In most markets that can legally have STRs and that the local government embraces, you can get up to 50% more in rental income vs traditional rentals. 

Might be a good place to look also if you find yourself frustrated with the high price/rent ratios in the residential sector.

It can be done but your getting into state and Federal laws governing securities.

I didn't join the military largely because I wanted to be able to carve my own path and also be paid a competitive salary as military doctors are capped at a little over $100,000 a year(whereas in the private sector as a psychiatrist I can make 200k-400k if I really hustle and don't mind moving to find a high paying job), but not having any debt is huge.

Exactly this.Just as some love what they do and want to w2/1099 or would love to go back, true investors aren't limited to just landlording on the RE side, nor are we limited to one industry sector or vehicle in general. 

I think of DFW the same but not as many O&G companies and a bit more heavily toward the financial and technology sector. 

One of the tenants is a problem tenant, and on on government assistance. recently she got in an altercation with one of the other tenants causing them to break their lease and moved out.

Curious what the stance is of government entities in each market in California.

Although we can't be for certain on the payment history of the the tenants, we did find out that one tenant has been there for 13 years (unit B) while two tenants are getting their rents heavily subsidized by the government (I might add unit C is abandoned but the government is paying the rent until the lease is over in a few months or so I'm told and unit D is the one being evicted - he hasn't paid his portion).

@Imthiaz Ahmed The 4-unit limit is I believe a Fannie Mae and Freddie Mac limitation: http://www.freddiemac.com/singlefamily/news/2017/1128_loan_limits.htmlAnything beyond that, and your investment is no longer backed by the government, which is why you can get the lowest rates on conventional loans (i.e. less risk).The question to ask yourself is, is a commercial loan all that bad?
