Condominium
Condominium, Co-op, Townhouse, Duplex, Triplex, and Fourplex
Quick Definition
These terms describe distinct types of residential properties that differ in ownership structure, financing, legal rights, and investment characteristics. Understanding the differences is essential before buying, renting, or investing in any of them.
Condominium (Condo)
What It Is
A condominium is a form of property ownership where you own your individual unit outright (as real property) plus a proportional share of common areas like hallways, lobbies, pools, and parking. A Homeowners Association (HOA) governs the common areas and enforces community rules.
Ownership Structure
- You hold fee simple title to the interior of your unit
- Common areas are jointly owned by all unit owners
- HOA manages and maintains common areas; you pay monthly HOA fees
Financing
Condos are financed with regular mortgages, but lenders scrutinize the entire condo development:
- At least 50% of units must be owner-occupied (for conventional loans)
- The HOA must be financially healthy with adequate reserves
- No single entity can own more than 10% of all units
- FHA approval needed for FHA loans (many condos are not FHA-approved)
Pros and Cons
| Pros | Cons |
|---|---|
| Lower purchase price than single-family | Monthly HOA fees (can be $200-$1,000+) |
| Low maintenance (exterior handled by HOA) | HOA rules restrict modifications, rentals |
| Amenities (gym, pool, concierge) | Special assessments for major repairs |
| Urban locations often available | Less privacy than single-family |
Co-op (Housing Cooperative)
What It Is
In a co-op, you do not own your unit at all. Instead, you buy shares in a corporation that owns the entire building. Your shares entitle you to a proprietary lease for your unit. Co-ops are most common in New York City, where they account for ~75% of available apartments for sale.
Ownership Structure
- You own shares in the co-op corporation (personal property, not real property)
- The corporation owns the building and holds the underlying mortgage
- A board of directors governs the co-op and approves all purchases and sublets
Key Differences from a Condo
| Feature | Condo | Co-op |
|---|---|---|
| What you own | Real property (title to unit) | Personal property (shares in corporation) |
| Board approval | Not required (usually) | Required; board can reject buyers |
| Financing | Mortgage (real estate loan) | Share loan (personal property loan) |
| Monthly fees | HOA fee | Maintenance fee (includes share of building mortgage) |
| Sublet rules | Often flexible | Often restrictive |
| Down payment | 10-20% typical | Often 20-30%+ required |
Co-op Board Approval
Co-op boards are notoriously selective. The application process typically includes:
- Detailed financial disclosures (tax returns, bank statements, net worth)
- Board interview
- Reference letters from neighbors and employers
- Some boards require all-cash purchases
Pros and Cons
| Pros | Cons |
|---|---|
| Often cheaper than equivalent condo | Board can reject you for any reason |
| Strong community; neighbors vetted | Hard to sublease (often prohibited) |
| Board protects quality of residents | Harder to finance (share loans) |
| Underlying mortgage creates leverage | Lower liquidity (smaller buyer pool) |
Townhouse
What It Is
A townhouse is a multi-story home that shares one or two walls with adjacent units. The key distinction from a condo: you typically own the land under your unit and the airspace above it. Townhouses can be owned as condos (with an HOA owning common areas) or as fee-simple properties.
Ownership Structure
- Usually fee simple ownership including the land parcel
- May or may not have an HOA depending on the development
- More similar to a single-family home than a condo in terms of ownership rights
Pros and Cons
| Pros | Cons |
|---|---|
| More space than a condo (usually) | Shared walls mean some noise |
| Private entrance; no hallways | Multiple stairs (not always accessible) |
| Often includes private outdoor space | May have HOA with fees and restrictions |
| More affordable than detached single-family | Less privacy than fully detached home |
Duplex, Triplex, and Fourplex
These are small multifamily properties containing 2, 3, or 4 residential units respectively under one roof.
What They Are
| Property | Units | Classification |
|---|---|---|
| Duplex | 2 units | Residential (1-4 units = residential financing) |
| Triplex | 3 units | Residential |
| Fourplex | 4 units | Residential (barely; 5+ units = commercial) |
| 5+ unit | 5+ | Commercial real estate (different financing) |
The 4-unit cutoff is critically important: properties with 1-4 units qualify for conventional residential mortgages (Fannie Mae/Freddie Mac), FHA loans, and VA loans. Five units and above require commercial financing with typically higher rates, shorter terms, and stricter underwriting.
The House Hacking Strategy
Duplexes, triplexes, and fourplexes are the classic "house hacking" property -- where the owner lives in one unit and rents the others:
Example: Fourplex House Hack
- Purchase price: $600,000
- FHA loan: 3.5% down = $21,000 down payment
- Monthly PITI (principal, interest, taxes, insurance): $4,200
- Three rental units renting at $1,200 each: $3,600 monthly income
- Net monthly housing cost: $600 (vs. $4,200 to live alone)
This strategy lets owner-occupants reduce or eliminate their housing costs while building equity, using owner-occupant financing (lower rates, lower down payments) rather than investment property financing.
Pros and Cons of Small Multifamily
| Pros | Cons |
|---|---|
| Residential financing (lower rates, 3.5-20% down) | Owner may live next to tenants (limited privacy) |
| House hacking reduces housing cost | Tenant turnover and management responsibilities |
| 3 income streams in a fourplex | Local landlord-tenant laws apply |
| Single building, concentrated management | Harder to diversify risk than across properties |
| Builds rental income and equity simultaneously | Vacancy affects larger portion of income than large building |
Quick Comparison Table
| Property Type | Own Land? | HOA? | Residential Financing? | Best For |
|---|---|---|---|---|
| Condo | No | Yes | Yes (with restrictions) | Urban buyers, low-maintenance lifestyle |
| Co-op | No | Board | Share loans | New York City; community-focused buyers |
| Townhouse | Usually | Sometimes | Yes | More space than condo, less than single-family |
| Duplex | Yes | Rarely | Yes (1-4 units) | House hackers, small-scale landlords |
| Triplex | Yes | Rarely | Yes | Higher rental income; still residential financing |
| Fourplex | Yes | Rarely | Yes (max for residential) | Maximum residential financing advantage |
Key Points to Remember
- A condo gives you title to your unit; a co-op gives you shares in a corporation that owns the building
- Co-op board approval can be rejected for any reason, making co-ops harder to buy and sell than condos
- Townhouses typically include land ownership, making them more similar to single-family homes than condos
- Properties with 4 or fewer units qualify for residential financing (lower rates, lower down payments)
- House hacking a duplex/triplex/fourplex using FHA financing is one of the most proven wealth-building strategies for first-time investors
Frequently Asked Questions
Q: Is a condo or co-op a better investment? A: Condos are generally more liquid and have fewer restrictions on buyers and subtenants, making them more investment-friendly. Co-ops can be bought at lower prices but have a smaller pool of eligible buyers, which can suppress appreciation and make them harder to sell.
Q: Can I get an FHA loan for a fourplex? A: Yes, if you plan to live in one of the units. FHA loans on 2-4 unit properties require owner occupancy. Down payment is 3.5% (with 580+ credit score). This makes FHA the most accessible path to buying an income-producing property.
Q: Are HOA fees worth it? A: It depends on what they cover. HOA fees that include exterior maintenance, water/sewer, and amenities (gym, pool, doorman) can represent real value. HOA fees that only cover basic landscaping and cost $400/month are harder to justify. Always get 3 years of HOA financial statements before buying to assess reserve adequacy.
Q: What happens if a co-op corporation goes bankrupt? A: This is a real risk unique to co-ops. If the co-op corporation cannot pay its underlying mortgage, the lender could foreclose on the building, wiping out all shareholders. This is extremely rare with established co-ops but underscores why co-op financial health must be scrutinized carefully.
