First look

This is a construction project, not a rental. The duplex is stripped to the studs with no finished kitchens or baths, so the only income today is the small house next door. Our 6.9% cap rate and $98/month cash flow assume both units are finished and rented, which they are not. Budget for a full build-out plus carrying costs for months with one tenant paying, and get contractor bids before anything else. After 222 days on market there is room to negotiate, but verify permits, zoning and the single-family rent first. A showing only makes sense if you can price the finish work.

Things to consider

  1. The duplex produces no income until it is finished You carry the purchase and construction costs with only one small rent coming in. Our cash flow figure assumes a completed duplex.Listing says: “The unfinished duplex has already been taken down to the studs with demo complete”
  2. Construction cost and timeline are the real price Full interiors, systems and exterior finish on about 2,900 sq ft can be large. Get bids before offering, since the $229,900 ask only makes sense with those numbers.From photo 10
  3. Underwriting rests on estimated rents Our estimates are for finished 3-bed and 2-bed units. The listing gives no actual rents and no county record was matched.
  4. Zoning and permits need confirming Mixed-use zoning may help, but the legal unit count and approved plans decide what you can build and rent.Listing says: “the property is zoned Mixed-Use”
  5. Long time on market gives leverage 222 days suggests few buyers can make the numbers work. Use that to negotiate.

Red flags and opportunities

Watch for

  • highDuplex is unfinished. No income from it until completed, and cost and timeline are unknown. Listing says: The unfinished duplex has already been taken down to the studs with demo complete · AI review
  • highUnderwriting rents and the 5 bed/2 bath figures can't be verified. The duplex doesn't exist as finished units and no county record matched. Based on: data: underwriting · 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 2502 3RD ST W
  • mediumCurrent income comes only from the single-family rental, and its rent and lease terms are not stated. Listing says: Next door sits an occupied single-family rental providing immediate income · AI review
  • lowMixed-use zoning is unverified and permitted use is left to the buyer to check. Listing says: buyer to verify intended use · AI review

Opportunities

  • Long time on market: room to negotiate. Based on: Listing data: 222 days on market
  • Build out two finished duplex units plus the existing house for three income streams. Listing says: the property has the potential to generate revenue from two duplex units plus the existing single-family home · AI review
  • Seller has had it listed for 222 days, which gives room to negotiate on price. Based on: data: listing.days_on_market · AI review
  • Layout plans are provided, which could shorten design and permitting time. Listing says: Layout plans are available in the photos and supplements · AI review

Questions for the agent

  • Are permits pulled and open for the duplex work? Any inspections passed, and who did the work so far?
  • What is the single-family rent, lease end date and deposit, and does the house have a rental license?
  • How many units is the duplex legally approved for, and what does the mixed-use zoning allow?
  • Do the plans include engineered drawings, and what is the seller's cost estimate to finish?
  • Do the house and duplex have separate utilities, meters and heating systems planned?
  • Why has it sat 222 days, and have there been price cuts or failed offers?

Bottom line

A stripped-down duplex shell with one small rental next door: only worth it if the price covers a full build-out and months of carrying costs. AI-assisted summary
