We already own a primary residence and vacation home, so this will be seen as an investment property. 

@Michelle Nevarez, the most common way people get started is through house hacking.You could use your VA loan to buy a property for yourself to live in.  

Looking for some guidance from either property management company owners/brokers or landlords that have 100+ units managed through property management software such as Buildium, AppFolio, Propertyware, etc.. 

I'm wondering if any veteran on BiggerPockets has ever utilized their VA loan to secure any multifamily property ( specifically here in Los Angeles County), i'm familiar with the process but just wondering if anyone has ever done it.

It's pretty unlikely that you'll hit FI in 5 years unless you have paid off properties.

Real Estate investing and management of all my properties is all I do.

Investing in buy and hold properties here in Washington has been very rewarding for my wife and I. 

My duplex units are almost identical.Also, after sold, my understanding is that, I can purchase only non owner occupant property via 1031 exchange, but I can purchase either owner or non owner occupant property via Sec 121 exclusion.

Property needs some fixing, but I think has potential (especially in our highly inflated housing market).

Lower property taxes and landlord friendly.
