Level 12 — The Vacant Lot $180,000 · corner lot

You have $180,000 and a corner lot. Two tenants are interested. Pick a build and see what the rent does after the loan is paid.

One retail unit Single tenant, full lot Two small units Two tenants, split the lot Hold the lot Build nothing, wait
Build cost $178,000
Rent $2,400/mo
Loan payment $1,745/mo
Margin +$415/mo

Two tenants pay more than one, and if either leaves the other still covers most of the loan. That second door is what you were buying.

Best solution · Level 13 unlocked Try it. You can undo any move.

How a level teaches

The game never explains a term before you have met it. You make the move, watch the number change, and the name arrives afterwards, attached to something you already did.

Step 01 The brief Two sentences and a number. What you have, what is on offer, and nothing you do not need yet.
Step 02 The move Place the build, pick the tenant, set the loan. No penalty for a wrong turn and no timer running.
Step 03 The number Rent, payment and what is left. The figure moves in front of you so the cause is never in doubt.
Step 04 The name Only now does the game call it margin, or leverage, or vacancy — attached to a thing you just watched happen.

Three kinds of puzzle

Each set runs on the same board and asks a different question of it. A level is short enough to finish standing up and hard enough to be worth finishing.

Build
40 levels

Fit the structure to the lot. Setbacks, access, unit count and what the ground will carry, solved by placement rather than arithmetic.

Teaches: site constraints, unit mix, buildable area

Finance
36 levels

The building is decided; the money is not. Choose the loan, the term and the deposit, and watch which combination survives a bad month.

Teaches: leverage, amortisation, debt service cover

Hold
28 levels

You already own it. Rent reviews, a vacancy, a roof that needs replacing — decide what to spend and what to sit on.

Teaches: capital expenditure, vacancy, timing

Nothing to lose

Every move can be undone, every level replayed, and a wrong answer costs nothing but the try. The point is to see what the numbers do, and that only works if experimenting is free.
