First look

Two units at $850 each is $1,700 a month, and our model shows about $98/month cash flow at the $165K ask with a 7.1% cap rate. That works on paper, but the taxes are unverified because we couldn't match a county parcel, so pull the real bill first. Rents sit below our mid estimates ($1,000 for a 1-bed, $1,075 for a 2-bed), so there is some upside if tenants turn over. The listing also says the sewer line was replaced in 'September 2026', which is odd for a listing dated April 2026, so confirm the date and get paperwork. Photos show a dated basement and no exterior of the roof detail, so a showing looks worthwhile only after you see the rent roll, leases and tax bill.

Things to consider

  1. Taxes and unit count are unverified Without the real tax bill, the cash-flow estimate could be off a lot. Taxes on a non-homestead rental can run higher than the seller's.
  2. Rents are below market At $850 each, the units rent below our mid estimates, so there is upside on turnover, but only if the units can support higher rent.Listing says: “Each unit is currently rented at $850/month.”
  3. Month-to-month upper tenant The upper tenant can leave on short notice, so plan for turnover and vacancy after closing.Listing says: “The upper unit is currently on a month-to-month lease.”
  4. Heat and utilities are not described A single furnace in the basement suggests shared heat, which could mean the owner pays for it and cuts into cash flow.From photo 10
  5. Long time on market 167 days gives you leverage to negotiate and ask why it hasn't sold.

From the photos

Listing photo 1

Exterior is vinyl-sided with a newer-looking wood front porch and asphalt shingle roof that appears in decent shape; there is no close view of the roof.

Laundry hookups with a dryer vent hose appear to be on the main floor, which seems to conflict with the description saying laundry is in the basement for the upper unit.

Basement has exposed wood joists, block walls and a forced-air furnace and water heater; the furnace appears older. A single furnace suggests shared heat.

  • mediumSewer completion date is in the future relative to the listing date; verify the work and permits. Listing says: Exterior sewer line replaced and completed September 2026. · AI review
  • mediumShared laundry is in the basement serving the upper unit; unclear how the main unit does laundry or whether the heat and water heater are shared. Listing says: The unfinished basement provides shared laundry for the upper unit · AI review
  • lowMonth-to-month tenants can leave quickly. Count on turnover soon after closing. Listing says: "garage. The upper unit is currently on a month-to-month lease. Exterior sewer line replaced and completed September"
  • lowMain-level unit has street parking only while the upper unit gets the garage; check how that affects the lower tenant and rent. Listing says: front entry access and convenient street parking · AI review

Questions for the agent

  • Can I see the rent roll, signed leases and the last 12 months of expenses?
  • What are the real property taxes, and is the property licensed as a rental?
  • How is heat supplied and metered, and who pays for it, water and trash?
  • What is the sewer work date, and can you share the invoice and permit?
  • Does each unit have its own electric meter and panel?
  • Why has it sat for 167 days, and have there been price cuts?

Bottom line

Fully rented, cheap duplex with rents under market and positive cash flow on paper, but verify taxes, utilities and the odd sewer date before you trust the numbers. AI-assisted summary
