First look

This is listed as a duplex, but the description reads like a single-family sales pitch and gives no rents, no unit split, no heat type and no utilities. At $500K, our numbers show about -$753/mo cash flow and a 4.6% cap rate, with break-even near $359K, so it doesn't work as a rental at today's rates. The photos show only one kitchen and one laundry set, so confirm there are really two units, and whether it's licensed as a duplex. The lake access and Mahtomedi schools support value, but that is a lifestyle premium, not rent. Don't schedule a showing until you have a rent roll, tax bill, and confirmation of the unit layout.

Things to consider

  1. Price is far above what rents support Our estimates of about $1,775 per unit give a cap rate of 4.6% and about -$753/mo at asking. Break-even is near $359K.
  2. Unit count and legality are unverified We couldn't match a county parcel, and the photos show only one kitchen. If it isn't a legal duplex, the income case falls apart.
  3. No rent or expense information The description gives no rents, leases, utilities or heat details, so every income number here is our estimate.
  4. Dated kitchens and baths They look original, so budget for updates if you want to push rents toward the high estimate.From photo 5
  5. Shared lake dock Lake access drives value but isn't income. Terms and costs of the shared dock need checking.Listing says: “lake access to White Bear Lake and shared dock”
  6. 1901 build with updated electrical claimed Old houses can hide wiring, plumbing and foundation issues. Verify permits and get an inspection before relying on the updates.Listing says: “updated electrical throughout”

From the photos

Listing photo 5
1 of 7Concern

The kitchen appears dated: oak cabinets, laminate counters, and a basic electric range. The tile backsplash looks like a recent cosmetic touch.

Listing photo 8
2 of 7Concern

Both bathrooms appear original or builder-grade, with older vanities and tub surrounds. They're functional but dated.

Listing photo 3
3 of 7Plus

Carpet and fresh white paint look newer, and the windows appear to be updated double-hung units. The interiors look clean and move-in ready.

Listing photo 9
4 of 7Check

The basement has an exposed electrical panel, a dryer vent, and what appears to be one washer and dryer set. Check the panel's amperage and whether laundry is shared or per unit.

The exterior shows gray shingle-style siding in decent shape and a small front entry. I only see one front door, so confirm how the second unit is accessed.

6 of 7Check

The garage or basement space appears to be unfinished storage with painted block and wood paneling. I can't see parking or the building's condition.

Photos show only one kitchen, and none show an upper unit, the roof, the heating system or the new deck. Ask for a complete set.

Red flags and opportunities

Watch for

  • highMarketed as a lifestyle home, with no rental details at all: no rents, leases or expenses. Listing says: Don't miss your chance to own this incredible lakeside retreat, book your private tour today! · 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 60 GROVE ST
  • mediumLake access is via a shared dock, so rights and any association fees or rules need verifying. It may not be exclusive or transferable to tenants. Listing says: lake access to White Bear Lake and shared dock · AI review
  • mediumSat on market 61 days at $500K, yet the numbers are far below break-even, so there's room to negotiate. Based on: data: listing.days_on_market · AI review

Opportunities

  • Lake access and Mahtomedi schools could keep tenant demand strong and help resale value. Listing says: Located within the award-winning Mahtomedi School District (#832) · AI review
  • No rent cap, so rents can follow the market after any updates. Based on: data: underwriting.rent_rule · AI review

Questions for the agent

  • Is this legally a duplex, and is there a rental license? How are the two units laid out, and are there separate entrances and meters?
  • What are the current rents, lease terms and tenant move-out dates? Can I see the rent roll?
  • What's the heat type, and who pays heat, water and electric? Are there separate meters?
  • What are the real property taxes, and are there any special assessments?
  • What are the shared dock terms, fees and rules, and may tenants use it?
  • How old are the roof, furnace, water heater and electrical panel? Were the electrical updates permitted?

Bottom line

A lakeside duplex priced like a lifestyle home: at $500K it loses about $753 a month on our numbers, so it only works well below roughly $359K. AI-assisted summary
