There is a lot to consider beyond what you've stated and as already said, it's 25 months, not years, but not really.
The rental income doesn't just go to the cost of the repairs, there are property taxes, income tax, insurance, mortgage (if any), any applicable utilities, and any other routine maintenance costs to consider before knowing how much profit there is to apply to the estimated 30,000 cost recovery. And even that's not quite complete because the taxes will be a little lower each year due to less profit and the deductible expenses.
Then there is the appreciation of the property, is the value steadily climbing and if so, what kind of yield might be expected by holding on to the property? Even if you're out of a rental profit for a while (with the associated risk of some other unforeseen repair) you still might make out on appreciation, if there is significant appreciation.
What is the tax basis of the property for computing capital gains? If your cost basis in the property was say, $50,000 and you netted $125,000 for the sale, assuming you are in the 15% capital gains tax bracket then there would be 15% to pay on a profit of $75,000 = $11,250
Capital gains is taxed at 15% (if that is your rate) but the profit also is counted for AGI type calculations, for things like how much money you made to determine medicare premiums (IRMMA income thresholds). At least at your age you don't have to worry about that but the AGI change is something to be aware of.
The current Trump tax cuts for the middle class expire at the end of 2025. Will the capital gains still be 15% in 2026 or will it be maybe higher, along with taxes in general? There is no way to be sure. But again something to think about. Especially after the election, if you don't sell before it.
These are the thoughts that go through my mind (the question strikes close to home), obviously how they might apply to you could differ.
