There are some great resources already in here (@Tanner Lewis is great and so is Avery at the Short Term Shop). 

Live in the hipster Roosevelt district and can target struggling artist types, Tempe college students etc? 

Is this syndicator hitting targets or not?  

The Bigger Pockets community and podcast has been a major resource and mentor in helping me learn the ropes of real estate investing. 

On top of that, I watched Zach and Rick’s videos, which are great resources and completely free.

I tried getting heloc from my large bank, However I was denied due to my income. if you can't get the credit lines for some reason from your bank then they have resources for that, even their own cpa you can use for a fee.

Why not just target $600k buyers in general?  

The BRRRR method and house flipping are both fantastic strategies, especially if you're resourceful and willing to put in the work.If you’re working with limited capital, partnering with others or exploring creative financing options like private money lenders or seller financing might be worth considering.

I’d have to pay the full class in order to be done but I owe so much on it and their rebuttal is that I’ve already been exposed to the resources and tools that they offered so I guess I’m stuck with them till I pay it off.

Is there a target cap rate you are going for?
