A 15 year mortgage payment for a decent 3 BR home would be about 28% of her net income. A 30 year mortgage would be about 22% of net. She has no other real expenses other than food and gas.
Assuming she will live there at least 10 years:
Scenario #1: If the BF lives with her, I say "no". The reason is, I don't think it is healthy for one unmarried partner to move into another unmarried partner's owned home (just my opinion, from experience). The partner who does not own the home never has a stake and things tend to get "sloppy". The partner who owns, subliminally always thinks "I can always boot him/her out..." If they live together, rent or buy a place together and not with grandma's money. They need a written cohabitation agreement spelling out all financial and household responsibilities. If it's a community property state, they need to consult an attorney.
Scenario#2: She lives in the house without BF and plans on living there 10+ years. OK, even though she's not very "financially thick".
Overall, home ownership, especially with a one person household, is not vital. The cost of housing is mostly correlated with square footage, especially in the "21st century". Ownership anchors SOME of the costs, not all.
