First look

This is a 1915 Waseca duplex of two 3-bed/1-bath units at $149,900, and our numbers look strong on paper: about $510/month cash flow and a 10.5% cap rate at asking, with rents estimated near $1,250 per unit. But those rents are our estimates, since the listing gives no tenant rents or lease terms, and we couldn't match a county parcel, so taxes and unit count are unverified. It has sat 311 days, which usually means a reason beyond price. The photos show an older building with grassy overgrowth, dated baths and some scuffed walls, and the basement, kitchens and roof were never shown. Get the rent roll, taxes and an inspection before deciding. It's worth a showing if the taxes and rents hold up.

Things to consider

  1. Rents are our estimate, not actual Cash flow of $510/month rests on estimated rents of about $1,250 per unit. Actual leases could be lower or higher, so get the rent roll.
  2. Taxes and unit count unverified No parcel match means the tax figure in our model may be off. Taxes can swing cash flow noticeably on a $150K building.
  3. Long time on market gives leverage Nearly a year listed means the seller may accept a lower offer. It could also signal condition or tenant issues.
  4. Building age and exterior condition A 1915 building with weathered siding, foundation staining and a rear stair may need near-term capital spending. Budget reserves.From photo 2
  5. Boilers described as updated, but unverified Heating is a major expense in Minnesota. Confirm age, one boiler or two, and who pays for heat.Listing says: “updates including updated boilers and PVC for the sewer system”

Questions for the agent

  • What are the current rents, lease end dates and deposits for each unit?
  • What are the annual property taxes, and is the duplex licensed as a rental in Waseca?
  • Who pays heat, water, sewer and trash? Are there separate meters for each unit?
  • Why has it been on the market 311 days, and have there been offers or price cuts?
  • How old are the boilers, roof, electrical panels and windows? Are there permits for the work?
  • Do the units have separate gas and electric meters? Any history of water in the basement?

Bottom line

On paper the numbers are strong for Waseca at this price, but rents, taxes and condition are all unverified, and 311 days on market begs the question why. AI-assisted summary
