How can a girl's father be convinced to facilitate marriage despite the unavailability of a home, when he himself married without a home?

The girl's family should not stipulate that you own a house for the marriage to be complete. It is sufficient that you provide independent housing, even if rented. To convince her guardian, supplicate more often, seek help from someone who has influence over him, and do not mention his previous marriage without owning a house. If the marriage does not materialize, then seek someone else, and fast, for it is one of the best ways to keep oneself chaste. Buying a house is not a necessity that permits dealing with usury.
