First look

This is a small-town triplex in Maple Lake at $329,900, with 137 days on the market. Our underwriting shows about $686 a month in cash flow and an 8.9% cap rate at the asking price, but that rests on rent estimates of $1,400 per 1-bed unit. The description gives no rents, no lease terms, no utilities and no unit mix, and the county parcel didn't match, so taxes are unverified. Photos show three different interiors with a cosmetic refresh, window AC units and mixed heat types. Ask for the rent roll, tax bill and utility costs first. Then confirm the unit count and the rental license before booking a showing.

Things to consider

  1. Income is unverified The cash flow figure rests on our rent estimates, not actual rents. Get the rent roll and leases before trusting it.
  2. Taxes and unit count are unconfirmed No county parcel match means taxes could be higher than assumed, and the rental legality of three units is unverified.
  3. Unit condition varies Some units look refreshed and others dated, with drop ceilings and window AC. Budget for updates and uneven rents.From photo 10
  4. Basement unit is speculative Converting needs egress, permits and cost. Don't pay for it in the price.Listing says: “with the potential to add a fourth unit in the basement”
  5. Long days on market 137 days suggests the price may be above what buyers will pay. Use it to negotiate.

From the photos

Listing photo 2

Baseboard hot-water heat is visible in this unit. Check the boiler's age and whether there is one for the whole building.

Listing photo 9
4 of 8Concern

A radiator cover with peeling paint is visible in a bathroom, with older vanity and flooring. This suggests an older heating system and dated finishes.

7 of 8Check

Red flags and opportunities

Watch for

  • highNo rents, leases or occupancy are given. The income side is unsupported. Listing says: steady income potential in a welcoming small-town setting · 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 121 1ST ST W
  • mediumBasement fourth unit is only potential. Egress, permits and zoning are unknown, so it adds no value now. Listing says: with the potential to add a fourth unit in the basement · AI review
  • mediumPhotos show baseboard heat, a radiator cover and window AC units. That suggests mixed or aging heating and cooling. Heat type and who pays are not stated. Based on: photo 9 · AI review

Opportunities

  • Long time on market: room to negotiate. Based on: Listing data: 137 days on market
  • Long time on market gives room to negotiate, and the break-even price is well above ask. Based on: data: underwriting.break_even_price · AI review
  • No rent cap, so rents can be reset to market at turnover. Based on: data: underwriting.rent_rule · AI review

Questions for the agent

  • What are the current rents, lease end dates and deposits for each unit?
  • Which utilities does the owner pay, and what were the last 12 months of bills?
  • What is the heat source for each unit, and how old are the boilers or baseboards?
  • What are the annual property taxes, and are there any special assessments?
  • Is the basement unit legal, with egress and permits, or is it only an idea?
  • Why has it been on the market 137 days, and have there been price changes or offers?

Bottom line

The numbers look decent on paper, but with no rents, expenses or verified taxes in the listing, treat the 9% cap rate as a guess until you see the rent roll. AI-assisted summary
