I'm confused -- looks like your future gross income is $103K, and you have listed over $110K in expenses/savings ($74K expenses + $22K 401(k)s + $6.7K HSA + $8K Roths). So where is that delta coming from? Also, what about life/disability insurance, car insurance, etc.?
The other thing I would encourage you to think about is periodic replacement of things -- e.g., at some point between now and FIRE, you are likely to need a new car or two; you are doing a reno now, which will get your house set for a few years, but you will still need to replace appliances and roofs and such over time (the average lifespan for appliances is sort of ridiculous, like 7-13 years), replace carpeting, repaint, etc. -- and with two properties, that is going to be even more of an ongoing expense. I would recommend planning some sort of "sinking" fund for these periodic replacements, both in your current budget and in your FIRE budget, because those things never go away.
