TaxesCash flow is controversial: your business needs cash flow to survive, but the source does not matter, could be your W2 if you have one.

Well said.Much of running any business is common sense.

Also bear in mind @Limor Hanannia that if the IRS thinks you're running a business within your SDIRA or Solo 401k you will be taxed on UBIT for that as well which scales up to 37% so it can be quite hefty. 

I have been a General Contractor in the San Antonio area for the last 16 years and now looking to grow in this new face of business.

In a similar fashion, if you can imagine how much landscaping and underground infrastructure is in a golf course as compared to the clubhouse, that will give an indication of why an extremely high percentage of the property's value is allocated to the land improvements.

Hey Richard, We operate a few small business in the Real Estate Investing space hear in columbus from Acquisitions and General Contracting through to the sales department and Custom Construction.

How good is your business plan.

It's all apart of business!

I am good at what I do, lead generation and seo..But I SUCK at running a business.

@Nathan EmmertHow do you feel about using separate properties as "different businesses"?
