Frequently asked questions

Does the bank really allow two families on one loan?

Yes — though some lenders find it harder than couple co-purchases. Joint and several liability means each family fully liable for the whole loan if other defaults.

How is ownership split?

Per co-ownership deed — typically proportional to deposit and ongoing payment contributions. Tenants in common with specific share percentages.

What if one family wants to sell?

Deed should specify exit — buy-out by remaining family at agreed valuation, or forced sale. Without deed, exits messy.

Can FHB Guarantee apply to two-family co-purchase?

Generally no — scheme designed for individuals/couples. Two unrelated families typically can't use FHB Guarantee jointly.

Are halal options available for two-family co-purchase?

Yes — Diminishing Musharakah structure naturally fits multi-party. Some Australian Islamic providers structure for two families.
