Profit First works because it flips the formula: instead of Sales − Expenses = Profit, you take Sales − Profit = Expenses. For a service business, that is a clean swap. For a rental portfolio, it is not — because a large share of the money hitting your account was never yours to spend.
Security deposits belong to tenants. Property tax and insurance escrow belongs to the county and the carrier. The next HVAC system belongs to a unit that has not failed yet. If you run standard Profit First percentages over gross rent, you will pay yourself out of somebody else's money and discover it during a turnover.
Here is the version of the framework I implement with investors — adapted for doors, deposits, and capital expenditures.
The bank account stack
Six accounts, per entity. Allocations run twice a month — the 10th and the 25th — from collected rent only.
| Account | Target | What it holds |
|---|---|---|
| Income (Property Operating) | 100% in, 0% held | Every rent payment, application fee, and pet fee lands here first. Nothing is spent from this account — it exists only to be allocated. |
| Security Deposits (Trust) | Held in full | Not revenue. Not reserves. In most states it is the tenant's money you are holding, and in several it must sit in a separate account. Treat it as untouchable. |
| Real Estate Taxes | Actual escrow need | Property taxes, insurance premiums, and your own income tax set-aside. Fund it monthly, not in December. |
| CapEx Reserve | 5–15% of rent | Roofs, HVAC, water heaters, turnovers. Size it from the remaining useful life of the actual components, not a rule of thumb. |
| Operating Expenses | Balance after allocations | Property management fees, maintenance, utilities, HOA, marketing, software, debt service. |
| Profit | 5% and climbing | Distributed quarterly. This is the account that turns a portfolio into wealth instead of a second job. |
Sizing the CapEx reserve per door
Percentage rules of thumb are a starting point, not an answer. Build the number from the assets you actually own: list each major component, its replacement cost, and its remaining useful life. Divide cost by remaining years, then by twelve.
A roof with a $12,000 replacement cost and 8 years of life left needs $125/month. Add the HVAC, water heater, flooring, and appliances, and you have a defensible monthly CapEx allocation for that door — usually somewhere between 5% and 15% of rent, and far higher on older stock than a blanket 5% would ever suggest.
Run this once per property, revisit it annually, and your reserve stops being a guess. It also gives your lender and your insurer a story that holds up.
Five mistakes that break the system
01
Counting deposits as cash
A portfolio that looks liquid because of $38,000 in held deposits is not liquid. Move deposits out of the operating account on day one and reconcile them per unit.
02
Treating CapEx as an expense surprise
A roof is not an emergency; it is a scheduled event with an unknown date. Reserve for it monthly per door so the replacement is a withdrawal, not a loan.
03
Allocating on gross rent instead of collected rent
Allocate from money actually received. Vacancy, concessions, and delinquency should shrink allocations automatically — that is the point.
04
Netting property management fees
When your manager remits rent net of fees and repairs, the gross and the deductions both need to hit the books. Netting hides expense creep and understates deductible expenses at tax time.
05
Commingling entities
One bank stack per entity. If three LLCs share an account, your liability protection, your lender package, and your K-1s all get harder than they need to be.
Where tax strategy meets the allocation
Allocation discipline and tax strategy are the same conversation. A cost segregation study can accelerate depreciation on a property and change what you owe this year — which changes what your tax account needs to hold. Repairs versus improvements determines whether a $9,000 expenditure is deductible now or capitalized over decades, which changes both your CapEx draw and your return.
The investors who compound are the ones who decide these things in Q3 with a plan, not in April with a shoebox. That is the difference between a bookkeeper and a CFO seat.
Your first 30 days
- Open the six accounts for your primary entity.
- Move every security deposit out of operating and reconcile the balance per unit against your leases.
- Build the CapEx schedule for each door and set the monthly reserve figure.
- Set two allocation days per month and run them from collected rent.
- Take your first Profit distribution at the end of the quarter — however small. The habit matters more than the amount.
