Starting with current expenses (Option 3 - continue working):

***Healthcare, taxes, retirement investments taken out of paychecks

Option 1 - FIRE, sell primary residence, move to lake full time, don't rent house, live off savings, and work part time
Income: Live off investments/savings
Healthcare (depending on income level): as high as $1300K per month w/ less income and tax credits it could be lower
Property insurance: $100 per month
Utilities on lake house (TAXES, heat, electric, cable, etc): $1200 per month

Gas: $200 per month
Travel/Vacations: $200 per month
Home improvements (1% of home value): $250 per month

TOTAL Expenses: $4600 per month
Option 2 - FIRE, sell primary residence, buy ski house, use both homes as vacation rentals, live off savings and rental income, and work part time. Income in this case is currently more fussy due to rental income, but I'm continuing to research the details. The ski rental is clearer as its in an area with many rentals and many with rental track records. The lake rental is in an area of many lakes with rentals and rental track records, but our particular lake has only one other property available
Income: Estimating rental income of 3.5K per month (which we think will be on the very low end, but we'd rather be very conservative)
