You land costs are $160k, demo assume $20k, that puts your total costs around $1,140,000, with income of only $7,200 per month ($86,400 per year).  

I'm in the middle of demo and getting major system repair quotes.

There is a mortgage, a second investor loan and monthly payments to the city (demo lien-?)

@Sammie Yang Welcome to Bigger Pockets.  

@Ching Yang, If you reword everything in terms of "act of service", you will be looked upon differently.Wholesalers enable quicker access to capital through a network of buyers to motivated sellers, without having to fix up the houses, that traditional MLS or retail buyers cannot provide.

The Township claims they have no records or any documentation regarding the demo, but I have proof that they oversaw it and paid for it.Basically, I'm trying to do some "digging" to see how long the Township has been polluting this lot and covering it up (literally and figuratively).

You will need to do some selective demo to open up the area in question to get to the root of the problem. 

Expect to come out of pocket $15k+ to renovate 4-5 homes to the point they can be sold.On your two that are unlivable, you can usually get a roll off dumpster and demo them in place.  

 Some progress pics.Fireplace was removed, I had decided to reface it, but upon demo sheetrock underneath was damaged.This added about 4X8 to the  room!
