@Hannah898 great question! Agreed with
@Ilene795 that understanding the underlying worries your husband has is important.
Another key step is to talk through feasibility/timeline of moving closer to your parents. If you realize that's something you want to do soon (i.e. in the next five years) then the significant costs of buying and selling a home may not be worth it.
However, if you're committed to staying long-term (5+ years), I agree with
@Terry846 that now is an excellent time to look given historically low mortgage rates. NerdWallet has a good
buy vs. rent calculator that can help you understand (at a high-level) how long it may take you to earn a positive return on buying a home.
