First look

This looks like a single-family house rented by the room to students, not a true four-unit building. The one $1,875 rent is for the whole house, and the photos show one kitchen and a shared living room. The numbers are thin: our model shows about -$4/mo cash flow at the $175K ask, and break-even price is $174K, so there is no cushion. Our four-unit rent estimate doesn't fit this property, so rely on the actual lease. Check the rental license, the lease and the tax bill first, and only tour it if the seller will come down or the single-family resale case is strong.

Things to consider

  1. Break-even at the asking price Cash flow is about -$4/mo at the ask with owner-paid water, sewer and trash, so any repair or vacancy puts you negative. Pricing power sits with the buyer.
  2. Unit count is unverified The county parcel didn't match, and the listing says 4 units where the description reads as a house. Confirm the legal use, the license and the taxes before you trust any figure.
  3. One rent, one lease, until April 2027 Income is a single $1,875 payment, so there is no spread across units. If the tenants leave, the whole property is vacant.Listing says: “Current Lease in place until April 2027.”
  4. License limits the income The city licenses only 4 bedrooms, so a fifth bedroom can't be counted toward rent. Renewal and inspection requirements matter.Listing says: “currently licensed for 4 bedrooms”
  5. Dual-use exit If the rental math fails, a single-family sale or owner-occupancy is a fallback, which limits the downside near campus.Listing says: “potential to transition back to a single-family home once the current lease expires”

From the photos

Listing photo 5
1 of 8Concern

Kitchen has dated oak cabinets, with a gap and scuffed wall near the counter where something appears to be missing. The flooring looks newer.

Listing photo 6
2 of 8Check

Only one kitchen appears in the photos, which supports a single-family layout, not multiple units.

Listing photo 3
3 of 8Check

Living room has hardwood floors and what appears to be a wood stove. Ask about insurance and chimney condition.

Listing photo 8
4 of 8Concern

Bedroom uses a window air-conditioning unit, so there appears to be no central air. The hardwood floors look worn but usable.

Listing photo 1
5 of 8Check

Exterior is gray stucco with a back entry and visible stoops. Stucco and the roofline should be checked for moisture. The roof looks fairly new from the photo.

Listing photo 7
6 of 8Concern

Bathrooms look dated: a tiled bath with older fixtures and a small pedestal-sink bath. Both appear usable but not updated.

Listing photo 2
7 of 8Concern

Yard is open with a rough concrete pad and cracked, worn paving. Good space but the steps look uneven.

Red flags and opportunities

Watch for

  • highRent is a single $1,875 for the whole house, which is low against $175K. Cash flow is about break-even at the ask. Based on: data: underwriting.cash_flow_monthly · 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 511 6TH AVE S
  • mediumListed as a 4-unit in the data, but the description and photos point to one single-family house with one kitchen. Our per-unit rent estimates likely don't apply. Based on: data: listing.unit_count · AI review
  • mediumLicensed for only 4 of the 5 bedrooms. The fifth cannot be rented legally, so income is capped. Listing says: currently licensed for 4 bedrooms · AI review
  • lowStudent-rental wear and tenant turnover risk. The lease ends April 2027, so the next lease-up depends on the school calendar. Listing says: Current Lease in place until April 2027. · AI review

Opportunities

  • Exit as a single-family home when the lease ends. This widens the buyer pool and gives an owner-occupant option. Listing says: potential to transition back to a single-family home once the current lease expires · AI review
  • Detached garage with a loft, plus extra off-street parking, which matters near campus. Listing says: a large detached garage with a loft area · AI review
  • A separate basement entrance could allow extra living space, but only if it is legal and has egress. Listing says: A separate basement entrance adds flexibility for tenants or future use. · AI review

Questions for the agent

  • Who is on the lease: one tenant or several? Is it joint or by the room, and what is the deposit?
  • Can I see the city rental license and the 4-bedroom limit? Is the fifth bedroom legal to use?
  • What are the actual taxes, and what are the water, sewer and trash costs per year?
  • What is the roof permit and contractor for the September 2026 roof, and what are the furnace and water heater ages?
  • Is the basement finished, and does it have egress? What is the heat type?
  • Why is the seller selling, and will the tenants stay after April 2027?

Bottom line

A student-rental house priced for break-even, not a real 4-unit; the case rests on the lease and a single-family resale exit, so the price needs to come down. AI-assisted summary
