@reeshau has very good advice -- we need a lot more information to be helpful.
The one big-picture thing I'd add is to stop thinking so much about the "right" asset allocation, or when is the right time to be in or out of a particular asset class (which, btw, is better known as "timing the market"). You have much bigger questions to iron out first. Such as:
1. How much do you spend now? Is that based on tracking how much you spend, or are you just assuming? If assuming, please start tracking everything now. You will be surprised how much money is just disappearing on stuff you can't even remember.
2. How will that change when you retire? What are you thinking for medical insurance? Any hobbies, travel, plans to move to a new area, etc.?
3. What other big expenses do you see happening after you retire? E.g., do you still have kids at home, and if so what are your plans for college or other future kid expenses? Do you have a pot of money set aside for home repairs, car replacements, etc. -- or if not, are those expenses accounted for in your future budget?
Once you get a sense of what your annual spend will be when you retire, you can start figuring out how much you need to have invested, and how much more you need to be saving between now and then. That's the only way to tell if you're on track. Generally, the rule is to multiply your projected annual spending by 25 to tell you how much you need to have to fund your retirement. Since part of your money is in rental property, you'd first subtract the net rental income from your annual needs, and then multiply the remainder by 25. (As noted above, do NOT include the value of your home in that -- the 4% rule is based on your invested assets only).
There are many other ways you can tackle this to refine your analysis (for ex., to include things like SS/pension, if you have them). But until you've done the first part, it's hard for us to give you any advice; for all we know, you could be good to FIRE now, or you could be on track to need to work for another 20 years. It all depends on your lifestyle.
Finally, if you are looking to rely on real estate to provide an ongoing income stream, do a LOT of research on identifying a good rental, and on figuring out how much you should assume for things like ongoing maintenance and vacancies and such. Managing real estate is a full-time job, so spend some time investigating that while you still have your salary coming in before you jump.
