It's really a personal choice.

Nasdaq would be my top choice but S&P 500, Wilshire, etc. would be other fine choices. 

If possible, I would say it's going to be most beneficial to house-hack in most situations.

All you can do is make the choices that stack success in your favor. 

I Typically talk to people about real estate who will benefit from the conversation or can create mutually beneficial relationship from it.  

Good luck on whatever choices you take.

I am certainly not endorsing this as something I would personally necessarily support, it's just the way stuff like this has panned out in the past... we have a Supreme Court that for over two centuries has acted wildly beyond their explicit constitutional mandate [sometimes in really beneficial ways], we have a Fed, etc.

In the end, it is your choice.

You also need to consider the ramifications that a bad tenant choice will have on your other presumably "good" tenants. 

I also realise that stocks take alot of effort and research to understand how the company is doing and the status of the markets in which they operate.Ultimately it's up to personal choice and results are based largely on duediligence.
