No cash flow but equity, Is this ok?

[Saemi Jung]

I am looking to invest into my first tri or quadplex to start off my REI.

Since I want to buy a property in CA with less than 20% down (VA loan, no house hacking), I was just looking to build equity on the property even if it doesn't give me any cash flow first few yrs.

Is this ok? Or should I look for a different route? 

Also, is it bad manners to talk to multiple real estate agents? I heard this from a friend. 

Any advise is appreciated :)
