Financing House Hacking

[April Littleton]

Hi I am new to real estate investing and wanted to know how to go about a couple things when house hacking. 

1. Do I need set up a business first (i.e. LLC)?

2. My dad is retired military so he qualifies for a VA loan. How would I go about using his loan to finance a multi-unit? Would he have to be the home owner and responsible to live in one of the units?

3. How do I incorporate renovations into the budget? Should I renovate one unit at a time then post to rent or wait til all units are ready? 

Thank in advance for all the advice it truly means a lot to me ????
