Literally ate Ramen Noodles twice a day majority of a year to save money to invest.

Do that and you will not have any problems.Don't ever miss a payment again.If you can not pay all of September on time I suggest you pack your bags.My guess is your landlord does not know how to evict legally (majority do not) and will likely not be successful.

The city this building is in expects major economic growth in the next decade due to a major factory opening, which should drive up appreciation and rents as well. 

But again, we're not talking about a complex in Denver, Chicago, or any other major market that has significantly higher rents.

Is your major business related?

I think right now there is just this major thirst for doors doors and more doors.  

In my opinion, that will be significant, having two major names (soft-branded) ocean front hotels.  

Another idea I have is buying a SFR with a legal attached apartment and live in the apartment while renting out the majority of the house seeing I don’t need much room.

The house I am currently house hacking needs major work to the siding.

The majority of my rentals are a stones throw away from ASU's Tempe campus, and I've been running that business model for the past 14 years.
