Also, the revenue estimates are generally widely exaggerated in order to justify the exorbitant property management fees.Finally, if people are interested, I’m happy to post updates on how my own development project works out.I hope this helps!

The need for an LLC is grossly exaggerated on BiggerPockets and other websites.

Crime rates per capita here are pretty exaggerated as a huge chunk of crimes are committed by folks from out of town. 

dollar combined level industry player’s (NAR, lobbying groups, nationwide realty cattle brokerages) imminent death, are greatly exaggerated.
