SubForms or Controls

I have a Form with a ComboBox which has a choice of ContractID.

I want this there to be a PropertyID, PropertyAddress (Subform or TextBox??) linked from the Property Table on the same Form which changes when the ContractID ComboBox changes.

I also want a RenterID, RenterAddress (Subform or TextBox??) linked from the Renter Table on the same Form which changes when the ContractID ComboBox changes.

I also want a FinanceID, FinanceName (Subform or TextBox??) linked from the Finance Table on the same Form which changes when the ContractID ComboBox changes.

Is it best to have different SubForms or is it easy enough to have TextBoxes inserted on the Form (maybe via a Query)?

Text Boxes would be my preference, I think.
