Hi,
You could try to sell it at breakeven price. Mortgage plus all expenses. But, the biggest problem is that even if you get an offer for full price, if buyer requires financing, appraisal might show a lower price.
In FHA financing the sales price is protected and if property doest not appraise sales price, purchase contract is canceled.

In a conventional mortgage, lender, to my understanding, will lend under the appraised value not under the sales price.

Another option is, set it at current market value and bring the difference at closing so credit is not damaged.

It seems that the smaller one is a rental, check with your accountat the tax repercutions of selling such property in Short Sale, wich is your last resort. It might show up on credit report as a foreclosure.

Keep asking questions!

Benito.
