Provided you have a perminent residence status. 

I've read that using social media is important for a business to become visible.

Website, SEO, social media, research, crunching numbers, time to go look at properties/take pictures, call FSBOs, drive for dollars, etc.  

You may find a few pearls but those are far and few between and its great to think your going to fix these social ills one house at a time..

Social Media. 

Often times they will provide a standard form for your current financial status. 

If childless, you would follow the genealogical chart that you'll create up the family tree to their parents (or grandparents) and back down among living relatives.A good place to start is the online social security death index and/or your state's vital records.

For example, if you qualify as a real estate professional tax status, that could affect your strategy.I would not overthink or overcomplicate it.

Social Media- If you have a personal Facebook page, make sure you are posting about your home for sale regularly to create buzz.

I'll be honest that is is often over-promoted here on BP and in many cases an IRA based program is a better fit for an individual situation - employment status, funding source, investment goals, age etc.
