Developer wants to buy my property

[Laurent Vincent Walker]

Hello Everyone,

A few years ago I bought a fixer upper home for 250k. Homes fully renovated around me go anywhere from 400-650. Bought the home to be my forever home because I have strong roots here and my family is already. A developer approached me because I am very close to everything. There is even commercial across the street. I am up for selling if the price is right but I really don't know what to ask for. I am expecting a low ball offer shortly. Looking for target prices,questions I should ask him ect. 

Thank you in advance.
