First look

This is a 1969 up/down split-level duplex asking $315K, and the numbers don't work. Our underwriting shows about -$711/month at 20% down, a 3.7% cap rate, and a break-even price near $181K. The description gives no rents, only that Unit 1 is county-assisted and Unit 2 is remodeled, so get the rent roll and leases first. Also check the rental license, since the city has none on file. The garage rental and the shared driveway are worth a look, but at this price I'd only tour it if the seller is far more flexible.

Things to consider

  1. Price is far above what the rents support At $315K the model shows negative cash flow and a 3.7% cap rate. Break-even is about $133K lower.
  2. Rents are unstated and one unit is subsidized Without a rent roll you can't verify income. Subsidized rent is dependable but follows program limits and inspections.Listing says: “Unit 1 is county-assisted with payment delivered direct.”
  3. Rental license and assessments need checking No rental certificate is on file and there are $572 in assessments. Either could add cost or delay.
  4. Remodel claims apply only to Unit 2 Unit 1 may be dated, and photos show older bathroom finishes. Budget for updates before expecting higher rents.From photo 2
  5. Garage and parking give some upside Extra parking, a five-car rear lot and garage bays could add modest income, but the amounts are small next to the cash flow gap.Listing says: “room for five cars and an oversized two-car garage”

From the photos

Listing photo 1
1 of 7Plus

Split-level brick-look exterior appears in decent shape. The roofline looks straight and no obvious damage is visible.

2 of 7Check

Both a main-level and lower-level entry area are visible, but the listing says the units enter from the rear. Confirm how the units are laid out and entered.

3 of 7Check

Wall-mounted utility meters and conduit are visible on the side of the house. Confirm how many meters there are and which unit each serves.

Wall-mounted window A/C units appear in several windows, so there may be no central air. Check cooling and tenant comfort.

Listing photo 3
5 of 7Check

Baseboard hot-water or electric heaters appear in the bathroom and the dining area, and the facts say heat is central. Confirm what the heating system actually is.

Bathroom has older pink tile flooring and an older vanity. Likely original or dated finishes in the unit pictured.

Red flags and opportunities

Watch for

  • mediumNo rental certificate (CofO) on file in the city's data. Ask whether the building is licensed as a rental and when it was last inspected. Public record: St. Paul Certificate of Occupancy – Residential: no record for 380 LARPENTEUR AVE E (dataset last updated mid-2025)
  • mediumAsking is $133,629 above the price where cash flow breaks even ($181,371) at the default scenario. Based on: Derived: price $315,000 vs. break-even $181,371
  • mediumUnit 1 income is county-assisted, so the rent is tied to program rules and inspections. Ask about the amount and contract terms. Listing says: Unit 1 is county-assisted with payment delivered direct. · AI review
  • low$572 in special assessments on the payable 2026 tax bill (often street, sewer or code-enforcement charges). Ask what they're for, whether they continue, and whether the seller pays them off at closing. Public record: Ramsey County parcel 202922220011: special assessments (payable 2026) = $572.02
  • lowHalf the garage is rented to Unit 2, so it is not extra income and may be part of that unit's rent. Clarify. Listing says: Half the garage currently rents to Unit 2. · AI review
  • lowHighway about 360 m away; noise may affect rentability and tenant turnover. Based on: data: highway · AI review

Opportunities

  • Rent the garage bays or the lockable shop for storage income. Listing says: rent the garage bays for storage · AI review
  • Parking and laundry fees could add income, but they may be limited on existing St. Paul leases. Listing says: charge for off-street parking, charge a laundry access fee · AI review

Questions for the agent

  • What are the actual rents, lease dates and security deposits for each unit?
  • What are the county assistance amount, contract terms and last inspection result for Unit 1?
  • Is the property licensed as a rental, and when was it last inspected?
  • What are the $572 special assessments for, and does the seller pay them off at closing?
  • How is the garage rented, to whom, and for how much? Is it on a separate meter as stated?
  • Who pays heat, water and trash, and what do the utilities cost per year?

Bottom line

A tidy-sounding duplex, but at $315K it loses about $700 a month in our model and only works near $180K. AI-assisted summary
