@Joe Villeneuve I am not arguing with the power of leverage. 

We do all the work ourselves- from plumbing to siding to electrical.

Chimney liner recommended for $2,000We found an additional $2,000 of electrical work was neededOur lender suddenly informed us that there was a cap on seller concession towards closing of 2% of selling price.

They also need to understand that they will be throwing away any money spent on kitchens and baths down the road when they update the plumbing/electric. 

Added master bedroom, walk in closet, master bath, generous laundry/mud room and electrical closet.

The tenant responds she intends to pay, but had lost her job and has to pay for food and electric, etc with nothing left over.I sympathize and at the same time want to be paid. 

Do they have any decision-making power or involvement in the process?

Water, sewer, gas, electricity.

How do I contact local electricity company to increase one more meter on three existing meters?

(small electrical updated needed) I am refinancing my first duplex to pull cash out for this down payment.
