Downsizing a 500,000 home to a 300,000 home gross releases 200,000 — but transaction costs bite. Estate agent 1.5% (7,500), legal 2,000, transfer tax on the new property (varies), moving 2,000, plus any new-home renovation. Net cash often ends up 10-15% less than the gross gap. Running the numbers before listing prevents surprises.

Run it with sensible defaults

Using current home sale price of 500,000, current mortgage balance of 0, new home price of 300,000, selling costs of 10,000, the calculation works out to 182,000.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Current Home Sale Price, Current Mortgage Balance, New Home Price, Selling Costs, and Buying Costs (incl. tax) — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Net cash = sale proceeds minus mortgage paid off minus selling costs minus new home price minus buying costs. Can be negative if new home costs more than the equity released. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Using this to think, not predict

Financial plans are wrong by month six — new information arrives and reshapes the picture. The point of running projections isn't to be right in ten years; it's to be less wrong in the decision you're making this week.

What this doesn't capture

Real plans get re-run against new information every year or two. The result here is a reasonable direction, not a destination. Treat it as a starting point for thinking, not a commitment to a specific future.

Frequently Asked Questions

What are typical transaction costs?
Selling: 1-2% estate agent + 1,500-3,000 legal. Buying: transfer tax (varies by jurisdiction and price) + 1,500-3,000 legal + survey + moving. Total often 3-5% of property values.
Is the released cash tax-free?
Usually yes for main residence in most jurisdictions (principal residence exemption). Buy-to-let or second homes may trigger capital gains tax.
Does it always make financial sense?
Depends on jurisdiction, lifestyle, and cash need. Running costs drop with a smaller home, but transaction costs eat a chunk. Staying put often wins mathematically — moving has lifestyle reasons that the number doesn't capture.
What about renting after selling?
Different calculation. Compare released cash invested vs rent for remaining years. In high-cost areas selling-and-renting can work; often it doesn't.
