New roof, which remediate the mold issue, $8,500.Countered seller with: fixing foundation issues, splitting roof cost, evicting hoarder.Seller in turn countered with $8,000 credit, to use as we see fit.Rents are below market and there's room to raise them even before rehabbing the units.Tear me apart.

Assuming you sell for $300k, of which $100k goes to pay off your debt, you could use the remaining $200k in equity for down payments of approx $25k each (25% down can get you better interest rates), giving you 8 cash flow properties which would be paid for by tenants by the time you really need the income (retirement) and provide moderate rental income in the meantime.You'd have to be able and willing to take on that much debt, of course, (so your debt-to-income ratio, annual income, credit score, etc will all impact this).

Thanks everyone, but the renovation part of this is 98% done, with still a little room for improvement... which is my downfall because I keep thinking of new ways to keep pouring money into this thing, and I gotta stop that.I've broken up my story because I have a thousand progress photos.So why don't I continue.....Ah, the photo is right side up.So that chair and the metal desk came with the house.

Any lenders or referrals to obtain a line of credit on Jersey City NJ rental property--2 family house. 

I'd talk to some credit unions around you locally.
