First look

This is a 1880 up/down duplex in South St. Paul at $340K, with a 3-bed upper and a 4-bed lower. Our underwriting shows about $699/month cash flow and an 8.9% cap at asking, but that rests on rent estimates of $2,100 and $2,250, because the listing gives no actual rents or lease terms. Taxes and unit count are unverified since we couldn't match the parcel, so confirm both first. The photos show mixed condition: the lower unit looks dated, and the 'recently renovated' upper claim needs a look in person. It's worth a showing if the rent roll backs up the estimates and the heat and electrical check out.

Things to consider

  1. Rents are our estimates, not actuals The $699/month cash flow depends on $2,100 and $2,250 rents. If actual rents are lower, the deal weakens fast at today's rates.
  2. Highway proximity I-494 is within 74 m, and noise can cap rents and lengthen vacancy, especially on the upper unit.
  3. Taxes and unit count unverified No parcel match means the tax bill is a guess. An investor may pay more than the seller's tax, which cuts cash flow.
  4. Condition is uneven across units The upper is claimed as renovated, but the lower looks dated. Budget for kitchens, baths and the dryer vent, and expect repairs on an 1880 building.From photo 6
  5. Large bedroom counts mean heavy wear Seven bedrooms across two units usually means bigger families and more wear on floors and baths, so keep repairs reserves higher.Listing says: “The lower unit features four large bedrooms, two full bathrooms within unit”

From the photos

Listing photo 1
1 of 8Check

Exterior is green siding with an exterior metal stair on the side, which appears to be a second entrance for the upper unit; siding looks serviceable

Listing photo 2

Chain-link fenced yard with a shared walk and two mailboxes, consistent with two units

Listing photo 3
3 of 8Check

Upper-unit living areas look clean with newer carpet and paint, which appear cosmetic rather than a full renovation

Listing photo 5
4 of 8Concern

Lower-unit kitchen has a drop ceiling, laminate floor and what appears to be baseboard heat; fairly basic finish

Listing photo 6
5 of 8Concern

Second kitchen has a dated vinyl floor, painted brick backsplash, and old ceiling and range hood; looks original or early update

Listing photo 8
6 of 8Concern

One bath has a newer vanity and toilet; the other has an old pedestal-style sink, parquet-type floor and wear, so bath condition is uneven

Listing photo 10
7 of 8Concern

Dryer vent is flexible foil duct run across the wall; replace it for fire safety. Washer and dryer present in the unit

Red flags and opportunities

Watch for

  • mediumCouldn't match this address to a county parcel record, so taxes and unit count are unverified. Public record: County parcels: no match for 243 PARK ST W
  • mediumAbout 74 m from I 494: traffic noise usually costs $50–100/month in rent. Based on: OpenStreetMap: nearest motorway (I 494) at 74 m
  • mediumNo rents, lease terms or utility info given; cash flow depends on our estimates Based on: data: rent_estimate · AI review
  • mediumHeating type, age and who pays are not stated; photo shows baseboard-style heat in the lower kitchen Based on: photo 5 · AI review
  • medium1880 build with a lower unit that has four bedrooms and two baths; check legality, egress and permits for the layout Listing says: The lower unit features four large bedrooms, two full bathrooms within unit · AI review

Opportunities

  • Lower unit looks dated (drop ceiling, old flooring, outdated bath); a refresh could support rents toward the high estimate Based on: photo 8 · AI review
  • Detached 2-car garage off the alley is a real plus for tenants and could be rented separately Listing says: A spacious detached 2 car garage can be accessed from the alley. · AI review
  • In-unit laundry in both units helps keep rents and retention strong Listing says: In-unit laundry machines in each unit. · AI review

Questions for the agent

  • What are the current rents, lease end dates and security deposits for each unit? Are both occupied?
  • What heats each unit, and who pays heat, water and electric?
  • What was renovated in the upper unit, when, and was it permitted?
  • Is the lower-unit layout (4 beds, 2 baths) legal, and does the city rental license cover both units?
  • What are the real property taxes and any special assessments?
  • Why has it been on the market 52 days, and how old are the roof, panel and water heaters?

Bottom line

Numbers look decent on paper at $340K, but with no rents, unverified taxes and mixed condition, treat it as a showing candidate until the rent roll and systems check out. AI-assisted summary
