Can This Be?

[Michael Barido]

I'm interested in a Class C, 27,000 sqft building in a down town area (population near 50k) that is owner finance. Terms aren't 100% but thinking $220k (full asking), 30 yr amortization, 6% rate, 10 yr balloon, and 10% down. It is 100% leased with a local hospital's plastic surgery center, a financial business, a physical therapy business, and one or two more businesses. Leased amounts total $35k/m at NNN (so advertised) but not sure how that works with multiple tenants. Building purchase price is $2.2M. Cash flows per my tough calculations are $9k with full gross lease and $15k with NNN. Does this make sense. Let me know if additional info is needed.
