Mililani is a really good market, so getting a fixer upper property at a low end will be harder.

I invest in mid to upper-income areas where good credit scores and high earners aren't hard to find. 

I would then plan to use this forced equity (since I plan to buy a fixer upper) to invest in another home.I have been constantly reading to househack right into the MFH, but this may take some time for me to acquire the money and purchasing power.

They buy homes in upper middle class to lower upper class neighborhoods which represent solid appreciation potential and reasonable upkeep/taxes/insurance expenses.  

Instead of chasing the latest hot market, focus on investing where you have the upper hand—where you have a deep understanding and local knowledge.

The good neighborhood, area around OSU, upper Arlington, Dublin, etc, are pretty expansive now.

The ground floor is occupied by a commercial restaurant, and the upper floor is designated as SRO (Single Room Occupancy) under a pre-existing non-conforming use.

Not only are prices being pushed and dragged down on all middle and upper inventory, but you can get seller finance 1,000x easier than it's been in literally 30+yrs.
