But beyond that he always closed, not contingent on finding a buyer at a higher price.To me there are but two ways to operate as a wholesaler ethically, honestly and legally (one way may require licensure depending on the state the property is located in).  

An inspection contingency allows the buyer to exit the deal if material defects are found. 

Jazz - make the sale contingent upon rent being paid or them moving out.MichaelIf you have an attorney, and you should have, check with him/her.

We should of at least had a contingency for it.Now that my first flip is over, I am really excited to keep this going and am currently looking for my next house.

My ideal criteria includes: 1,200 - 1,500 sqft, 3 bed, 2 bath, garage (contingent on elevation), and bullet proof.I have seen some listings for somewhat odd and overgrown parcels of land selling low where the numbers might work quite well.

Remember that like most of these sites, the data may be stale.It depends on the seller whether they want no financing contingencies or if they're flexible.It depends on whether you can get the info a lender would need to go in to closing with a loan commitment.

In institutional real estate deals, financing contingencies almost immediately eliminate the bidder.

What I do is submit my plans to them to be permitted while I am still in the contract phase of a land acquisition, and I make closing on the land contingent upon being approved for my intended use.  

The contingency inspection was sufficient for me as a buyer. 

Thanks @Amy Osterberg, @Shirley Gregory, and @Michael Goodman -- appreciate the welcome from the NC contingent here at BP!
