How to sell but protect myself from buyer's potential default?

[Ed B.]

I have a house I'm  willing to sell for only $5,000 down (Selling price is $135k), with balance due in 3 years

Other than offering  a lease with purchase option at the end of 3 years, is there any way to protect myself in case the buyer defaults and I have to foreclose?  $5k is not much of a cushion to pay for foreclosure expenses, not to mention lost interest and the aggravation.

Would appreciate any ideas!!  Thank you
