Free templates for the board
Two spreadsheets most housing co-op boards keep: who holds each share, and who is waiting for a home.
Share ledger
One row per share certificate: who holds it, what they paid, when the board approved it, and the formula price when it changed hands.
Columns: Unit · Shareholder name(s) · Number of shares · Share certificate number · Date issued · Price paid · Board approval date · Date transferred or surrendered · Resale formula price at transfer · Notes
Waitlist
One row per applicant household, in the order applications arrived, with the income check and every offer made.
Columns: Position · Applicant name(s) · Date application received · Household size · Unit size wanted · Income checked on (date) · Status (waiting / offered / declined / housed / withdrawn) · Date offered · Unit offered · Notes
Keeping the ledger and waitlist for the whole co-op?
We are testing interest in a share and waitlist ledger for housing co-op boards:
- Every share certificate, holder and transfer in one place
- The waitlist in order, with income checks and every offer recorded
- The resale formula price worked out for each sale
- A board report for each transfer you approve
Tell us about your co-op if your board would use it.
How resale formulas work
In a limited-equity co-op, a member who sells gets back what they paid plus a set amount of growth, not the market price. That keeps homes affordable for the next household. There is no single national formula: each co-op's bylaws, regulatory agreement or covenant sets its own. The common shapes are:
A fixed yearly rate
The share price grows by a set percentage each year, either compounded or as simple interest. Check which one your bylaws use: on a $10,000 share held ten years at 2%, compounding gives $12,189.94 and simple growth $12,000.
An index
The price moves with an index such as the Consumer Price Index or the area median income. Some formulas use whichever is lower, and hold each year's change between a floor and a cap.
Improvements and money owed
Many formulas add the cost of improvements the board approved, sometimes reduced over the improvement's useful life, and take off unpaid charges or repairs the seller owes.
