Wholesaling Triplexes and Fourplexes

Triplexes and fourplexes occupy the highest value niche in residential real estate investing. They are the largest properties you can buy with conventional residential financing, including FHA loans with just 3.5% down. For wholesalers, that means the buyer pool includes everyone from first-time house-hackers to seasoned portfolio landlords. And because most wholesalers focus exclusively on single-family, the competition for these deals is significantly lower.

Why 3-4 unit properties are the sweet spot

The magic number in real estate financing is four. Properties with one to four units qualify for residential loans: Fannie Mae, Freddie Mac, FHA, and VA. Once you hit five units, the property is classified as commercial, which means commercial underwriting, higher down payments (typically 25%), higher interest rates, and fewer lenders willing to make the loan.

This four-unit ceiling creates a natural demand concentration. Investors who want multi-family income without commercial complexity are all competing for the same inventory of 2-4 unit buildings. That demand pressure means well-priced triplexes and fourplexes move fast, which is exactly what you want as a wholesaler.

Consider the economics from the buyer's perspective. A fourplex with four units renting at $1,000/month generates $48,000 in annual gross rent. Even at a conservative 50% expense ratio, that is $24,000 in net operating income. For a house-hacker living in one unit, three units at $1,000/month ($36,000/year) can cover most or all of the mortgage payment on a property worth $300,000-$400,000.

Valuation: income approach dominates

While duplexes can be valued using both sales comps and income analysis, triplexes and fourplexes lean heavily toward the income approach. Sales comps for 3-4 unit buildings are scarce in most markets. You might find only one or two comparable sales within a reasonable radius over the past year. That makes the income approach the primary valuation tool.

Cap rate analysis

Market cap rates for small multi-family vary by location, condition, and tenant quality. In strong urban markets, you might see cap rates of 5-6%. In secondary and tertiary markets, 7-10% cap rates are common. Your job as a wholesaler is to know the prevailing cap rate in your market so you can price the deal accurately.

Use cap rate calculators and cash flow analysis tools to model these scenarios quickly. Present the income analysis alongside any sales comps you can find to give your buyers a complete picture.

Gross rent multiplier

The GRM is a quicker, rougher valuation tool. It divides the sale price by the annual gross rent. In most markets, small multi-family properties trade at GRMs between 6 and 12. A fourplex generating $48,000/year at a GRM of 8 would be valued around $384,000. GRM is useful for quick screening but should be backed up by full NOI analysis for your marketing package.

Finding triplex and fourplex deals

These properties require targeted lead generation. Generic direct mail campaigns that target all homeowners will mostly hit single-family owners. You need to filter specifically for multi-family property types in your data sources.

• County assessor records: Filter for property type codes that indicate 3-4 unit residential. Each county uses different codes, so check your local assessor's classification system.
• Absentee owner lists: Absentee owners of multi-family properties are often the most motivated. They are managing tenants from a distance, dealing with maintenance calls, and may have inherited a building they never wanted to manage.
• Tired landlord indicators: Look for owners who have held the property for 10+ years, have deferred maintenance (visible from driving by), or have had frequent tenant turnover (indicated by multiple listed rents on rental sites).
• Tax delinquency: Multi-family properties with delinquent taxes often indicate an owner who is upside down on the investment and ready to sell at a discount.
• Code violations: Properties with open building code violations are under pressure from the city. The owner may prefer selling to fixing, especially if the violations require significant capital.

Analyzing the deal

Your property analysis for a triplex or fourplex must cover more ground than a single-family deal. Here is the checklist:

Rent roll verification

Get the current rent roll from the seller. Verify it against market rents using rental comps. If the current rents are significantly below market, that is actually a selling point for buyers because it represents upside. If the rents are at or above market, the buyer has no room to increase income and the property must pencil at current numbers.

Expense analysis

Request the owner's actual operating expenses: taxes, insurance, utilities (if owner-paid), maintenance history, and property management costs. If the owner self-manages, add a 8-10% property management fee to the expense calculation because most buyers will either hire management or value their time at that rate.

Unit-by-unit condition assessment

Each unit needs its own repair estimate. One unit might be recently updated while another needs a full gut renovation. Your marketing package should break down the rehab cost per unit so the buyer can plan phased improvements and stagger renovations around lease expirations.

Capital expenditure reserves

Multi-family properties have shared systems that are expensive to replace: roof, foundation, main sewer line, shared HVAC, parking lot, and common areas. Build a CapEx reserve estimate into your analysis. A standard rule of thumb is $200-$300 per unit per year for CapEx reserves on top of regular operating expenses.

Pricing your assignment fee

Assignment fees on multi-family deals are typically higher than single-family because the transaction values are higher. A $5,000-$15,000 assignment fee on a $300,000 fourplex is reasonable and expected by experienced multi-family buyers. However, the fee must still leave enough margin for your buyer.

Use the income approach to work backward from the buyer's target return. If a landlord buyer wants a 8% cap rate and the NOI is $25,000, the maximum they will pay is $312,500. Subtract your rehab estimate and your assignment fee, and whatever remains is your maximum offer to the seller.

Marketing to multi-family buyers

Your marketing package for a triplex or fourplex should include elements that single-family packages do not:

• Complete rent roll with current rents, lease terms, and vacancy status per unit
• Trailing 12-month income and expense statement (if available from seller)
• Pro forma income projection showing rent increases after renovations
• Per-unit rehab breakdown with before photos of each unit
• Cap rate analysis at current rents and at projected market rents
• Cash-on-cash return projections at different down payment scenarios (25% conventional, 3.5% FHA)
• House-hack scenario showing net monthly cost with owner living in one unit
• DSCR calculation showing debt service coverage ratio

When you use outreach tools to blast the deal, segment your list. Landlord buyers get the income-focused presentation. House-hack buyers get the live-for-free scenario. Flipper buyers get the ARV and total rehab scope. Matching the message to the buyer's strategy dramatically increases your response rate.

Common challenges with 3-4 unit deals

Tenant complications

Multi-family properties almost always have tenants. Your buyer needs to understand the existing lease obligations. In most states, a property sale does not terminate existing leases. If one tenant is on a 2-year lease at $200 below market, the buyer is stuck with that rate until the lease expires. Disclose all lease terms upfront to avoid surprises during due diligence.

Financing hurdles

While 3-4 units qualify for residential loans, the underwriting is stricter. FHA requires that the property be self-sufficient, meaning 75% of the gross rent must cover the mortgage payment. Conventional loans may require 6 months of cash reserves. VA loans limit the number of units an investor can finance. Make sure your buyer list includes investors who have already secured financing approval for multi-family.

Insurance costs

Insurance for multi-family is significantly higher than single-family, especially in flood zones or high-liability areas. Get an insurance estimate before marketing the deal so your income projections are accurate. A $3,000/year insurance bill versus a $6,000/year bill can change the cap rate by a full percentage point.

Deferred maintenance

Many 3-4 unit buildings are older construction with decades of deferred maintenance. Sewer lines, electrical panels, plumbing, and foundations can have issues that are not visible during a walkthrough. Recommend that buyers budget an additional 10-15% contingency on top of your repair estimate for hidden issues.

Building your multi-family buyer list

Use investor search tools to identify buyers who have recently purchased 2-4 unit properties in your market. These buyers are already familiar with multi-family underwriting and can close quickly. Also target:

• Local property management companies (they buy for clients)
• BiggerPockets multi-family forums and local Facebook groups
• Small apartment investors looking to add units efficiently
• Out-of-state investors looking for turnkey multi-family with property management in place

The bottom line

Triplexes and fourplexes are the most underserved segment in wholesale real estate. The buyer demand is high, the competition among wholesalers is low, and the assignment fees are larger than single-family. If you invest the time to learn multi-family valuation and build a targeted buyer list, these deals can become the most profitable part of your wholesaling business.
