RentOMeter.com can give some good estimates as well, but it's definitely worth it to check all the sources you can.

I'm embarrassed to admit I actually hopped on a plane from San Francisco after work one night last month gleeful at the chance to buy a turnkey for 40k that was worth 50-55k (what Clayton talked to me about as the usual scenario)! 

I did get a call from a neighbor that they saw racoons going into the house, and in Google earth view, there was a tarp on part of the roof. 

As Nick mentioned, you always want to verify their previous work and view.

The shed will be a long term property asset so installing one might be a worth while value add. 

I would be interested to see what you think from an adjusters point of view on this. 

I figured that was worth the extra cost.   

@Juan Francisco yeah that makes sense actually...if the situation is the seller needs to get rid of the property or face being bankrupt then it it worth the shot for then to do a subject to type of deal 100%

- Level of prescreening performed on buyer before they can view the property- Who is best fit to handle the coordination of the showing, contracts, and closing? 

The seller needs to come to terms that it isn't worth what he wants, he has to take a haircut to sell it.
