Investor on multifamily in bay area seeking advice

[Arthur Yu]

Hi all. I'm a long-time lurker and the real estate books got me onto this forum. 

i'm doing a 20% convention loan on a owner-occupied triplex in hayward(a suburb in san francisco bay area), the cap rate is about 0.04 including the costs to fix the house up front. i'm also including $300/month(please let me know if i am underestimating this) in addition for all the units for repairs etc. 

This is not an area with quick gentrification, nearest BART is 1.5 miles away. So i doubt this will appreciate too much.

Is 4% cap rate in hayward or suburb of bay area worth the hassle of maintaining 2 units worth of tenants? 

Anybody interested, this is the house:
