Say that $500k is invested in a new trade or business - now it is business interest expense. 

If you're more of a 'personal referral' person than a 'do research online' person, and this is local to you in Manhattan, KS, hit up one or two of the trades people in the "little apple all stars" BNI group.

I’m new to the community and I’m planning to start a Section 8 rental property business.

I'm a rookie in whole selling , I only have the knowledge that social media has and I think I understand how it works but have no idea of where to start or how its pretty frustrating not being able to provide for my family the way I want to and I could really use some advice or maybe tutoring in this subject, I just turned 20 and I want to have a good life in this economy I could really use any advice thank you so much.

I would tend to agree with the other CPAs typically.The 500-hour test is one of seven material participation tests used by the IRS to determine if a taxpayer is actively involved in a trade, business, or rental activity. 

Sure, they may be able to grow to a very moderate size,  add a few units, or trade up to a larger investment, but as for real scalability: NO.Why?  

You don't have a recourse because you took the liability on yourself knowing that is not his trade.  10 days later you have a water leak in the SAME bathroom causing the ceiling downstair to leak AGAIN.  

So it all starts with yourself and your spouse first.

Starting all over from scratch... my gray hair is turning back black....LOL.   

Day traders are not exempt unless they elect mark-to-market (MTM) accounting, which eliminates wash sale tracking but taxes gains as ordinary income.To manage taxes, track trades closely, avoid overlapping purchases, or consider MTM election if trading actively.
