Investment-property loans

Business underwriting for income-producing property, and why occupancy must be honest.

Direct answers

An investment-property loan finances an income-producing condominium or house at a higher rate under business underwriting, and it is commonly recourse — model vacancy, rate resets, and exit, and never use an owner-occupier loan instead.

Key points

  • Business underwriting at a higher rate than an owner-occupier loan.
  • Japanese loans are commonly recourse unless the documents say otherwise.
  • Model vacancy, negative cash flow, rate resets, weak resale, and exit.
  • Never finance a rental with an owner-occupier loan — misstating occupancy is fraud-adjacent.

Business underwriting

An investment-property loan finances an income-producing condominium or house and is underwritten as a business, at a higher rate than a consumer owner-occupier mortgage. Investment-loan rates are frequently quotation-based and property-based rather than publicly advertised. Crucially, Japanese loans are commonly recourse unless the documents expressly say otherwise, so a shortfall after a sale can follow you personally. Underwrite the deal on net operating income, DSCR, vacancy, and a realistic exit — not gross yield — before you rely on it.

Occupancy must be honest

The most important warning is that you cannot casually convert an owner-occupier mortgage into an investment loan. Moving out, long-term renting, Airbnb use, or running a business from the property may breach loan, insurance, building, zoning, or condominium rules, and misstating occupancy can trigger decline, acceleration, fraud concerns, and insurance or tax consequences. If the plan is to earn rent, use an investment-property loan from the outset and keep occupancy statements accurate.
