5000 Square ft Building Orange, TX $500 would you buy it?

[Greg Srader]

I have an opportunity to buy a commercial building on .227 acres of land for $500. The building needs a roof but it is salvageable. The seller is the executor of her mothers will and was ready to sell it to my for land value $3000. I offered to sign a contract and assign, but she immediately dropped her price to $500 Please advise.
