Hard Money in MD when you already own the home

[Jeremy Paris]

I have a house in Maryland that I just moved back into. My ex got to live in it for the last 3 years under the divorce terms. During that time she trashed it a bit. My realtor tells me once fixed up it will sell quickly because my area is starving for inventory. I got estimates on the fixup needed and am looking at $15-20k. Any suggestions on getting that much money when I already own the house and am living in it?  It's going on the market June 1 so I need to move on it. 

Thanks.
