Broker info & key considerations To confirm

Legalization lead · income and margin unproven

Obtain permit/code records, a written legalization plan and authorized inspection access before estimating an offer.

  • Buyer is to assume open permits, violations and compliance costs for the additional unit; no legalization determination or cost estimate has been obtained.
  • No interior access is offered and occupants must not be disturbed. Current condition, leases and delivery terms are unverified.
  • The $3,650/month claim includes an unpermitted unit without a rent split or leases. Whole-property income and NOI remain unknown.
Source evidence and diligence

Financial figures observed Oct 20, 2026. Reported income is not audited collections. Editable estimates, financing and saved assumptions are separate from these source facts.

Gross rental yield basis

Needs supported whole-property rent or your rent assumption and a positive asking price. Unknown rent is not zero.
