First look

This is a nice-looking Grand Ave up/down, but the numbers don't work at $530K. Our rent estimate is about $1,775 per unit, and the underwriting shows roughly -$1,452 a month and a 3.1% cap rate. Break-even price is around $257K, so the ask is far above what these rents can carry. The description gives no rents, no lease terms and no expense history, so ask for the rent roll and leases first. The listing also says nothing about heat, and the county lists central air with water-based radiators visible in the photos, so confirm who pays what. St. Paul's 3% rent cap limits how fast rents can rise to close the gap. Only worth a showing if the seller is far below ask or you're buying to live in it.

Things to consider

  1. Price far above what rents support Underwriting shows negative cash flow of about $1,452 a month and a break-even price near $257K, so there is little room to make this work on income alone.
  2. Rent growth is capped St. Paul limits increases to 3% a year for sitting tenants, so you can't quickly raise rents to close the gap.
  3. High property taxes The non-homestead tax bill is large relative to likely rent of about $3,550 a month combined.
  4. Licensing needs clarifying A duplex should hold a 2-unit license, and an expired or mismatched license can cause fines or block rent collection.
  5. Rents and utilities are unknown Without a rent roll or utility responsibility, cash flow can't be verified, and owner-paid heat would worsen the numbers.Listing says: “Both units are currently rented, providing immediate rental income and added peace of mind for investors.”

  • Both units have the same layout, with a den that adds flexibility to attract tenants Listing says: an adjoining office/den offering additional flexible space · AI review

Questions for the agent

  • What are the current rents, lease end dates and security deposits for each unit?
  • Who pays heat, water, electric and trash, and are there separate meters?
  • Is the property licensed as a 2-unit rental, and why does the city record show a 1-unit license that expired?
  • What are the $432 special assessments for, and will the seller pay them at closing?
  • How old are the roof, boiler, central air and electrical panels?
  • Do the tenants plan to stay, and when did their rents last change?

Bottom line

Attractive, well-located duplex, but at $530K the rents cover only about half the cost, so it only works at a much lower price. AI-assisted summary
