Anecdotally, it sounds like a mixed bag.

According to the City planner, there is no immediate impact to the current construction/units according to the city but this could be developed in the future for mixed use.We have no experience in commercial so any input would be great .

In the end, the strategy is to do a mix of all three.

I have mixed feelings about them as do many seattlites,  but generally speaking they are more organized and better managed than the currently available alternative  (tents,  broken down RV or cars,  or piles of cardboard)   ---   I'd trade a larger tiny house village  for an equal reduction in the number of "unsanctioned" campers in an equal radius of my home  (and investments)  any day.That said,   I do disagree with the "low barrier" ones (which allow drug use/etc). 

I have a situation where I would like to open a self directed IRA and have contacted a few of the online players and am getting a mixed message, some say it's possible some say no way Jose'.  

This is a good reason to avoid mixing business and pleasure. 

When we start to build a portfolio, then look to bring a management co in the mix. 

Very eclectic and energized in many directions.

I have read mixed opinions about that strategy.

I believe the seller can pay back the owed amount for a period of up to ( now here is where I have mixed information and I have not taken the time to verify) 1 or 2 years.
