Quote from @Raj Patel: Added commentsMixed Use: - Longer vacancy times - To get a tenant, you may pay a LOT in TI (Tenant Improvements) - You may be less likely to get in a lawsuit, but if you do get into one, you may be in a fight with a sophisticated business owner, not an unsophisticated individual.
