If you planned on moving out of a house and buy another property, as an example, you could pull a HELOC before you moved out and keep it as an emergency fund.  

For example, what is the current zoning - does it meet your needs?

Search the BP for ADU appraisals to encounter numerous examples.

For example, learning how to navigate CRMs like HubSpot or property management platforms like Buildium could be a big plus.

Quote from @Zach Howard: Hi, I'm researching financing options for non-US citizens who wish to purchase multifamily investment properties - around 4 units to start with, for example. 

Flipping it will take time if you have to sell.Plus a home like that doesn't lend itself to a LTR unless there is a demand for high end rentals.What I would like to see is some examples of what you are looking at along with basic numbers you have run so far.

Send me a PM and I'll send you a couple of examples of what is on the market outside of Atlanta so you can run your numbers and see if that fits.

For example Intel headquarters, Google, FB, Amazon, Nationwide, Honda, (recently Anduril announced another 4k jobs to Columbus).

Example, buying a vacant lot from a neighbor and simply explaining that someone else will be on the contract in a few days is not easy.

An example was a line item for alimony (I am single and have never been married).
