House Hacking
House hacking is buying a property, living in part of it, and renting the rest to reduce housing cost and build investor reps.
Why it matters
house hacking matters because it links the strategy to cost basis, execution risk, financing, and actual investor returns.
Worked example
In underwriting, tag house hacking beside the exact source input and rerun the model when that input changes. The point is not a pretty metric; it is a better buy, hold, refinance, or walk decision.
How investors read it
Use it to kill bad deals quickly. If the back-of-envelope version does not survive conservative assumptions, do not spend five hours making it look alive.
Common mistakes
- · Treating the metric as a verdict instead of a screen.
- · Using broker-package assumptions without checking the source documents.
- · Ignoring taxes, capex, vacancy, financing terms, and timing.
Use current local data and source documents. Realist should show assumptions and date-stamp market inputs because stale inputs create fake precision.
