@Ashly McGlasson - First, congratulations to you and your husband for achieving as much as you have. One successful flip and a 2nd house renovated and on the market is not a failure by any reckoning. I would venture that most who try REI never get as far as you two'
The problem may be that right now instead of having the worst house in a great neighborhood you have one of the better houses in a poor (or better stated small) neighborhood.
Is your agent advertising outside of your local area? The Midwest is considered an investable locale these days due to the price inflation on either coast. Make sure that your property is being marketed to catch the eye of buyers relocating from higher-priced markets so that the size and amenities of your property seems more of a bargain. Ask your agent about the feasibility of marketing to businesses that may be moving employees around or need short-term residence for visiting executives.
From your post it does not sound as if methods such as lease option or out-and-out rental would work as you want to free up your money. The classic plan if you intend to pull out of the market temporarily is to drop the price by a significant percentage when you re-market at a later date. Again, this may not work for you.
I assume that the "hot" selling months for IL, as in WI, are May through August. If you pull out of the market now are you prepared to have the property sit for 6 or 7 months? If so, your current listing contract may have expired and you could try FSBO to save a bit on commission. Not knowing your asking price I have no idea if this would be a meaningful saving.
I know my suggestions are of limited help. I hope some of the more experienced BP members will weigh in.
