What Do You Need to Start a Rental Property?
You need roughly $420,000 in owner equity to acquire an eight-unit residential building priced at $1,350,000, with a $945,000 mortgage at 7% over 30 years. Revenue Map's rental property presets model $1,550 per unit per month at 88% occupancy in the launch phase, producing about $10,900 of monthly collected rent against roughly $2,550 of operating costs plus mortgage debt service.
Rental property requires three things that cost real money before any rent arrives: a building, financing, and enough cash reserve to cover vacancies and maintenance during the first year. Revenue Map's presets model the default as a small multifamily building bought with tenants in place, so there is no build-out, but there is a down payment that runs roughly 30% of purchase price plus closing costs. The deliberate omission in the model is appreciation: it asks only whether the building pays for itself out of rent, which is the part you control.
Format changes the numbers completely. Single-family rentals preset at four units and $2,100 per month rent with a $1,250,000 purchase price. Short-term rentals run $3,200 per night-equivalent at 62% occupancy but carry higher admin costs. Mixed-use buildings preset at ten units, $1,750 per month, and a $1,650,000 purchase. The checklist below covers what every format needs, anchored to the default eight-unit small multifamily preset.
Cost Breakdown
What you need to start a rental property and what it costs
| Item | Typical range | Notes | Source |
|---|---|---|---|
| Building acquisition | $1,150,000 to $1,650,000 | Default small multifamily $1,350,000; single-family portfolio $1,250,000; mixed-use $1,650,000 | Revenue Map model presets |
| Owner equity (down payment plus closing) | About $420,000 | Roughly 30% of purchase price; lenders finance the balance at around 70% loan-to-cost | Revenue Map model presets |
| Mortgage financing (default) | $945,000 at 7% over 30 years | Covers 70% of the $1,350,000 default purchase; amortized against the real estate | Revenue Map model presets |
| Monthly operating costs | About $2,550 | Utilities $450, insurance $750, property management $1,100, marketing $250; no staff on a small building | Revenue Map model presets |
| Monthly rental income (context) | About $10,900 at launch | Eight units at 88% occupancy at $1,550 per month; rising to $12,920 at 95% occupancy and $1,700 rent | Revenue Map model presets |
| Depreciation (tax context) | 27.5 years straight-line | US tax code schedule for residential rental property; one of the few figures that is a public rule | Revenue Map model templates |

What Moves the Number
Format sets the purchase price and the cash flow shape
A single-family rental portfolio presets at four units and $2,100 per month with a $1,250,000 purchase, while a mixed-use building carries ten units at $1,750 and a $1,650,000 purchase. Short-term rentals preset at $3,200 per night-equivalent but only 62% occupancy and higher admin at $2,400 per month. The format choice locks in the purchase price, the rent ceiling, and the vacancy pattern.
Occupancy is the variable that decides yield
Revenue Map's presets ramp occupancy from 88% at launch to 94% in the growth phase and 95% at maturity. The difference between 88% and 95% on eight units at $1,550 is roughly $820 of monthly rent, which flows almost entirely to the bottom line because operating costs are fixed. Vacancy, not rent level, is the primary driver of rental yield.
Cash flow must cover debt service, not just operating costs
Lenders screen on a debt service coverage ratio of at least 1.25, meaning net operating income must exceed mortgage payments by 25%. Revenue Map's presets build this test in. A building that clears operating costs but not the loan payment is not investable, and the owner's equity return depends on the spread between collected rent and total obligations.
Maintenance reserves are what protect the yield
Revenue Map's presets carry property management at about 8% of collected rent through the admin line. On top of that, unreserved maintenance is what turns a positive yield negative. Industry practice funds 5 to 10% of annual rent into a maintenance reserve, and the model structure accounts for this as part of the operating base rather than treating it as a surprise.
