Help in Analysis of a potential assignment

[Tracy Sharpe]

I am not sure if I analyzed a particular deal and wanted some feedback.

I know a person who has a house valued at $152,000 according to Zillow. He owes $77,000 on his current mortgage. I am estimating $20,000 in Rehab. Additionally, the seller wants $30,000 for himself. I want to walk away with $5000. I am calculating $10,000 for the investor. What should I offer the seller in order to meet the requirements of this transaction. I used the flipper calculator but I am not sure if I did it correctly or even if I know what I am doing. The house is located in Texas, Denton County. Please provide feedback.
