As a homeowner, there really isn't that much maintenance costs on a month to month basis.
Maybe something needs replacing every 2-3 years that would be considered a significant cost to repair/replace, like a furnace or major appliance, but for the most part you'll go months without dipping into any money you have put aside for maintenance needs.
So that 24% "profit" will be legit profit more times than not.
BUT... I would keep about 10 grand aside in an "oh shit" account, just incase something like a pipe burst or the furnace craps out.
It takes zero effort to be a good person.
