First look

This is a thin listing: two 2-bed/1-bath units, a detached 2-car garage, and nothing on rents, leases, heat or systems. At $170K our model shows about $514/mo cash flow and a 10.0% cap rate using $1,450 per unit, but those rents are our estimates, not the seller's numbers. The price is under the 2022 sale of $207K and well under the county's $249K value, so ask why it's cheap. The photo shows an 1890 house with dated siding and a small front step, so condition is the big unknown. Get the rent roll, utility setup and the assessment details first, then decide if it's worth a showing.

Things to consider

  1. Cash flow depends on estimated rents Our $514/mo uses $1,450 per unit, which the seller hasn't confirmed. If actual rents are lower, cash flow shrinks fast.
  2. Rent increases are capped in St. Paul Sitting tenants can only see 3% annual increases, so below-market rents can't be fixed quickly.
  3. 1890 building with unknown systems Heat, wiring, plumbing and foundation age drive repair costs on a house this old, and none are disclosed.
  4. Non-owner-occupied tax and assessments The county bill shows non-homestead tax plus $1,701 in assessments, which cut into income if they recur.
  5. Pending rental license A pending license can mean an open inspection with required repairs before you can legally collect rent.

Only one front entry is visible, and the unit split is unclear. Confirm how the upper and lower units are accessed and metered.

Red flags and opportunities

Watch for

  • highNo rents, lease terms or occupancy given. Our cash flow rests on estimated rents, not actual ones. Based on: data: rent_estimate · AI review
  • medium$1,701 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 292922420063: special assessments (payable 2026) = $1,701.42
  • mediumRental license shows Pending status, so the units may not be fully licensed yet. Confirm both units can legally be rented. Based on: data: city.rental_license · AI review
  • mediumBuilt in 1890 with no information on roof, wiring, plumbing or foundation. Expect old-house surprises. Based on: data: listing.year_built · AI review
  • lowSells for less than the 2022 purchase price and the county market value. That may mean condition problems or a motivated seller. Based on: data: county.last_sale_price · AI review

Opportunities

  • Long time on market: room to negotiate. Based on: Listing data: 36 days on market, 2 price cuts
  • Owner-occupy one unit while renting the other. The listing itself pitches this angle. Listing says: explore the possibilities of owner-occupancy · AI review
  • Price sits well below the county market value and our break-even price of $266K, leaving room if rents and condition check out. Based on: data: underwriting.break_even_price · AI review
  • Detached 2-car garage gives off-street parking, which helps rentability. Listing says: A detached 2-car garage provides additional parking and storage. · AI review

Questions for the agent

  • What are the current rents, lease end dates and security deposits for each unit? Are any month-to-month?
  • What are the $1,701 in special assessments for, and will the seller pay them at closing?
  • Which utilities does the owner pay, and are heat and electric separately metered for each unit?
  • What are the ages of the roof, furnace, water heater and electrical panel?
  • Why is the rental license pending, and has the city inspected the property?
  • Why was it listed under the 2022 sale price, and has there been any price change in 33 days?

Bottom line

Numbers look decent on estimated rents, but with no rent roll, no system details and a pending license, this is a showing-plus-verification candidate, not a sure thing. AI-assisted summary
