Going with the few details you have given us I certainly see some red flags.
1 Networth: 430,000 but 260,000 is your rental house, that doesn't make you any money at the moment.
2 Rental: You break even? So you don't make any money on this other than any equity you may have in it? What do you mean with break even? IE is the mortgage, insurance, taxes 1400/month and you rent it at 1400/month?
3 Expenses: You claim 17,400/yr in rent and total expenses of 26,000. Does that include the rent? Otherwise very impressive with owning a car and a child.
4 We, We, We: Who is we, what do they earn? You only list your income, atleast you use "I" when you listed 91,000,
5 Income: 91,000 post or pre deduction?
So can when can you retire? If you could get your spending down to around 10,000 you could retire now. If you actually make money on your rental you could spend more. If you sell your rental you could spend around 17,000/yr and retire.
BUT if all you are looking for is a buffer to not work for a few years and stay home with your kid. Yes you have a buffer, but you will need to eat into your savings in order to maintain your lifestyle, or if you clairfy #4 above you might not need to eat your savings at all.
