Feel free to reach out with any questions regarding flipping or wholesaling 

I'd be open to some consulting to see if I can help streamline what you're working with, however I know when we were at ~15 units, there was no way to justify the cost for something that wasn't lower-end, off-the-shelf software. 

Your cash flow would be $1,000 after all monthly costs if I'm not mistaken.

Now for the good stuff -- my naive proposal. 

They're offering about 75k worth of incentives, and I'm allowed to use that in a variety of ways.I'm lowering the price by 65k, and using the rest towards closing costs so I can have cash on hand for the next property. 

Obviously you will have costs there to pursue it. 

Literally just buying a property costs a bunch of money - more or less depending on your locality and state. 

I don't remember the exact figure, but what surprised us was how similar their cost came to the stick built home we chose.  

I am working with the city for approval and have a cost estimate from someone I know of 250k to build another duplex on the property and eventually multiple duplex.

Building costs here are astronomical.
