Sell rental to invest in stock market?

[Bill Ward]

I currently rent one single family home, and been playing with the rough numbers in my head. In a about 10 years the house will be paid off, rent will be roughly $1500 a month by then I'm guessing. So I'd be making $18,000 before taxes, repairs, maintenance etc on the house. So let's say net $10k a year. If I were to sell the property then for $150k and invest that in stocks and the markets been averaging 6% a year, that's $9k the first year and then more every year. That includes no landlord or property management tasks or headaches and is completely passive. Am I missing something? Does each property have a tipping point where its worth selling to invest and avoid the hassles and time of renting?

Thanks,

Bill
