We have been blessed to serve a a ton of Bigger Pockets clients and the biggest challenge we have with house hackers is the FHA Self Sustainability test.. 75% of the overall rent has to cover the PITI.. with rates where they are this has been a big challenge. 

The biggest problem I see with syndication deals is that you have to put $50K + per deal.

As for the cheaper markets, I would look to do mid term rentals in the Rust Belt near hospitals like the Cleveland clinic to maximize the income to help mitigate the downsides and unexpected expenses associated with those markets.

The only downside is the time difference when its 11am in NYC, its 11pm in Manila. 

Note this is the biggest issue, but other things to consider is no revenue until ADU is built and rented.  

We've found it has superior reporting features, integration features, and is overall more efficient to work within than other REI-specific software.The downside is QBO is not set up for REI so you'll need to do that or work with an expert to ensure it is set up for your business appropriately.Something else to keep in mind is your entity structure and how your entities file tax returns.

.: Quote from @Joe Fish:Long-term fixed rate debt and quality location are arguably going to be the biggest two biggest hedges against the play against infrastructure and land.  

I've never had a tax sale turn out to be void, but it is my biggest fear with Alabama tax sale investing.

Goal is to reduce your biggest expense (housing) with income coming from the ADU to save money for your next RE purchase.

You will get the biggest tax bang for your buck if you purchase by the end of 2022, but that should not be your sole criteria for the purchase.
