re: Bond for deed - bad idea?

I bought my first house bond for deed. Wife and I were young and had some credit,but not enough. Put $15,000. down on a $65,000. dollar house. Three years later Metairie bank was able to lend us the money to pay off the bond for deed. The key to this working is they have to have a lot of money to put down or I would not consider. If the buyer has no skin in the game, it makes it very easy to just walk away just like they were renting from you. Think of a number that makes you say,I don't care if they walk away. My two cents, good luck.
