I'm currently under contract for a wholesale flip where things are starting to look a little bit tighter than I initially estimated.

FWIW I bought from a local supplier who also did the installation, and paid just under $4 sq/ft. 

Are you including cleaning of common area, repairs, pest control, and landscaping under maintenance?

Heck, I was selling 2-3 flats 12 years ago trying to convince investors that it's was a great idea when prices were under $150k.  

Hi BP community, I need some advice on what approach I should take in order to get this property under contract.

CEO of Zillow's personal home sold for 40% under Zestimate.

She actually told me that our bank loses money on every mortgage originated under 50k, however they are required to underwrite every loan despite the size.  

If they own several they are obviously investors.Once you get a response from the seller of the vacant house, negotiate a deal to buy it for all cash and get it under contract.

So I have two properties under an LLC that are free an clear and I would like to use them as a collateral and like that make sure of excess cash to purchase it   any Ideas on type of loan options?

I pay $500/transaction under $100k and 1% at $100k and over.
