When to Run Horizon Point
Five real-estate moments where the break-even year actually changes the decision.
Horizon Point isn't a vibe check — it's a 30-year projection. Run it at these five life moments.
First-time buyers run Horizon Point once and then forget it exists. But rates move, rents move, and the break-even year moves with them. These five moments mean rerun the math.
Quick answer
Horizon Point isn't a vibe check — it's a 30-year projection. Run it at these five life moments.
Key points
- ▸ Before any home purchase: know the break-even year before signing. If your stay is likely shorter, renting is often cheaper.
- ▸ After mortgage rate changes of 1%+: a rate drop moves break-even earlier; a rate rise pushes it later. Big moves flip verdicts.
- ▸ Before a job relocation: the "how long will I stay?" question becomes concrete. Run Horizon Point at the new city's prices.
- ▸ After rent hikes: if your local rent jumped 15%, cumulative rent line steepens. Break-even may have moved into your actual tenure window.
- ▸ Staying vs selling (existing owners): rerun Horizon Point with your remaining mortgage as the "home price" and current rent as the alternative. Sometimes selling wins.
- ▸ Annually regardless: drift matters. Property taxes, maintenance creep, and local rent shifts all change the curves.
Examples
- Pre-purchase triggerOffer under consideration: Horizon Point ~year 9 given appreciation estimate. Planning to stay 4-5 years. Rent is cheaper — walk away or negotiate harder.
- Rate-change triggerRates dropped from 7.5% to 5.5%. Horizon Point on same home moves from year 11 to year 6. Now the purchase pencils out for planned 7-year tenure.
- Relocation triggerMoving to a high-rent, low-appreciation market. Horizon Point in new city: 18+ years. Rent there for the 4-year stint instead of buying.

Frequently asked questions
› How should appreciation assumptions change by market? How-to
Historical long-run US average is ~3% real. Use 1-2% for flat markets, 4-5% for hot metros (with caveats). Never use recent 2-3 year numbers as projection — they mean-revert.
› What about rental inflation?
If your tool supports it, model 2-3%/yr rent growth. It accelerates the cumulative-rent line and brings break-even earlier.
› How should I use a decision framework in real life? How-to
Use a decision framework to expose the tradeoff, not to outsource the decision. Write down the inputs, compare the output with your constraints, then ask what would change the answer. The strongest use is scenario testing: base case, conservative case, and failure case.
› Is this financial, legal, or tax advice? Trust & accuracy
No, this is not legal, financial, tax, medical, or professional advice unless the page explicitly says that use case is supported. It organizes assumptions so you can inspect them. Verify high-stakes choices with qualified people who can review facts, contracts, regulations, and downside risk.
› What assumption matters most in a decision model? Edge case
The most important assumption is usually the one you are least certain about and most emotionally attached to. Change that input first. If the recommendation flips after a small change, the decision is fragile and needs more evidence before you treat the model as useful.
