What if I sold a property?
Selling looks like a single number arriving in one month, and it is mostly everything around that number: the mortgage that is settled first, the costs that stop, the housing that has to replace it, and where the remainder ends up.
What shapes the result
- The net proceeds you expect after selling costs and any tax that applies to you.
- The month of the sale, and the mortgage balance that is settled at completion.
- Ownership costs that genuinely stop — insurance, repairs, building fees, property tax.
- Rent or replacement housing costs that start instead, and the month they begin.
- Where the remaining proceeds go, and whether any of them are already committed.
Keep and sell, over the same years
Leave one copy of the plan owning the property and sell it in the other, over the same horizon. The temptation is to remove the ownership costs and stop there; if you sell the home you live in, something has to house you afterwards, and that cost belongs in the same copy.
Read the years after the sale, not the month of it. A large sum arriving is easy to like on screen; what matters is whether the plan is better off five and ten years later, once the replacement housing, the lost rent and the new allocation have all been running for a while.
Questions worth testing
- What is left after the mortgage, the selling costs and the tax you accounted for?
- Which costs actually stop, and which of them quietly continue?
- How does the plan look ten years after the sale, rather than in the month of it?
- If the sale price came in lower than you entered, would the decision still hold?
How to read the result
Enter the proceeds you expect after costs and after any tax that applies to you. Worthifi does not calculate tax on a property sale, applies no time test, exemption or reinvestment rule, and neither values the property nor forecasts what it would sell for. Confirm your own position with a tax adviser. This is a planning illustration, not property, tax or investment advice.
How it works in the app
Selling an asset pays off any linked mortgage first, then lets you choose where the net proceeds go — mostly investments, 50/50, mostly savings, or a custom split. An underwater sale honestly leaves the remainder as a standalone debt, rather than making it disappear.
- Tap “Sell an asset” and choose the property.
- Set the sale price and how the net proceeds should be allocated.
- Check the drop in passive cashflow (from losing the rent) and the change in net worth.
