How to Wholesale Multi-Family Properties (2-4 Units)

Why Multi-Family Wholesaling Is Different

Most wholesalers focus on single-family homes — which means multi-family deals (duplexes, triplexes, fourplexes) are less picked over, less competitive, and often deliver larger assignment fees. But they require a different analysis framework. Your buyers are evaluating cash flow and cap rate, not just ARV. This guide covers everything you need to successfully wholesale 2-4 unit properties.

The Multi-Family Advantage for Wholesalers

Less Competition

Most wholesalers chase single-family homes. The 2-4 unit space has far fewer active buyers hunting off-market deals, which means better pricing from sellers.

Larger Spreads

Multi-family properties command higher prices than single-family — which means larger absolute dollar spreads and bigger assignment fees even at the same percentage margin.

Active Buyer Pool

Landlords, buy-and-hold investors, and BRRRR players actively seek 2-4 unit deals. A strong multi-family deal with real cash flow numbers moves fast.

Motivated Sellers Exist

Tired landlords with problem tenants, estate situations, deferred maintenance — the same seller motivations that drive single-family deals exist in multi-family, and sometimes more acutely.

How Multi-Family Analysis Differs From Single-Family

In single-family wholesaling, your buyers primarily care about ARV and rehab cost. In multi-family, they care equally (often more) about cash flow metrics.

The Metrics That Matter for 2-4 Unit Buyers:

Gross Rent Multiplier (GRM)

GRM = Purchase Price / Annual Gross Rent

Lower GRM = better deal. Buyers target GRM of 7-10 in most markets.

Capitalization Rate (Cap Rate)

Cap Rate = Net Operating Income / Purchase Price

NOI = Gross Rent - Vacancy (5-10%) - Expenses (taxes, insurance, maintenance, management)

Target cap rate varies by market: 6-8% is common in secondary markets, 4-5% in major metros.

Cash-on-Cash Return

Cash-on-Cash = Annual Cash Flow / Total Cash Invested

Buyers using financing care about cash-on-cash. Target: 8%+ for most investors.

When analyzing multi-family deals, gather current rent rolls (actual rents being collected) AND market rents (what units could rent for). The spread between the two is often where the opportunity lives.

Finding Multi-Family Motivated Sellers

The same outreach methods that work for single-family also work here — but you add a few multi-family-specific sources:

Direct Mail Targeting:

Absentee owners of 2-4 unit properties (out-of-state landlords)
Properties with code violations (often sign of tired landlord)
Properties with delinquent property taxes
Owners who have held the property 10+ years (often over-leveraged or done managing)

Driving for Dollars:

Look for deferred maintenance: peeling paint, overgrown landscaping, boarded windows, broken railings
Multi-family problems are usually more visible than single-family

Probate and Estate:

Inherited multi-family is often a headache for heirs who don't want to be landlords
Probate filings (public record) reveal multi-family estates frequently

Direct Outreach to Landlords:

Skip trace owners of rental properties via county records
Call Craigslist "For Rent" ads for multi-family ("I work with investors who buy rental properties...")

What Your Buyers Need to See

Multi-family buyers are more analytical than single-family flippers. Come to every conversation with:

Current rent roll — what each unit currently rents for
Market rents — what each unit could rent for at full market rate
Vacancy status — which units are occupied, which are vacant
Expense estimates — property taxes, insurance, maintenance
Your purchase price — and why the numbers work at that price
Rehab estimate — condition of units, major systems (roof, HVAC, plumbing)

For buy-and-hold buyers, a one-page deal summary with current income, projected income, expenses, NOI, and cap rate at your contract price is extremely effective. Build this template once and reuse it.

Evaluating the Deal: A Worked Example

Property: Duplex, 2 units each renting at $800/month (below market — market is $1,050) Your Contract Price: $120,000 Rehab Needed: $20,000 (cosmetic updates to vacant unit, deferred maintenance) Your End Buyer's Price: $145,000 (your assignment fee: $25,000)

At $145,000:

Gross monthly rent (market): $2,100/month
Annual gross rent: $25,200
GRM = $145,000 / $25,200 = 5.8 (excellent)
Annual NOI (after 45% expenses): $13,860
Cap Rate = $13,860 / $145,000 = 9.6% (strong)

This deal pencils out well for a buy-and-hold investor in most markets.

Never present pro forma numbers (projected rents) as if they're current rents without being explicit. Buyers who close on inflated projections will never buy from you again. Always label what is current vs projected.

Common Mistakes in Multi-Family Wholesaling

Underestimating rehab: Multi-family rehab costs compound — if one unit needs a new HVAC, the others often follow soon. Be conservative with estimates.

Ignoring tenant situation: A tenant who won't leave is a problem your buyer inherits. Know the lease terms, security deposits, and any tenant disputes before marketing the deal.

Wrong buyer type: Multi-family deals need buy-and-hold buyers, not fix-and-flip buyers. Know your buyers' preferences and market deals to the right people.

Not knowing zoning: Verify the property is legally permitted for its current use. Illegal conversions exist — especially in older cities where basements or garages have been turned into units.

Structuring the Wholesale Deal

The same assignment and double-close mechanics from single-family apply to multi-family:

Include "and/or assigns" in your purchase contract
Collect non-refundable earnest money from your buyer
Use an investor-friendly title company familiar with multi-family transactions
Get your assignment fee in the $15,000-$40,000 range on 2-4 unit deals (justified by deal size)
