My plan is to BRRR after the 3 years at school left and invest in one or two houses a year by working full time job as a civil engineer and invest in apartments.

- I could pay cash - assuming this would improve my chances at best offer. 

Get a job.

But, even though I own another home besides this one, make a mid-six figure income and have excellent job security (cybersecurity), and a DTI ratio of 13% - I can't qualify because my FICO score (612) is too low.

I contacted the Realtor and asked what improvements have been made, and if the current month-to-month tenants are able to move out by time of possession (I dont want to inherent tenants).  

Personally i'm looking for buy and hold opportunities but i work a full time job and know i couldn't do it on my own.  

, (2) completes the job on time and on budget, and (3) does a good job.

My main job is an Advanced EMT for the county.  

And of course, I would like to improve my ROI.I am willing to take action as needed, but not until I am ready.

Great job on your first flip!
