It has 11 studio units at 200sqft which I think is tiny, but apparently they are renting well.

I actually built my own tiny cottage house with mine own two hands and have deconstructed a 500sq ft studio for the material.   

The ones I've seen, such as some of my tenants, are living together with everyone contributing toward the household.

The right lender might allow you to get a tiny bit of cash out of that property, or, more likely cross-collateralize it as part of another loan.

It is a tiny book with a huge message.

We're going to guess what the income tax rate for a 120k household is going to be in 20 days.

It's like betting on Germany to win the world cup after they decimated Brazil, the odds aren't good anymore, yeah you might make a tiny bit of money but everyone who bet prior to the Brazil game is who is getting rich. 

A few examples off the top of my head are prices ending in 999 or 444, houses with the number 7 in the address, phrasing when listing a property and the corresponding sale price, etc.I think these are fun things to look at but I don't think they should carry too much weight when it comes to acquisitions, although they are definitely signs of a more affluent and stable neighborhood...just my .02 I think what's great is knowing that companies spend a literal ton of money on location research, they are doing our work for us to know what average household income is, what disposable income is, and they do a lot of footwork in location, location, location.  

For REI, we are starting out with a vacation rental, a tiny house which will be located on the farm property, but we hope to also move into buy & hold.I am also concerned with asset protection for our land if someone were hurt here.

Average household income is 44k (http://en.wikipedia.org/wiki/Corpus_Christi,_Texas).
