I chose to invest in 1272 Lakins Rd, Etna, due to its potential in a growing market.

This signals long-term appreciation potential.

It was in response to a potential emergency situation (ex: a water heater in one of my units was leaking and they paid a little over $2,000 for replacement).

What's the condition, what's rent potential, is it in appreciating or depreciating area? 

The strategy I'm following for my first house hack is to acquire a multifamily property (duplex, triplex, quadplex) or SFH w/ an ADU (or potential for an ADU) as I am mainly looking to simultaneously acquire my first property and subsidize my mortgage payment.

A small multifamily property is a smart choice for a first investment—it offers a great balance of income potential and manageable scale for someone new to the space.Don’t worry about being ambitious; it’s clear you’ve done your homework, and you’re already ahead of the game by setting a clear goal.

Pensacola is a great market for investing and the number of properties available right now is up so there are actually some on market properties with potential. 

Due to high premiums, expenses increase, and cap rates and cash flow potential decrease.

If anyone tells you that you can get 15% cash-on-cash it's either a scam or ultra high risk. 

But if you get a major expense you could then potentially have a decent amount of debt.
