The lease is month-to-month.I’m looking for a recommendation on how to increase the rent.

The building would ideally consist of apartments on the second and third floor with commercial space(s) on the first. 

Inherited tenants increase risk, as they were not screened by you.

I’m 24 years old and when I started was consistently encouraged to buy a home as quickly as possible for specific reasons.

Zillow estimates an 11% increase in home value.

I enjoy my profession but i am very interested in trying to increase income without having to work more.

I have already got notifications from vendors to expect price increases starting Oct 1st, 2018.This will have an impact of all aspects when flipping, renovating and maintaining rentals. 

Focus more on building personal savings and increasing income (is there a possibility of picking up a part time job?)

Once you are certain about the numbers on it and it’s truly a great investment, go back and increase the HELOC you already have and use those funds.

I'm also actively networking with others to increase my funds/passive income by partnering in deals, providing income, working extra, whatever I can do.The point of all this is that I am approaching it like a business.
