Most people are refinancing a BRRR because they are in short term debt (like 12 month hard money used for purchase +rehab financing) or own the property free and clear (they bought all cash) and would get a higher return on equity by leveraging the property and reinvesting the cash out proceeds of the loan to scale the portfolio. 

It falls short of the 1% rule which with current rates is not sufficient in most markets to have achieved real cash flow after properly allocating for sustained expenses. 

The property that I have, my family owns is not currently an Airbnb or a short term rental.  

The purpose of marketing is to attract an in-person showing.

This plays into the affordability issues for tenants by allowing them to live in nicer neighborhoods for less money, yet I get monthly revenue comparable to short-term rentals.

Here's what works for me: 1) Posting your property on Facebook Marketplace2) Craigslist3) Talk to local universities or big corporations who may need short or long term housing for their clients4) Property managers are hit or miss.

The older you get the less attractive appreciation is unless the goal is to leave some kind of legacy. 

The higher credit is attractive, but what if the couple's income is 3.2x the monthly rent and the single woman makes 6x the rent?

If you’re looking for short-term cash flow, you might need to explore nearby markets with lower entry costs and higher cash-on-cash returns, even if they aren’t as familiar to you.

I think it's going to be location specific for sure; where I am very few people hang out in the house all day long as they are usually busy hitting the parks and attractions.
