Now of course, you have different classes of apartments in different locations which have an influence on the type of good it would be considered (ie college apartments, blue collar/working class, upscale, etc) Normal goods in my book to name a few would be retail centers (which typically take huge hits with economic downturns, especially without large anchor tenants), smaller or single tenant office properties, and warehouse/industrial properties (with highly leveraged tenants with tight margins running on leveraged A/R and inventory). 

I just graduated from college as a biomedical technician.

Our long term goal is to use it to pay for our kids' college.

We have 10 units (5 properties: 4 in Escondido, one near Mesa College).I am also new to BiggerPockets but we have been investing in real estate for 12 years (purchase to rent with positive cash flow) and my Mom did it when I was pre-teen and her estate (my step Dad) still owns and rents some of those properties. 

I have been interested in real estate for some time now but have been focused on getting my wife through college for the medical industry.  

Therefore, we have similar income and similar life timelines such as college for the kids, retirement, etc. 

Some background: I am a recent college graduate from the Silicon Valley who just started working full-time in Seattle, Washington in Software Engineering.I'm new to this business, so I don't really have a specific long-term plan as of now.

I just graduated college last year so the biggest roadblock for me currently is having very low capital to invest.

Last time I expressed doubt about the magical properties of single member LLCs of the sort most members here are setting up, Jerry W. accused me of wanting to deprive landlords' kids of their college funds.
