Looking to house hack a Multi-Family, numbers provided

[Albert Gutierrez]

I'm looking at a property where I think it would make financial sense since I could somehow house hack it if the number's make sense and there would be no cash flow (or maybe there would be) and I would skip on paying rent and starting my venture in the RE investor world.

4-plex for 750k  

(All costs per monthly basis)

Mortage $3,402

PMI $451

Taxes $781

Home Owner Insurance $150

Utilities $150

Maintenance and Misc $200

Income from Rent $4,425

Total $709 /month 

Now my question is, I'm planning on living with my girlfriend and splitting the remaining $709 by two, and we are trying to get a conventional loan with 5% down (that is how I calculated my costs) which brings me to the grand total of $355 per month for an asset in Southern California, what do you guys think?

I'm also interested to know the tax benefits, the depreciation of the asset on the tax side and any other benefits that I would gain from this investment, if anyone can input with real world experience on a similar scenario it would help tremendously
