The question
Does building a unit pay for itself, and how would I fund it?
Construction cost against added income and added value.
What we know
Pulled from My Stuff. Nothing is re-asked.
Nothing on file yet that bears on this decision. You can still work it through here — or add a few things in My Stuff so every future decision starts warmer.
What we still need
Only the things that genuinely move the answer. Approximate is fine — leave anything blank and it stays a stated assumption, never an invented number.
Stated assumptions
- Assuming no builder estimate — cost overruns of 10-20% are common.
- Assuming rent it could bring not provided.
- Assuming how you'd pay for it not provided.
- Assuming local rules you've checked not provided.
CredABLE won't turn these into an authoritative-looking figure. Where a number decides the answer, it will say so and ask.
Options
Real alternatives. Very few of these decisions are actually yes or no.
Build it, funded by equity
Cheapest money if the rent covers the added payment.
Build a smaller version
Conversion or garage unit instead of new construction.
Rent existing space instead
No construction risk at all.
Don't build yet
If rules are unclear or cash is thin.
Impact
What CredABLE will compare the options on.
What changes the answer
Assumptions that can flip the recommendation, stated up front.
- Local rules. Confirm zoning and permitting before anything else.
- Whether the rent covers the added payment during the build, when there is no rent.
- Actual bids versus estimates.
CredABLE's take
A clear read on your version of this, plus the next move.
You'll get one interpretation, not a shrug — and every assumption behind a number will be written in front of it.
