How do I find GCs that will work within an investor budget?

[Viet Hoang]

I'm looking for a general contractor in Jersey City, NJ to do a full gut renovation for a 707 sqft rental property.

How do I get "Investor Pricing" vs "Retail Pricing" from GCs? The bids I'm receiving vary wildly.

Bid #1: $95k (includes materials and labor) 

Bid #2: $60k (includes ONLY labor)

Bid #3: $30k (includes materials and labor but has inconsistent quality and reviews)

Thanks!
