If you are serious about investing then you should definitely get an LLC to protect you and your assets BUT do that in conjunction with implementing all your marketing.You have nothing to protect if you never get a deal.

My goal is to obtain passive income through multi- Family rentals.

I have made the decision to obtain my preapproval upon arrival back in the states and start my search for my first house hack at that time.

Here’s the stats - -$500 to activate line (credited back if deal closes in 90 days) 
- 3.5 % origination fees 
- Close to 10% rate 
- Each project is reviewed/underwritten by FoA, which could take up to 30 days 
- Up to 90% acquisition & rehab, I believe 
- Standard draw rules on rehab side - Line is up to 5x of assets, equity in home, 401k, etc- Line has to reset to zero once per year
