My properties are in locations with high rental demand so I know even in a bad market I can easily cover my debt service and other expenses. 

That means the rental income covers the associated mortgage PLUS the cash that exceeds the mortgage and expenses helps pay other debt

. $60k loans are possible, as long as you can qualify with your down payment, debt ratio, and credit.

Unfortunately, I am up to my neck in student loan debt - however, my dad offered me a position this November making $100k+ guaranteed...but it would require me to move 8 hours away from my wife and our friends and the place I am establishing my roots for our future.In your experience, would you recommend I do this for a year or two, pay off our debt and get some capital in the bank BEFORE I begin investing?

@Michael Lee unfortunately owc is a no go, as he is cash poor, and badly in debt.

I have no debt and a credit score of 686 (Was a 740 but due to fraud on a store cards it was maxed out which effect my score).

@Rhett Z Begley Sure you just need to match the debt on the new property you purchase.  

If I dive into it a little bit, we know that banks don't really want to be buyers and sellers of real estate but if you have paid off most of a property (say 50%) and you foreclose or for some end of the world reason, the bank calls you to pay off your debt now and you can't they can profit more on the resale of your property once they foreclose.

Seller’s Debt-to-Income cleared of the mortgage 2.)

Your main costs will be Property Tax, Property Insurance, Maintenance (small repairs, landscaping, pest control, etc), Capital Expenditures Reserve aka Cap Ex (money set aside for roof, HVAC, Flooring, etc), Vacancy, Property Management, and then any debt service you have on the property.
