Due to my lack of experience, I have a hard time accurately plugging in numbers such as closing costs, fixed/variable expenses and any necessary repair costs, although I have connected with a couple contractors to help with that.

Impossible to accurately predict.

Is this an accurate understanding?

The most accurate place for comps is Realtor.com

Nothing you wrote is accurate other than your first sentence, that being that yes, you can sell a home before the foreclosure auction.

Any insight on if Im computing the number right or accurately would be GREATLY appreciated!

For context, a quick background.I’m 23 years old, just graduated from college, making 45k a year (going to be relatively open here about finances because I want the most accurate feedback)I have about 60k in student loans that I’ll have to start paying back in December.

We routinely see bad bookkeeping, questionable (or optimistic) rent rolls, and all manner of numerical freewheeling in financials, so make sure the numbers are accurate, and then, check again.  

Still higher than the 3.75% I'm paying now for that $73K, but not much of a gamble.2.

I was really accurate with my rehab costs despite the things that go wrong, but not as accurate as I expected with my ARV.
