I know someone recently who had a NY loan and they could not find a servicer to touch it because it was being self serviced - so they had no way of selling it as no investor would take on that risk.The other concern is usury laws.

I self manage 29 SFR and do all my taxes on turbo tax.

Housing lots/ subdivision, self storage, commercial, parking, rv park,  etc3.  

The shameless self promoters are gamblers, narcissistic, and constantly chasing the next money making scheme.

Perhaps I make 5-10% if forced to sell if I’m lucky, break even at worst.2) I’m VERY glad I chose to invest in my local market (and not OOS), because I know which neighborhoods to buy in, and I also can self manage, which saves a ton of money and I am able to develop local connections, which helps me buy at a discount.

Primarily self limiting beliefs.One of my clients just closed on their first commercial deal and they only had one duplex before I started working with them. 

The last one we paid cash for and self-funded the improvements too.

When you transfer retirement funds into a self directed account you can certainly buy real estate with it. 

There are always some self-righteous individuals who try to appear as very professional figures in this community. 

You're in the business of flipping houses, so any self-employment taxes on the ordinary income most likely aren't being calculated in QB.
