3 Unit Property, ? worth buying

[Scott Malkin]

Hello, new to this, first time posting, curious what everybody thinks about this investment:
- 3 unit property in San Diego
- current rents are 2400 +2400+1200 = 6000, sought after location, easy to rent
- purchase price $800k
- 1920's property, well-maintained/upgraded, no obvious initial work/repairs needed, has potential for historic designation/ Mills Act thereby reducing taxes
- while financials may not be ideal as solely an investment property, also considering possibility of living in one of the units for a while
- if owner-occupied I can purchase with 5% down, ~ 4.5% rate with no pmi...

Thanks, looking forward to everybody's comments!
