The right answer is " Sasha will own the house and earn equity as its value increases."
This is probably Sasha's greatest benefit in having a home of her own. After all, after the payment of the financing, the property will be her, constituting a wealth that she can use as she sees fit. She will also have stability not running the risk of having to leave the property, nor submit to the landlord.
In addition, it is very common for real estate to be valued over time. This alone is already an excellent advantage for sasha to opt for home ownership as a safer investment and without so many financial risks.
