Usually, this would include something like a holding company ("Hold Co"), typically a traditional LLC, which in turn then owns an investment entity, often a traditional or Series LLC, which will be the entity that owns the assets/property invested into (the "Investment Co").

Yeah you won't get the tax benefits that trickle down to your personal income but that's because in a retirement account there are NO taxes on the gains in a Roth or it's tax deferred in a traditional.  

Depending on the types of repairs needed you may or may not be able to get a traditional mortgage for the property. 

I don't know if this is the case but I also think operators use the fund of funds model to bypass the 506c accredited investor requirements.

Others specialize in buying rentals using traditional 20% down methods. 

This can be particularly advantageous for those in need of quick funds or looking to steer clear of the strict criteria set by traditional lenders.

Well, for $1000 I only take home additional $12.5 (half of the mostly usual 2.5% comp for my market for the sake of argument with a traditional broker).Clients think somehow each agent is making %5-6%, in their pocket, for each transaction. 

What you’re getting at is that when you lose your W2 it significantly worsens your debt to income ratio – which would make getting traditional loans harder.

I second Don and Chris.Hard money lenders are typically able to approve much faster than traditional financing due to the fact that most of their underwriting is based on the asset--in this case, the house. 

The unfortunate reality is that the national average is around 28k for hairstylists.I own my own salon suite, and believe it or not it's the most money I've ever made in my career so going back to a traditional salon is not an option I plan to pursue.I was planning to so a small multifamily (duplex or triplex), live in one side and rent the other out (my boyfriend would also be paying me rent as well).There is no shame in what you earn!
