First look

This is a 4-unit in downtown Mankato listed at $375K, with $3,075/month stated, or about $36,900 a year gross. Our underwriting at asking shows roughly -$700/month and a 4.15% cap rate, and break-even is near $243,500. That is a big gap, so the price needs to come down a lot or the numbers have to prove better than we assume. The stated rents are per-unit figures we don't have from the description, so ask for the rent roll, leases and 12 months of expenses first. Check the heat setup: photos show both radiators and electric baseboard, which could mean mixed systems and possibly owner-paid heat. At 171 days on market there's room to negotiate, but I'd only tour it at a price near break-even.

Things to consider

  1. Price is far above break-even Our numbers show about -$700/month at asking and a 4.15% cap rate. Even a large cut leaves little room for error.
  2. Rent is below market, but the upside is slow to realize Our estimates are above the stated rents. Two units open in August, so you could test market rents there, but the other two depend on lease timing.
  3. Unverified taxes and unit count We couldn't match a county record, so taxes and legal unit count are unconfirmed. Taxes are a big expense in the cash flow model.
  4. Old building with dated systems An 1885 build with mixed heat types suggests aging mechanicals. Only the roof is confirmed as updated.Listing says: “Newer roof (2019).”
  5. Tenants pay electric, but heat is unclear If heat is owner-paid, expenses rise and the deal weakens further.Listing says: “Tenants pay electric and Wi-Fi, helping offset owner expenses.”
  6. Long listing time 171 days on market suggests the price is too high and leaves leverage for a low offer.

From the photos

Listing photo 1
1 of 8Plus

Painted brick exterior looks reasonably maintained, with a detached one-car garage and a paved shared driveway for parking.

Listing photo 4
2 of 8Check

Shared laundry room shows coin-style washer and dryer, a radiator and an electric wall heater, so heat appears mixed. The finishes look dated.

Listing photo 5
3 of 8Check

Sunroom has newer vinyl-plank flooring and electric baseboard heat, but drop-ceiling tiles and plain finishes look cosmetic.

Listing photo 6
4 of 8Concern

Kitchen has original-looking brown cabinets, an electric range, a white fridge and dishwasher, and a drop ceiling. It appears dated but serviceable.

Listing photo 7
5 of 8Check

Bathroom uses faux-stone wall panels and a molded double vanity. It appears clean and low-maintenance, but dated.

Listing photo 9
6 of 8Plus

Living room has tall ceilings, original-looking woodwork, built-ins and a radiator. It is a strong character unit, though photos look staged and may not reflect the other units.

Listing photo 10
7 of 8Check

Compact kitchen with new backsplash and cabinet hardware, but a very small sink and stove. It appears to be a cosmetic refresh of a small unit.

8 of 8Check

No photos of the boiler, electrical panels, basement or the upper units, so the main systems are unverified.

Red flags and opportunities

Watch for

  • highHeat type and who pays for it is not stated. Photos show radiators and electric baseboard, so systems may be mixed. Owner-paid heat would cut cash flow further. Listing says: Tenants pay electric and Wi-Fi, helping offset owner expenses. · AI review
  • mediumCouldn't match this address to a county parcel record, so taxes and unit count are unverified. Public record: County parcels: no match for 303 BROAD ST N
  • mediumAsking is $131,463 above the price where cash flow breaks even ($243,537) at the default scenario. Based on: Derived: price $375,000 vs. break-even $243,537
  • mediumBuilt in 1885, so check wiring, plumbing and foundation. Only the roof age is given. Based on: data: listing.year_built · AI review
  • mediumTwo bottom units are coming open in August, so income is not secured and turnover/vacancy costs are near-term. Listing says: Bottom two units will be available in August. · AI review
  • mediumLease status and terms are not given for any unit. The $3,075 total may be from a mix of leases, month-to-month, or projections. Listing says: generating $3,075/month in rental income · AI review
  • lowPhoto 10 shows an old, very small kitchen with a basic sink and a two-door fridge/stove combo, which looks like a dated studio-style unit. Check that it is a legal, licensed unit. Based on: photo 10 · AI review

Opportunities

  • Long time on market: room to negotiate. Based on: Listing data: 171 days on market
  • Current rents are below market. Rents can reset to market at renewal. Based on: Listing rents vs. our market estimate: Unit 2: 1 bed / 1 bath $650 vs $800, Unit 3: 1 bed / 1 bath $675 vs $800, Unit 4: 1 bed / 1 bath $700 vs $800
  • Rents are below market per our estimate. Resetting at renewal or turnover could add income, though the two vacating units are the easiest test. Based on: data: rent_estimate · AI review
  • Owner-occupant option: live in one unit and offset the mortgage, which may open up different financing. Verify with a lender. Listing says: Owner occupants are welcome. · AI review
  • 171 days on market suggests the seller may be flexible on price. Based on: data: listing.days_on_market · AI review

Questions for the agent

  • Can I see the rent roll, current leases and 12 months of expenses?
  • What is the heat source for each unit, and who pays for it?
  • Are all four units licensed as rentals with the city of Mankato, and is the lower-level unit legal?
  • What are the annual taxes and any special assessments?
  • What are the ages of the boiler, water heater and electrical panels, and is the wiring original?
  • Which units are vacating in August, and are those rents part of the $3,075?

Bottom line

At $375K this loses about $700 a month by our math; it only works near $243K, so it is worth a look only after a deep price cut. AI-assisted summary
