There are additional rules for holding it less than 5 years (100% deferred gain recognition), 5-7 years (90% deferred gain recognition), and > 7 years (85% deferred gain recognition).- Any depreciation taken on the investment in the OZ is permanently saved and NOT recaptured if held for 10+ years.

The brokerage seems to be growing rapidly;  can this be sustained in the long run with very little brand recognition amongst customers (compared to a Keller Williams, REMAX, Coldwell Banker etc.)? 

You can use a photo editor to change the pics slightly (I do this too) and not be detected by any image recognition algo AirBNB may use.Require that a license holder reside in the primary residence XX number of days.

This original gain NEVER goes away.Actually, on December 31 2016 REGARDLESS of if the property is sold or not, there is a taxable event of recognition on that original gain. 

If someone is looking down, looking away,etc. with facial gestures as they talk that tends to not be a good sign.

The sale generated the recognition of gain. 

I see some come with a facial, wedding make up business cards to boost their income.

With the Facebook Ads I found that they can help brand recognition, but didn't get many leads. 

There are 4 key dates:year 5 -- 10% step up in basisyear 7 -- add'l 5% step up in basis12/31/26 -- recognition of adj. capital gains as gross incomeyear 10+ -- basis = the price you sell it at

So my suggestion is find the right mix between recognition, money and time that will work for you and interview a few companies.
