I bought a split level house that functions a lot like a duplex so depending on what construction is like in your city that may be an option for you as well. 

Shared bathroom, shared kitchen, different styles, different noise levels.

If you're not doing a high level of volume there isn't any reason to spend the time and energy on a marketing campaign.

I could even go ahead and tackle the debt (which is the option I’m leaning toward) and while I continue to build reserves to a level I feel comfortable investing with, I can try and secure some partnership deals where I bring the deal, and continue to network and grow that way.

Purchasing further away just adds a new level to your overall risk.

So on a national level there is thousands of different ways to do Real Estate Investing. 

@Cory H. another resource would be the county or state level body that governs the installation, use, and service of waste water treatment plants.

As of the 2017 NEC Update, GFCIs are required in all of the following areas:Underwater pool lighting (since 1968)Outdoors (since 1973)Bathrooms (since 1975)Garages (since 1978)Kitchens (since 1987)Crawl spaces and unfinished basements (since 1990)Wet bar sinks (since 1993)Laundry and utility sinks (since 2005)Crawlspaces at or below grade level (2017)Unfinished areas of the basement (2017)

The good news is that Santa Clara County has seen just over 5% appreciation for the same period, so hopefully we align with the county in general at some point this year (Mountain View city level data is prone to large monthly swings due to the low transaction count).
