First look

Two of three units are vacant, so the real income today is one lease at $1,300. The other two are only asking rents ($1,600 and $1,100 with all utilities included), and those are projections, not income. Our underwriting at asking price shows about -$32/month cash flow and a 6.3% cap, which is thin and leaves no room for surprises. The county parcel didn't match, so taxes and unit count are unverified. Check that first, then the rental license, the heating setup, and why two units are empty on a listing called 'well-maintained'. Worth a showing only if the license and taxes check out and the price comes down.

Things to consider

  1. Only one rent is real Two vacant units mean income depends on leasing them at asking rents. Underwriting assumes full occupancy, so cash flow is already negative and would be worse until they fill.Listing says: “Unit 1 is currently vacant and being marketed for rent at $1,600 per month”
  2. Owner-paid utilities cut into thin cash flow Heat, water and electric on two units can eat a large share of rent. At about -$32/month cash flow, any utility bill makes the loss bigger.
  3. Taxes and unit count are unverified No county parcel match means the tax figure in our underwriting could be off. A higher non-homestead bill would cut returns further.
  4. Old building with visible exterior wood stairs Stairs, porches and a 1905 build usually mean upkeep costs and inspection items. Budget for repairs and reserves.From photo 1

From the photos

Listing photo 1
1 of 8Concern

Large wood exterior staircase and deck serving upper floors. Appears weathered; check for rot, railing and code compliance.

2 of 8Check

Kitchens appear dated, with oak cabinets, laminate counters, vinyl floors and drop ceilings, but they are clean and functional.

Listing photo 3
3 of 8Check

Cast-iron radiators in rooms and baths indicate hot-water or steam heat. Likely a boiler; confirm whether one system serves all units.

Hardwood floors and bay windows in the main unit appear to be in decent shape.

Listing photo 7
5 of 8Concern

Bath finishes appear dated, with a basic vanity and a shower with a plastic or glass enclosure.

Listing photo 8
6 of 8Plus

A second kitchen with a separate entry door suggests a separate unit; this supports the unit count.

Listing photo 1
7 of 8Check

Gravel parking area at the rear is visible. There are no photos of the basement, laundry, boiler, electrical panel or roof.

Listing photo 10
8 of 8Check

Windows appear to be older single-pane or replacement units of mixed age. Check energy efficiency, since the owner pays some utilities.

Red flags and opportunities

Watch for

  • highTwo of three units are vacant, so only one rent is proven. Asking rents of $1,600 and $1,200 are unverified. Listing says: Unit 3 is currently vacant and being marketed for rent at $1,200 per month · AI review
  • highOwner pays utilities on at least two units. With a radiator/boiler building, heat could be a large cost, and no utility costs are given. Listing says: Unit 1 is currently vacant and being marketed for rent at $1,600 per month with the owner paying utilities · 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 1511 4TH ST E
  • mediumUnit 1 asking rent of $1,600 is well above our $1,300 mid estimate for a 2-bed, and it includes utilities. Based on: data: rent_estimate · AI review
  • mediumPhotos show a wood exterior stair and deck structure that carry safety and maintenance risk. Based on: photo 1 · AI review
  • lowListing says 'well-maintained', yet two units are empty. Ask why. Listing says: This well-maintained triplex offers an outstanding investment opportunity · AI review

Opportunities

  • Long time on market: room to negotiate. Based on: Listing data: 27 days on market, 2 price cuts
  • Vacant units can be delivered with fresh paint and set to market rent, or you could occupy one yourself. Listing says: offering an excellent opportunity to secure a new tenant at market rent or occupy the unit yourself · AI review
  • Shared basement laundry behind a coded entrance is a useful amenity. Check whether it is coin-op for income. Listing says: shared access to a full basement with laundry facilities accessible through a secure coded exterior entrance · AI review

Questions for the agent

  • Why are Units 1 and 3 vacant, and how long has each been empty? What did they last rent for?
  • What are the trailing-12 utility bills, especially heat, for the units the owner pays?
  • Is the rental license current for three units, and when is the next inspection?
  • How are the building heated and metered? Number of boilers, water heaters, and electric meters?
  • What are the real property taxes and any special assessments?
  • What is the age and condition of the roof, the exterior stairs and the panel wiring?

Bottom line

One proven rent, two vacant units and owner-paid utilities make this a thin deal at asking; verify the numbers and negotiate. AI-assisted summary
