Read these five headline members in order:
Member
What to read
subject_property
Check the resolved house, its facts and their sources.
comp_band
Read the value range implied by recorded comparable sales.
rehab_budget
Check the repair budget actually used.
max_allowable_offer
Read the investor's purchase ceiling alongside max_allowable_offer.clamped.
cost_stack
Read the costs and target profit behind that ceiling.
When max_allowable_offer.clamped is true, no purchase price clears the target margin.
Do not show the amount as an offer.
Successful answers always include subject_property and model_estimate_available.
Other members can be absent; the five headline members are not all required.
Without comp_band, the repaired value, target margin, maximum allowable offer and cost stack are absent.
The captured answer above uses only the address, with a zero repair budget and the default margin.
Its three displayed comparable sales are a retained sample; their count does not reconstruct every aggregate.
