You do have another possibility. Depending on where the home is you're looking to buy, you might be able to arrange for an exchange. You trade your property here for the property there, maybe in Streamwood, Hanover Park or Hoffman.
Of course you would want to know first how much your property here is worth so that you could find comparably valued properties in the target area. Then focus on properties there that are looking for an exchange in Fort Worth or that might be.
While the likelihood that you can match up is not 100%, it is worth a try, especially if your credit won't allow you to purchase.
If you can get an equity loan on up to 80% of the value of your current home, you could generate enough funds to buy something there or at least have a healthy down payment that you could use to convince the seller there to hold a second mortgage for the balance.
Feel free to contact me if you have other questions.
