Small Multifamily (5-20 Units) vs Large Apartment Syndications
On this page
A small multifamily building (5 to 20 units) needs less equity and a smaller team, but each vacant unit takes a bigger share of income. A large complex spreads vacancy across many units and often attracts professional managers, but it needs more capital, more investors and more experience. Neither is better in general. Choose the size that matches your market, your team and how much money your friends and followers can reasonably put in.
This post builds on how many units a deal should have. Rules are as of October 2026.
How is a small building different?
With 8 units, one vacancy is a big slice of income. A single roof or boiler problem can affect cash flow for the year. On the other hand, you may need less equity, so a smaller group of investors can fund it, and the property can be easier to understand. Many small buildings are managed by a local company or a single person, so reporting quality varies. DoorRaise works with apartment buildings with 5 or more units.
How is a large complex different?
Spread across 150 units, one vacancy matters less, and an on-site team and professional manager are normal. But the purchase price is larger, so you need more equity, more investors and often an experienced co-sponsor or key principal. Lenders also look harder at the sponsor team's track record on bigger loans; see loan guarantors.
What about the loan?
Loan programs vary by size and by lender. Smaller properties may fit programs described in Fannie Mae small balance loans, while larger ones use other agency, bank or bridge options; compare them in bridge vs agency loans. Ask lenders directly what they require, because terms change.
How do I decide?
- Count your realistic equity. Ask how many people have said they are interested and how much each might invest. Do not assume everyone follows through.
- List your team. Who will manage, who will help with the loan, who has run a building this size?
- Check the market. Are there buildings of that size for sale near you? See choosing a market.
- Stress test the numbers. Remove 10 percent of income and see whether the deal still pays its debt; see break-even occupancy.
- Think about the exit. Who buys a building this size when you sell?
What does a downside look like?
On a small building, two vacancies and a major repair in the same year can erase distributions. On a large one, a rate increase or a failed renovation plan can do the same. In both cases, investors can lose money. Show that risk in your materials.
How DoorRaise fits in
DoorRaise runs the same process for any building with 5 or more units: LLC formation, offering documents, escrow at Enterprise Bank & Trust, wire-only funding under Reg D and the investor portal. It charges $1,500 to set up (due when you submit the deal, non-refundable), then $5,000 a year from closing (only if the deal closes). See the deal page.
FAQ
Is a 12-unit building a good place to start?
It can be, if the numbers hold and you have the team. Size does not guarantee safety.
Can I raise money for a small building?
Yes, if you follow the rules for your exemption. See 506(b) vs 506(c).
Do small buildings have professional managers?
Sometimes. Interview them; see choosing a property manager.
Does a larger deal mean larger returns?
No. Size does not decide returns, and no outcome is guaranteed.
