Expanding Tom Au's answer:
"Homosexuality" as we know it is a product of 19th century medical science which ties together a sequence of sexual, emotional, family and social conducts and gives them a new name. We should remember that the conducts we think of as a behaviour "homosexuality" were not necessarily perceived of as a unitary conduct in past societies. That element of theory out of the way:
People who did not marry, and had property to transmit through marriage, would be disciplined by their family or society. This strongly incentivised marriage, and in many agricultural communities marriage was practiced as male to female only. The reasons for male to female only marriage are a combination of reproductive and property based. While he is incredibly out of date in this regard, Engels provides an engaging description of human marriage in Family, Private Property and the State. It is worth it to the extent that Engels notices that the family and marriage are conditioned by other social phenomena.
Marriage was an economic institution (oikos: household). It brought male, female or child labour into the household or established new households. There was, therefore, regulation over marriage and strong economic incentives towards marriage.
Sexual and emotional conduct outside of marriage was often perceived to threaten the system of marriage. In part this is because sexual conduct outside of marriage leads to children, and children can be used to form households. Emotional conduct outside of marriage has been perceived to lead to sexual conduct (even courtly romance notes this), and this can lead to the getting of children. And the getting of children can lead to non-ideal marriages from a property standpoint, or to other problems.
However, sometimes marriage can produce what we now analyse as "homosocial" situations. Monasteries. Warrior cults. Female household networks. Or the structure of the family (patriarchal absolutism say) gave certain people the power to configure permissible sexual expressions outside of marriage.
Also, it is worth noting that officially sanctioned violations of the cultural traditions above existed. Elites often displayed power by violating cultural norms that applied to others.
These complex configurations of gender and sexual expression, when expressed as a continuing culture, can be linked to property. But specific moments have more complex causes than simple one to one links.
The historical position of conducts like forming strong couple bonds, households, marriages, reproductive, economic or sexual relationships are bound up in property, family and gender. Some accounts of post-19th century homosexuality emphasise this in the connection between the "nuclear" family and imperialist capitalism.
