What about medical/health expenditures, car maintenance, clothes, gifts, household supplies, eating out, vacation, etc.? I don't think you've truly captured all of your expenses here. Try using mint.com or some other tool to really capture your spending.
Also, I'm not a rental property expert, but you are barely cash flow positive on the property, much less allowing for vacancies, expenses for repairs, etc.
You have a nice positive net worth but a lot of it is wrapped up in your primary residence. Will you be moving once you retire or do you want to stay in your house?
