First look

This is a low-priced Fairmont triplex at $174,900 with three roughly equal units, and our model shows about $191/month cash flow and a 7.7% cap at ask. That depends on unverified taxes, since we couldn't match a county parcel. The description is thin: no rents, no lease terms, no utility details beyond 'sub metered'. Photos show a low-slung one-story building with cosmetic updates, an unfinished basement, and one furnace and washer/dryer visible, so confirm what each unit really has. Worth a showing if the rent roll and tax bill hold up, and if the seller-agent's story on the sub-metering checks out.

Things to consider

  1. Rents are not stated anywhere Cash flow rests on our estimates of $700-$925 per unit. Real rents, leases and tenant payment history decide whether the 7.7% cap is real.
  2. Taxes are unverified The county match failed, so the tax figure in our model may be off. A higher investor tax bill would cut cash flow.
  3. Utility setup is unclear If the owner pays any heat or common electric, expenses rise. Sub-metering needs to be legal and documented.Listing says: “each with sub metered utilities to make leasing units easier”
  4. Systems and building age A 1940 building with a block basement needs inspection of the furnace, water heater, panels, roof and foundation, none of which are described.From photo 7
  5. Priced low with room to negotiate Break-even price is well above ask, so the numbers have some cushion if costs come in higher than expected.

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 407 6TH ST E
  • mediumTaxes and unit count are unverified; no parcel match, so the real tax bill and legal unit status are unknown. Based on: data: county.tax · AI review
  • mediumSub-metering is claimed but not explained. Unclear whether units have separate meters or a billing arrangement, and whether the owner carries any common-area or heat costs. Listing says: each with sub metered utilities to make leasing units easier · AI review
  • lowSeller is a licensed agent, so the listing may be thinly described and sold without much disclosure; verify everything independently. Listing says: One of the sellers is a licensed real estate agent in the State of Minnesota. · AI review

Opportunities

  • 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 $675 vs $800
  • Cheap entry price for three units; a 7.7% cap at ask and break-even price above asking suggest room to negotiate. Based on: data: underwriting.break_even_price · AI review
  • One unit appears to rent below the estimate, so there may be upside at renewal if rents reset to market (no rent cap). Based on: data: rent_estimate · AI review

Questions for the agent

  • What are the current rents, lease end dates and deposits for each unit? Can I see leases?
  • How is 'sub metered' set up: separate utility meters, or the owner billing tenants? What does the owner pay?
  • What are the real property taxes and are there special assessments?
  • Is the property licensed or registered as a triplex with the city, and is the unit count legal?
  • What are the ages of the furnace(s), water heaters, roof and electrical panels?
  • Why are the sellers selling, and what's the vacancy history?

Bottom line

Cheap triplex that pencils at ask on paper, but rents, taxes and utilities are all unverified, so get the rent roll before getting excited. AI-assisted summary
