Drawbacks to 1 bd/1 ba units to consider even if meet %, #'s?

[Shannon Tennyson]

Very new to REI. Looking at a 1/1 condo near a univ campus that generates 7.5% CoC and meets 1% rule (1.5%) for under 50K. Wondering if worth considering based on analysis, or whether there are other risks or drawbacks for condo/small units that I should consider. Analysis includes mgmt fees, 4-5% cap/repair, HOA & 3-4K rehab at purchase. Any thoughts or experience with small units that might help in my decision? Ty in advance.
