First look

This looks like a cleanly renovated duplex, but the price is the problem. At $615K and our mid rents of $1,950 per unit, cash flow is about -$1,354 a month and the cap rate is 3.7%. Break-even is near $361K, so the ask is roughly $254K above what the rents support. The year built (2003) doesn't fit the description's 'new roof and siding' and the older look of the house in photo 1, and the county parcel didn't match, so verify the year built, unit count, taxes and rental license before anything else. Worth a showing only if you want to owner-occupy, or if the seller comes down a long way.

Things to consider

  1. Price versus rent math Negative cash flow of about $1,354 a month at ask and a 3.7% cap rate. It only works with a big price cut or owner-occupancy.
  2. Unverified records Without a matched parcel we don't know the real taxes, unit count or rental license status. Taxes could move the numbers further.
  3. Rents are a wide range Our estimate runs $1,225 to $2,700 per 3-bed. Actual rents decide whether this is worth a look, so get the rent roll.
  4. Renovation quality and permits Cosmetic updates can hide old systems. Confirm permits for the work and the age of the mechanicals.From photo 2
  5. Owner-occupant angle Living in one unit can allow lower-down-payment financing and offsets cost, which may suit this better than a pure investment.Listing says: “Whether you're looking to owner-occupy while generating rental income”

Finishes look like a rental-grade cosmetic refresh. Vinyl plank flooring and basic fixtures are durable and cheap to maintain, but verify permits and the quality of the work behind it.

Exterior shows new-looking vinyl siding and a dark shingle roof. Some moss or debris appears along the front roof edge and the roof line looks uneven.

Questions for the agent

  • What are the current rents, lease terms and are the units occupied?
  • Is the property licensed as a rental in Saint Louis Park, and is it legally a duplex?
  • Who did the renovation, were permits pulled, and what did it cost?
  • What are the real property taxes and are there any assessments?
  • Are heat, water and electric separately metered for each unit?
  • Why is the year built 2003 if the roof and siding are new, and what is the true age of the structure?

Bottom line

Nice-looking renovated duplex, but at $615K it loses over $1,300 a month as a rental, so it only works as an owner-occupant deal or at a much lower price. AI-assisted summary
