not enough room to even do cosmetic and rehab so along do major rehab and hold for 4 to 6 months and sale....The answer remains unknown.

Also, you can simply not answer the phone for unknown numbers which is what I do most of the time now.If you want to get off the phone really quickly, here is another way. 

Although there are risks in all deals, having too many unknowns in a common agreement (ie: option price, date you can exercise the option), does not seem worth it. 

If unknown, does it seem to track Zillow, for example?

@Jennifer Fernéz The truth is, there's too many unknowns to advise you.Zillow, Realtytrac, etc. are worthless when it comes to comps.

Lawyers are trained to think in abstract terms and deal with issues referred to as "life events" and "unknown unknowns".

Regulated or registered lenders don't have the issues that private investor/lenders have.Financing then goes much deeper than drafting an note that is agreeable between two parties and the unknown, unknowns will determine what may be safe, predatory, intentional, lawful, enforceable or prudent.  

That's great advise for both sellers and buyers since it removes many of the unknowns from a deal.

you are not part of the case....you could possibly file motion to intervene, have a judge listen to you and allow you to move along with your plan... to me there are a lot of unknown...dont have that much gamble in me ...

Anytime you can net healthy profit and remove unknowns and liability that's a win in my book.
