In my entire adult life, I have never experienced a 3 bedroom house that would rent for as low as $1300/month.

These are people who have lived in the homes basically all their adult lives, and as such, have accumulated "stuff" that is difficult to part with.

Two unrelated adults rent the house with two children.

Good for you that you are already scared to be dependent on a employer.Out of college and working at a good day job I had many memories etched into my mind of grown adults being terminated in 2007 and no backup plan.

In my city, you cannot have more than 3 unrelated adults living together.

Past trends regarding older generations have usually seen young adults, primarily in mid-twenties, buy bigger homes which are more focused on family building, since millennials are shifting away from these past trends and wanting to live in smaller homes there has been a high demand for said houses.

Im going to live with my parents as long as they will let me for free, so I can save as much as possible and have a running start being a "full time adult"

All of my adult working life I've been stuck and complacent in the customer service/retail/sales industry (not the rewarding kind of sales).  

So my wife and I have been negotiating with a home owner for about 2months now and this is our final proposal that he has agreed to:Property is worth 640k with current adult family home set up or 690k when fixed up without the adult family home equipments.

That need and a little prodding by my older brother, who is 62, and has most of his adult experience in construction and offered to be my partner.Now, let's get to you.
