First look

This is a Mankato up/down at $194,900 with a 1-bed upper rented at $925 and a main floor that last rented for $1,670. Our underwriting shows about $401/mo cash flow and an 8.9% cap at ask, which is decent, but it rests on unverified taxes because we couldn't match a county parcel. The owner pays gas, electric and water/sewer/trash for both units, and with 100-amp service and what looks like a single set of mechanicals, that is a real expense drag if not metered. The main floor is vacant at 77 days on market, so check why and what rent it can really get. Worth a showing if taxes and the utility setup hold up.

Things to consider

  1. Owner-paid utilities Gas, electric and water for two units can eat several hundred dollars a month and may not be fully reflected in the cash flow.Listing says: “Owner pays gas, electric & water/sewer/trash.”
  2. Taxes unverified We couldn't match a county parcel, so the tax bill is a guess. An investor may pay a higher non-homestead tax.
  3. Main floor rent is a past figure $1,670 is what it last rented for, not a current lease. Our mid estimate is $1,775, so the upside is modest.Listing says: “It was last rented for $1,670 per month.”
  4. Basement bedroom legitimacy The fourth bedroom drives the 4-bed rent estimate. If it is not legal, rent may be lower.From photo 9
  5. Recent roof and exterior New shingles and replaced siding lower near-term capital needs.Listing says: “New shingles fall of 2023.”
  6. 100-amp service A single small service for two units may limit capacity and could need an upgrade or insurer review.Listing says: “100 Amp service.”

Questions for the agent

  • Are gas and electric separately metered for each unit, and what were the last 12 months of utility bills?
  • Why is the main floor vacant, and why has it been listed 77 days?
  • Is the basement bedroom included in the rental license, and does it have a permitted bath?
  • What are the actual property taxes, and is there any special assessment?
  • What is the upper tenant's lease status and term?
  • How old are the furnace, water heater and electrical panel?

Bottom line

Reasonable-looking Mankato up/down with a recent roof and decent numbers, but verify taxes, utility costs and the basement bedroom before getting excited. AI-assisted summary
