Buying Your First Small Multifamily in Las Vegas, Duplex to Fourplex Math

Most first time investors in Las Vegas start with a single family rental because it feels familiar. But there is a strong argument for skipping straight to a duplex, triplex, or fourplex. Properties with two to four units still qualify for conventional residential financing, which means you get commercial style income with residential style loan terms. One roof, one tax bill, one insurance policy, and two to four rent checks. We already published a detailed guide on managing duplexes and fourplexes in Las Vegas, so this article covers the other half of the equation, actually finding, financing, and penciling one of these buildings before you own it.

Why the 2 to 4 unit category is its own animal

Federal lending rules draw a bright line at four units. A building with one to four units is residential for underwriting purposes, so it is eligible for 30 year fixed conventional loans backed by Fannie Mae and Freddie Mac. A fifth unit pushes you into commercial lending, which usually means shorter terms, balloon payments, higher rates, and a loan sized off the property income rather than your personal finances. That bright line is why fourplexes trade at a premium per unit compared to small apartment buildings. You are paying for access to cheap, long term, fixed rate debt.

The category also behaves differently on the ground. Vacancy hurts less because one empty unit in a fourplex is 25 percent of your income, not 100 percent. Expenses per unit run lower because you are maintaining one structure. And in the Las Vegas valley, the 2 to 4 unit stock is concentrated in specific, older neighborhoods, which shapes both the purchase price and the tenant profile you should expect.

Where small multifamily actually sits in the valley

Las Vegas is not like older cities where duplexes are scattered through every neighborhood. Most of the valley was built after 1990 as master planned single family communities, and HOA controlled areas like Summerlin and most of Henderson have almost no 2 to 4 unit product at all. The small multifamily stock clusters where the city grew in the 1950s through the 1970s.

• Downtown adjacent neighborhoods. Huntridge, John S. Park, and the blocks east of Las Vegas Boulevard between Charleston and Sahara hold a lot of 1950s and 1960s duplexes and fourplexes. Some pockets are gentrifying, with renovated units pulling rents that would have seemed impossible ten years ago. Block by block due diligence matters here more than anywhere else in the valley.
• The Maryland Parkway corridor. The stretch between Sahara and Tropicana, near UNLV and Sunrise Hospital, is dense with fourplexes and small courtyard buildings. Student and medical worker demand keeps units filled, and the planned transit improvements along Maryland Parkway are a long term tailwind.
• East Las Vegas and Sunrise Manor. The area east of Eastern Avenue out toward Boulder Highway and Nellis has the largest inventory of workforce priced 2 to 4 unit buildings. Price per unit is the lowest in the valley, and so is average rent, so the math can still work if you underwrite repairs honestly.
• Older North Las Vegas. The original townsite south of Craig Road has duplex and fourplex stock at entry level prices. Check jurisdiction carefully, because North Las Vegas is a separate city with its own business licensing and code enforcement.

One practical note on jurisdiction. A rental in unincorporated Clark County, the City of Las Vegas, the City of North Las Vegas, and the City of Henderson each requires its own local business license, and a fourplex may be licensed differently than a single family rental. Confirm the licensing requirement for the specific parcel before you close, not after.

How conventional multi unit loans really work

Conforming loan limits scale up with unit count, and this surprises most first time buyers. Limits are adjusted every year, and for 2025 the baseline figures were roughly $806,500 for one unit, $1,032,650 for two units, $1,248,150 for three units, and $1,551,250 for four units. Clark County follows the baseline, not the high cost limits used in coastal markets. In other words, nearly every fourplex in the Las Vegas valley fits inside a conforming loan. You can verify the current year figures on the Fannie Mae conforming loan limits page, which publishes the values by unit count and county.

Down payment requirements depend on how you will use the building.

• Pure investment purchase. Expect 25 percent down on a 2 to 4 unit investment property under standard conventional guidelines, and plan for the lender to require several months of reserves, often six months of the full housing payment, on top of your down payment and closing costs.
• Owner occupied purchase, the house hack. If you will live in one unit for at least a year, conventional financing on a 2 to 4 unit primary residence is available with as little as 5 percent down under guideline changes Fannie Mae made in late 2023. This is the single biggest financing advantage in the entire category. A buyer with $50,000 can control a fourplex that a pure investor would need more than $200,000 to buy.

The rent credit, how lenders count income you do not have yet

Here is the part of underwriting that makes multifamily qualification easier than people expect. When you buy a 2 to 4 unit property, the appraiser completes a small residential income property report, commonly called Form 1025, which includes a market rent analysis for each unit. The lender can then credit a portion of those projected rents, typically 75 percent after a vacancy and expense haircut, toward your qualifying income. So if the appraiser supports $5,900 per month in total market rent, roughly $4,425 gets added to your income side of the debt to income calculation. On an owner occupied purchase, the rent from the units you are not living in gets the same treatment. This is how W2 earners with ordinary salaries qualify for seven figure fourplex loans.

If your personal income or tax returns will not support conventional underwriting, DSCR loans that qualify off the property income alone are widely available in Nevada, at a rate premium. We walk through those tradeoffs in our guide to financing Las Vegas investment property.

A worked fourplex pro forma with honest numbers

Let us pencil a realistic east valley fourplex so you can see the full picture, including the uncomfortable part. Assume a 1970s fourplex near the Maryland Parkway corridor, four two bedroom units, priced at $800,000.

Income

• Four units at $1,475 per month is $5,900 per month, or $70,800 per year in gross scheduled rent.
• Subtract 5 percent for vacancy and collection loss, $3,540, leaving effective gross income of $67,260.

Operating expenses

• Property taxes, about $4,800. Clark County effective rates are low by national standards, but remember the 3 percent annual cap on tax bill increases applies to primary residences, while rentals fall under the higher 8 percent cap, so model future increases accordingly.
• Insurance, about $3,600. Multi unit policies price higher per door than single family.
• Water, sewer, and trash, about $3,000. Most older fourplexes are master metered for water, so the owner pays it. This is a line item single family investors forget entirely.
• Professional management at 8 percent of collected rent, about $5,380.
• Repairs and turnover, about $4,200. Four separate kitchens, four water heaters, and 1970s galvanized plumbing earn every dollar of this budget.
• Capital reserve, about $2,400 set aside for the roof, parking surface, and HVAC replacements that are coming whether you budget for them or not.

Total expenses come to roughly $23,380, which leaves net operating income of about $43,880. That is a 5.5 percent cap rate on the $800,000 price, which is right in the realistic band for stabilized east valley small multifamily.

Now the debt, and the honest conclusion

As a pure investment at 25 percent down, you would borrow $600,000. At 6.5 percent on a 30 year fixed, principal and interest run about $3,792 per month, or $45,504 per year. Set that against $43,880 of NOI and the property loses about $1,600 per year. The debt service coverage ratio is 0.96, and most DSCR lenders want at least 1.0 to 1.2. That is not a spreadsheet error. It is the current market, and any listing pro forma showing this same building throwing off $800 a month in cash flow is using fantasy expense numbers.

The deal still works through three levers. First, a larger down payment. At 35 percent down the loan drops to $520,000, payments fall to about $39,444 per year, and the building cash flows modestly while paying down principal and capturing rent growth. Second, rent upside. If in place rents are $200 under market because a tired owner never raised them, stabilized income jumps more than $9,000 per year and the same building pencils at the same price. Third, the house hack. Live in one unit with 5 percent down, let three tenants cover most of the mortgage, and convert the property to a full rental after the occupancy period. Whichever lever you use, run the complete numbers the same disciplined way we describe in our guide to analyzing a rental property before you buy in Las Vegas.

Due diligence items specific to 2 to 4 unit buildings

• Estoppel information on inherited tenants. You will likely close with tenants in place, and you inherit their leases as written. Nevada law caps security deposits at three months of rent under NRS 118A.242, and those deposits must transfer to you at closing. Get every lease, every deposit ledger, and written confirmation of who is behind on rent before you release contingencies.
• Meter configuration. Separately metered electric is standard in Las Vegas fourplexes, but confirm gas and water. Master metered utilities move real money from your pocket to the expense column every month.
• Sewer scope and roof. A 1970s building has 50 year old drain lines under the slab. A sewer camera inspection costs a few hundred dollars and can save you a five figure repipe surprise.
• Code and licensing history. Pull the permit history and check for open code enforcement cases with the relevant jurisdiction. Unpermitted unit conversions, such as a garage turned into a fifth unit, can kill your conventional financing and your insurance.

Plan the management before you close

A fourplex is four sets of tenants, four move in inspections, and four times the chances of a 2 a.m. maintenance call, all governed by NRS 118A habitability and notice requirements that do not care whether you own one unit or four. Interviewing a manager during escrow, not after your first vacancy, also gives you a second professional opinion on your rent assumptions while you can still renegotiate or walk. The IRES team reviews rent comps and turnover budgets for buyers in escrow regularly, and our Las Vegas property management services cover 2 to 4 unit buildings across the valley, from Huntridge duplexes to Boulder Highway fourplexes.

Small multifamily is the best training ground in real estate. The loans are residential, the income is diversified, and the mistakes are survivable. Get the acquisition math honest, and the building will teach you the rest.
