Offering Memorandum Guide for Multifamily Properties
Multifamily investors review dozens of OMs per week. Yours gets maybe two minutes before they decide to dig in or move on. The difference between a deal that gets follow-up calls and one that gets filed away comes down to how you present the rent roll, your T-12, and the value-add story. Generic OM advice doesn't cut it here — apartment deals have their own logic.
Rent Roll Presentation
The rent roll is the first page most multifamily investors flip to. Not the executive summary, not the photos. Get this wrong and nothing else matters.
Show current rent vs market rent for every unit
Investors want three numbers per unit: current rent, market rent, and loss-to-lease. If you only show what tenants are paying today, the investor has to build their own market rent assumptions. Their number will be worse than yours.
Best Practice
Use a third-party rent comp service (CoStar, Yardi Matrix) to support your market rent figures. Include the source in a footnote.
Include lease expiration dates
An investor underwriting a value-add deal needs to know when they can actually push rents. A rent roll without lease terms creates questions instead of answering them.
Best Practice
Add a lease expiration schedule chart showing the percentage of leases expiring by quarter over the next 24 months.
Break out concessions separately
Burying concessions in the effective rent makes the rent roll look misleading. Sophisticated investors will catch it and question everything else in the document.
Best Practice
Show gross rent, concessions, and effective rent as separate columns. Note whether concessions are one-time or recurring.
Flag down units and model units
Down units affect your vacancy calculation and your CapEx story. Hiding them in the rent roll looks like you're inflating occupancy.
Best Practice
Use a status column (occupied, vacant, down, model) and explain why each down unit is offline and when it returns.
Unit mix summary table
Investors want to quickly see how many 1BR, 2BR, 3BR units you have and the average rent per type. Don't make them count units from the full rent roll.
Best Practice
Put the unit mix summary on the same page as the rent roll, or on the facing page. Include average SF, average rent, and average rent per SF for each type.
Financial Presentation — T-12 and Pro Forma
The trailing-12 is where investors do their real underwriting. A clean T-12 with clear line items builds trust. A messy one with vague categories creates doubt.
Present a month-by-month T-12, not just totals
Annualized totals hide trends. Investors want to see if insurance spiked, if vacancy improved, if repairs are climbing. Monthly data tells a story that annual summaries don't.
Best Practice
Show all 12 months plus trailing-12 totals. Bold the total column. Include year-over-year comparison if available.
Break out every expense line item
When you lump expenses into 'other operating expenses: $47,000,' expect a follow-up email asking for the breakout. That email is friction. Enough friction kills deals.
Best Practice
Standard categories: taxes, insurance, utilities, repairs/maintenance, management fee, payroll, marketing, admin, contract services, reserves.
Make your NOI consistent everywhere
The number one mistake in multifamily OMs: the executive summary shows one NOI, the T-12 shows another, and the pro forma implies a third. Pick a number and make it consistent.
Best Practice
Use the trailing-12 NOI as your baseline everywhere. If you reference a 'stabilized' or 'pro forma' NOI, label it clearly and explain the assumptions.
Show per-unit economics
Multifamily investors think in per-unit terms. Revenue per unit, expenses per unit, NOI per unit. If they have to do the division themselves, you're creating work.
Best Practice
Add a per-unit column alongside your actual figures. Include industry benchmarks for comparison where possible.
Include a realistic pro forma
A pro forma that projects 10% rent growth and flat expenses isn't a financial model — it's a wish list. Investors see through aggressive projections immediately.
Best Practice
Show conservative, moderate, and aggressive scenarios. Base rent growth on actual submarket data from CoStar or similar source.
Value-Add Story and Capital Expenditure
Most multifamily deals are marketed as value-add. The OM needs to make the case with numbers, not just promises about 'upside potential.'
Quantify the renovation premium
Don't just say 'renovated units achieve higher rents.' Show exactly what was spent per unit, what rent increase was achieved, and what the ROI looks like. Investors need to model this.
Best Practice
Include a renovated vs unrenovated comparison table: CapEx per unit, pre/post renovation rent, rent premium, and return on cost.
Detail the renovation scope and timeline
What does a renovation actually include? Countertops? Fixtures? Flooring? Full kitchen replacement? The cost difference between a cosmetic refresh and a gut renovation is 3-5x.
Best Practice
List specific renovation items with costs. Include photos of completed renovations alongside the scope of work.
Show how many units are left to renovate
The value-add thesis is only as strong as the remaining opportunity. If 80% of units are already renovated, the upside story is mostly priced in.
Best Practice
Break out the portfolio: renovated units, partially renovated, and unrenovated. Show the remaining capital budget and projected rent premium.
Include common area and exterior improvements
Unit renovations get all the attention, but common area upgrades (lobby, fitness center, pool, landscaping) drive retention and justify rent increases.
Best Practice
Separate interior CapEx from exterior/common area CapEx. Show which improvements are already completed and which are planned.
Market Context and Comparables
Your property doesn't exist in a vacuum. Investors underwrite the submarket as much as the building. Give them the data to do that without leaving your document.
Comparable sales with per-unit pricing
Multifamily comp sets should show price per unit, cap rate, year built, and unit count. Price per SF is less useful here than in office or retail — investors think per-unit.
Best Practice
Include 5-8 recent sales (within 18 months) in the submarket. Show adjustments for vintage, condition, and amenity differences.
Rent comparables with unit-level detail
Which competing properties offer similar units at what rents? This validates your market rent assumptions more than any third-party data source.
Best Practice
Show 4-6 rent comps with unit type, SF, asking rent, rent per SF, and concessions. Include property quality ratings for context.
Supply pipeline data
How many new units are being built within a 3-mile radius? This is the question every investor asks, and if you don't answer it, they'll assume the worst.
Best Practice
Map of planned, under construction, and recently delivered projects within 3 miles. Include unit counts and expected delivery dates.
Submarket employment and population data
Apartment demand is driven by job growth and population growth. Include the data that supports (or at least contextualizes) rent growth projections.
Best Practice
One page with key submarket metrics: population growth rate, job growth rate, major employers, median household income, and renter percentage.
Walk Score and transportation access
Walkability and transit scores directly affect rent premiums in most metros. Investors factor this into their underwriting whether you present it or not.
Best Practice
Include Walk Score, Transit Score, and Bike Score. Add a map showing proximity to transit, grocery, employment centers.
Deal Structure and Presentation
Even a great property loses deals on presentation. The mechanics of how you structure the OM affect whether investors take it seriously.
Lead with the investment thesis, not the property description
Nobody reads OMs to learn about the building. They read them to evaluate an investment. Open with why this is a compelling opportunity — the numbers, the story, the timing.
Best Practice
Executive summary should cover: asking price, in-place cap rate, value-add cap rate, price per unit vs comps, and the 30-second thesis.
Use professional photography
Phone photos signal that you're not serious. Professional photography costs $500-$1,000 and the difference in perceived quality is enormous.
Best Practice
Exterior photos in good lighting (golden hour), interior photos of best units and common areas, aerial/drone shot for larger communities.
Include a property condition assessment summary
Investors want to know what CapEx they're inheriting. A brief condition assessment of roof, HVAC, plumbing, and electrical saves them the guesswork.
Best Practice
One-page table showing each major system, approximate age, estimated remaining useful life, and estimated replacement cost.
Add a clear call-to-action and timeline
What happens after they read this? When are offers due? What's the process? Don't assume they know — spell it out.
Best Practice
Include offer deadline, tour availability, required deposit amount, and preferred financing terms. Name a specific contact person.
Common OM Mistakes
NOI inconsistency between executive summary and T-12
Impact: Instantly destroys credibility. Investors wonder what else is wrong with the numbers.
Fix: Use one consistent trailing-12 NOI figure everywhere. If referencing pro forma NOI, always label it 'Pro Forma' or 'Stabilized.'
Missing loss-to-lease analysis
Impact: Investors can't assess the upside without seeing the gap between in-place rents and market rents.
Fix: Add a column to the rent roll showing market rent and loss-to-lease per unit. Summarize total portfolio loss-to-lease in the executive summary.
Aggressive pro forma with no basis
Impact: Projecting 8% annual rent growth with 'conservative' in the title doesn't fool anyone. It makes the broker look detached from reality.
Fix: Base rent growth on actual submarket trends over the past 3-5 years. Show the data source.
No supply pipeline disclosure
Impact: If there are 2,000 units under construction in the submarket and you don't mention it, the investor finds out on their own and questions your candor.
Fix: Include a new supply map and table. Address the supply with context — absorption rates, submarket vacancy trends, demand drivers.
Using price per SF instead of price per unit
Impact: Multifamily investors think in per-unit terms. Leading with price per SF suggests you don't know the buyer audience.
Fix: Lead with price per unit in all summary metrics. Include price per SF as a secondary data point.
Key Metrics for Multifamily OMs
| Metric | What It Tells Investors | Typical Range | Data Source |
|---|---|---|---|
| Price Per Unit | Primary valuation benchmark for multifamily. Investors immediately compare to recent trades. | $75,000-$500,000+ depending on market, vintage, and condition | CoStar, Real Capital Analytics, recent sales comps |
| In-Place Cap Rate | Current yield based on trailing NOI and asking price. The single most-referenced number in the OM. | 4.0%-7.0% in most markets, varies by quality and location | Calculated: T-12 NOI / Asking Price |
| Pro Forma Cap Rate | Projected yield after value-add execution. Shows the spread between in-place and stabilized returns. | 50-150 basis points above in-place cap rate for value-add deals | Calculated from pro forma NOI with clearly stated assumptions |
| Occupancy Rate | Current physical occupancy. Below 90% raises questions. Above 97% suggests limited organic rent growth. | 92%-97% for stabilized assets | Current rent roll, verified against the trailing 12 months |
| Loss-to-Lease | Gap between in-place rents and market rents. Directly quantifies the organic upside without capital investment. | 5%-15% for value-add opportunities | Rent roll (in-place) vs rent comp survey or third-party data (CoStar, Yardi Matrix) |
| Expense Ratio | Operating expenses as a percentage of effective gross income. High ratios suggest inefficiency or deferred maintenance. | 40%-55% for most multifamily | T-12 operating statement |
