First look

This is a big 1901 duplex in Park Rapids, asking $239,900, with 6 beds and 2,888 sq ft. Our underwriting at asking price loses about $202 a month with a 5.4% cap rate, and break-even price is about $202K, so it needs a roughly $38K cut to work. The description gives no rents, no lease status and no utilities, and it's been on the market 70 days. The interiors look dated but livable, with paneling, older cabinets and newer vinyl plank flooring. Get the rent roll, the heat source and who pays it, and the actual tax bill before a showing. It is worth a look only if the price comes down or the real rents beat our $1,175 estimate per unit.

Things to consider

  1. Price is above what the numbers support Our underwriting shows negative cash flow of about $202 a month at asking. You would need a price near $202K to break even.
  2. Rents are unknown The description gives no rents or lease terms. Our estimate is about $1,175 per unit, so verify against actual leases before relying on it.
  3. Dated interiors mean capex Kitchens, baths and paneling look original, so budget for updates before pushing rents. Tenant turnover could add cost.From photo 5
  4. Unverified taxes and unit count No parcel match means the tax bill is a guess, and an investor may pay more than the current owner.
  5. Old building with unknown systems A 1901 build can hide old wiring, plumbing and a foundation that needs work. Get an inspection.
  6. Riverside location may bring flood or dam-related questions Check flood zone status and insurance cost, since the property sits near the river and hydro dam.Listing says: “overlooking the river and the hydro dam”
