a house one year ago, spent $200k and then another $50k in repairs, and now I'm renting it at $1500 a month ($1200 profit after property taxes and miscellaneous)
On the other hand, I also started a new company about a year ago, spent $0 upfront investment, $50 in monthly hosting costs, and it is earning a monthly profit of $2000 currently.
