First look

This is a 1874 side-by-side duplex asking $345,000 with no rents, no lease terms and no repair history in the listing. Our underwriting shows about -$535 a month at ask and a 4.5% cap rate, and break-even is near $245,000. That gap is too big to close with a small negotiation. Unless the seller shows rents far above our $1,375 per unit estimate, it doesn't work at today's rates. If you still want a look, get the rent roll, 12 months of utility bills, the special assessment details and the rental license status before a showing. Then walk it for foundation, wiring and heat.

Things to consider

  1. Price is far above what rents support At $345K the deal loses roughly $535 a month in our model. It needs a much lower price or much higher rents.
  2. Income is unverified With no rents or leases stated, you're relying on our estimate of about $1,375 per unit. Get the rent roll.
  3. Utility costs are unclear and RUBS is only a plan Owner-paid utilities eat cash flow, and billing tenants back may be restricted by the 3% cap.Listing says: “ownership implementing a RUBS utility reimbursement program across the portfolio beginning Q3 2026”
  4. Old building with dated finishes An 1874 build and a dated kitchen mean you should budget for capex before raising rents.From photo 8
  5. Special assessments and pending license The $1,263 assessment adds to carrying costs, and a pending license could mean required repairs.

From the photos

Listing photo 1
1 of 7Check

Exterior shows two front entries and wood lap siding that appears to need paint. The asphalt shingle roof looks fairly newer, but confirm its age.

Listing photo 8
2 of 7Concern

Kitchen has an older white gas range and fridge, laminate counters, a tin-look backsplash and vinyl plank flooring. It looks dated and budget-updated.

Listing photo 5

Hardwood floors and original woodwork look intact in the living areas, which is a positive for character and durability.

Listing photo 4

A floor register shows forced-air heat in the hallway. Confirm whether each unit has its own furnace.

Yard is shared and appears to have a play set and garden beds. No garage or off-street parking is visible; street parking only appears likely.

Listing photo 9

Upstairs bedroom has sloped ceilings and original trim, with textured ceilings. No obvious water stains are visible in these shots.

No photos of basement, mechanicals, electrical panels, bathrooms or the second unit, so key systems are unseen.

Red flags and opportunities

Watch for

  • highUnusual ownership (land trust, ground lease or co-op): resale price limits or lease terms can cap your upside. Listing says: "to downtown St Paul, public transportation, Mississippi Market Co-Op , and the restaurants, shopping, and entertainment along"
  • highListing gives no rents, lease terms or expenses, so income can't be verified. Based on: data: rent_estimate · AI review
  • medium$1,263 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 322922410002: special assessments (payable 2026) = $1,262.58
  • mediumProjected utility bill-backs (RUBS) are not income yet, and in St. Paul they may count toward the 3% cap. Listing says: "are currently partially owner-paid, with ownership implementing a RUBS utility reimbursement program across the portfolio beginning Q3"
  • mediumOwner pays some utilities but the listing doesn't say which ones or how much. Listing says: Utilities are currently partially owner-paid · AI review
  • mediumRental license is only Pending, so check for open inspection items. Based on: data: city.rental_license · AI review
  • mediumBuilt 1874, so expect old wiring, plumbing and foundation. Nothing in the listing covers updates. Based on: data: listing.year_built · AI review
  • lowInterstate is about 218 m away, so expect road noise that may weigh on rents and resale. Based on: data: highway · AI review

Opportunities

  • Long time on market: room to negotiate. Based on: Listing data: 143 days on market
  • Utility cost recovery could lift NOI, but only if lease terms and the St. Paul 3% cap allow it. Listing says: Future ownership will have the opportunity to improve NOI through utility cost recovery · AI review
  • 140 days on market gives room to push price hard. Based on: data: listing.days_on_market · AI review
  • Side-by-side layout is more private for tenants and may help retention. Listing says: The side-by-side layout provides added privacy and functionality · AI review

Questions for the agent

  • What are the current rents, lease end dates and deposits for each unit?
  • Which utilities does the owner pay, and what were the last 12 months of bills?
  • What are the $1,263 special assessments for, and are they paid off at closing?
  • Why is the rental license pending, and are there open inspection orders?
  • What are the ages of the roof, heating, water heater and electrical panels?
  • Why was the property listed with other properties from the same owner, and is the owner motivated?

Bottom line

At $345K this loses about $535 a month on our numbers; it only works near $245K or with rents far above what we estimate. AI-assisted summary
