First look

This is a 1899 Cathedral Hill mansion fourplex asking $655,975, and the numbers don't work. Our underwriting shows about -$2,472 a month and a 1.9% cap rate, and break-even is near $191,524. The listing gives no rents, no rent roll and no expenses, and the owner pays some utilities, so get the trailing-12 first. Photos show clean but dated interiors, an old basement and a lapsed-looking rental license. Unless the seller's rents are far above our roughly $1,100 per unit estimates, a showing only makes sense if the price drops a lot.

Things to consider

  1. Price is far above what the income supports Break-even is about $191K versus a $656K ask, so any purchase would need a major cut or much higher actual rents.
  2. Taxes and assessments take a big bite Non-homestead tax of $17,869 plus $2,647 in assessments eats a large share of likely rent.
  3. Utility bill-backs are a projection, not income RUBS is not in place yet and may be capped by St. Paul's 3% rule on sitting tenants, so don't count it.Listing says: “ownership implementing a RUBS utility reimbursement program across the portfolio beginning Q3 2026”
  4. Old building systems are unverified An 1899 build with radiators and a stone basement calls for inspection of the boiler, wiring and foundation before pricing in reserves.From photo 10
  5. Redevelopment upside is speculative A double lot may allow more units, but it needs zoning and heritage-district checks and doesn't fix the cash flow today.Listing says: “Situated on a double-wide lot”

From the photos

Listing photo 3
1 of 7Check

Exterior is painted in bold colors with a roof that appears reasonably intact; paint hides the condition of the wood siding, so check for rot

Listing photo 4
2 of 7Plus

Original woodwork and staircase look well kept, which has appeal but means old-building maintenance

Listing photo 5
3 of 7Check

Cast-iron radiators appear to heat the building, so it is likely a boiler system; ask about age and whether it's one or several

Listing photo 7
4 of 7Concern

Kitchen appears dated but serviceable, with basic white cabinets, laminate-type flooring and entry-level appliances; cosmetic updates only

Listing photo 9
5 of 7Check

Bathroom looks basic and tidy with a newer vanity and flooring; appears cosmetic

Listing photo 10
6 of 7Concern

Basement has coin-op washer and dryer, old stone walls, patched areas and exposed ducts; inspect for moisture and foundation condition

7 of 7Check

No photos of the boiler, electrical panels, roof close-up or upper units, so key systems are unseen

Based on 10 of the listing photos. Photos can hide as much as they show; an inspection is the real answer.

Red flags and opportunities

Watch for

  • highNo rents, rent roll or expenses given; income can't be verified Listing says: Utilities are currently partially owner-paid · AI review
  • highTax bill is $17,869 on a non-homestead basis, which is heavy against likely rents Based on: data: county.tax · AI review
  • medium$2,647 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 012823210215: special assessments (payable 2026) = $2,646.84
  • mediumAsking is $464,451 above the price where cash flow breaks even ($191,524) at the default scenario. Based on: Derived: price $655,975 vs. break-even $191,524
  • 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"
  • mediumRental license shows 'Renewal Due' with an expiry in June 2025; confirm it is current for 4 units Based on: data: city.rental_license · AI review
  • mediumBasement shows bare stone walls, exposed ductwork and old plumbing; foundation and moisture need inspection Based on: photo 10 · AI review

Opportunities

  • Long time on market: room to negotiate. Based on: Listing data: 143 days on market
  • Double-wide lot could support redevelopment or added units, subject to zoning Listing says: the property offers both immediate tenant appeal and long-term redevelopment potential · AI review
  • Coin laundry gives a small income stream; ask what it actually collects Listing says: Additional amenities include coin-operated laundry · AI review
  • 143 days on market suggests room to negotiate hard Based on: data: listing.days_on_market · AI review

Questions for the agent

  • Can I see the current rent roll, lease dates and security deposits for all four units?
  • What are the trailing-12 expenses, including which utilities the owner pays and their cost?
  • What are the $2,647 special assessments for, and will the seller pay them at closing?
  • Is the 4-unit rental license current, and when was the last city inspection?
  • How old are the boiler, roof, wiring and plumbing, and what was done in the renovation?
  • Why is the owner selling now, and are other portfolio properties listed too?

Bottom line

Beautiful old building, but at $656K it loses about $2,500 a month on our numbers, so only a big price cut or much higher real rents could make it work. AI-assisted summary
