The up-down duplex, two stacked flats in a house that looks like a single-family from the street, is the signature small rental of St. Paul. You will find them by the thousands in Mac-Groveland, Merriam Park, Hamline-Midway and Como, many built in the 1910s and 1920s.
In short: LendingStreet finances St. Paul duplexes, triplexes and fourplexes with DSCR loans that qualify on the combined rent of all units, with no W-2s or tax returns. Loans start at $150,000, purchases go up to 80% LTV and cash-out up to 75%, LLC borrowers are standard and 30-year terms are available. In St. Paul, rent stabilization, the Fire Certificate of Occupancy and non-homestead taxes are the local factors that most affect the numbers.
Up-down duplexes dominate the city's 2-4 unit stock, typically with a separate entrance for each flat, separate or shared basements and, in older buildings, a single boiler. Side-by-side doubles and larger Victorian homes converted to three or four units are common in Summit-University, Cathedral Hill, Dayton's Bluff and the West Side. Purpose-built fourplexes from the mid-century show up along busier streets and in the Midway, often with off-street parking and simpler layouts that are easier to maintain.
Prices vary widely. Duplexes near the colleges in Mac-Groveland and Merriam Park sell for considerably more than similar buildings in Frogtown, Payne-Phalen or the North End, and rents differ accordingly.
Duplexes have long been a common first investment in St. Paul, which means good ones attract competition. Investors who move fastest usually have their financing lined up before they make an offer, with a clear view of how the property's current rent and taxes translate into a loan amount.
A quick guide to where 2-4 unit investors buy in St. Paul.
| Area | Common building | Tenant base | Key consideration |
|---|---|---|---|
| Mac-Groveland / Merriam Park | Up-down duplexes | Professionals, students | Student housing overlay |
| Hamline-Midway / Como | Up-down duplexes | Workers, students | Rising prices near Allianz Field |
| Summit-University / Cathedral Hill | Converted Victorians | Mixed, near Selby Ave | Historic review, older systems |
| Payne-Phalen / Dayton's Bluff | Duplexes, triplexes | Families, long-term renters | Condition, turnover |
| West Side | Victorians, duplexes | Families, downtown workers | River bluff lots, older homes |
St. Paul has updated its residential zoning in recent years to allow more 2-4 unit housing on lots that were once limited to single-family homes, as part of a broader push for more housing choices. That creates opportunities to add units or build infill duplexes and fourplexes, subject to lot size, design and building code requirements.
Near the University of St. Thomas, a student housing overlay district has limited how closely student-occupied rentals can be spaced. If you plan to rent to students in Mac-Groveland or Merriam Park, check how the overlay applies. For any building, confirm the legal unit count with the city before you buy; underwriting uses the legal count.
This example is illustrative and not a quote. An investor buys an up-down duplex in Hamline-Midway for $455,000. Each flat leases for $1,750, for combined rent of $3,500 a month.
At 75% LTV the loan is $341,250. Estimated principal and interest on a 30-year term is about $2,328. Non-homestead property taxes are about $560 a month and insurance about $220, for a total payment of about $3,108. DSCR is about 1.13x. Because rent increases on existing tenants are limited by the city ordinance, the example uses current rent only, and the investor keeps leverage at 75% rather than 80% to leave room.
| Item | Amount |
|---|---|
| Purchase price | $455,000 |
| Loan at 75% LTV | $341,250 |
| Combined rent, 2 units | $3,500 |
| Estimated principal and interest | $2,328 |
| Non-homestead property taxes | $560 |
| Insurance | $220 |
| Total payment | $3,108 |
| DSCR | About 1.13x |
St. Paul's voter-approved rent stabilization ordinance originally capped most annual increases at 3%, and the city has since amended it with exemptions, rules for resetting rent between tenants and an exception process. Because the ordinance has changed more than once, check the current version and how it applies to the specific building you are buying.
For DSCR purposes, assume today's rent is close to next year's rent. Buy at a price where current leases, or supportable market rent on vacant units, clear the ratio.
Duplexes in Minneapolis and in suburbs such as West St. Paul, South St. Paul and Roseville are outside St. Paul's ordinance, which is one reason some investors compare buildings across the city line before buying.
St. Paul's Fire Certificate of Occupancy program inspects rental housing on a cycle. Before closing, ask for the building's certificate status and recent inspection reports. Open orders on egress windows, smoke detectors, electrical panels or boilers are common in older duplexes and should be priced into your offer.
Minnesota winters add their own items: ice dams, frozen pipes in vacant units, and old boilers serving both flats. Separate heating systems cost more upfront but make the building easier to manage.
An investor-owned duplex is classified as non-homestead rental property in Minnesota and taxed at a higher share of value than an owner-occupied home. If the seller lived in one unit, the bill you inherit will rise. St. Paul's special assessments for street and utility work also appear on the tax statement, so review the full statement from Ramsey County.
Five to eight unit buildings follow the same DSCR basics with leverage that varies by program; see our St. Paul 5-8 unit page.
