What are the areas with high concentration of blue collar workers to fulfill the above-referenced projects? 

Thus fulfilling my lifestyle design credentials on wanting to live in an area I like. 

I think a lifelong lesson of mine is to slow down, breathe, trust the process, and take it one step at a time.

I would contend to you his credit probably hasn't changed, and as you have additional deposit, this should probably carry you through to see if he intends to fulfill his side of the bargain. 

My partner has a steady job and indulges my lifelong passion for passive income. 

I would consult with an attorney in your area with a consultation but since she has not fulfilled her end of the deal I doubt she will have any legal recourse.

millennials are just starting to have kids and are going to get to an age where they care about their kids schools etc and it will be far too costly in the city to sustain.so you read it here, mark it down, we are going to see a shift ya the idea that Millennials are going to be lifelong renters in my mind wont come to pass.. 

Beyond that there may be some state/local requirements that you have to fulfill to get the tenants out.  

sell everything and roll it into a small or mid size apartment this is what most that want to be life long landlords end up doing.those that own lots of doors tend to have many paid for in cash..

and your group is all going to be life long renters because you don't want to won real estate and you want to live down town walk to the pubs and resturants.. at least that what people think these days.. and I am sure for a time.. but then life happens.
