Off-Market Deals - Can you get a mortgage?

[Nina Ricci]

Hey guys! So recently, I haven't had much luck stalking Trulia, Red Fin, Zillow, and all that for deals. I've probably seen every listing in the Fishtown/Kensington/Port Richmond area of Philadelphia a billion times.

I was wondering, if I were to start looking for off-market deals, do these deals sometimes allow for mortgages, or is it usually cash only?
