Megan, finding any RENT TO OWN in this hot market is almost impossible. Unless they are going to scam you. Just wait, pay your bills on time and in less then a year you can qualify for a FHA loan. Talk with any lender and get on a plan to get a FHA loan. There is no such thing as credit repair either, don't waste your money. However, its your money. http://www.tcrdallas.com
If by "second chance" you mean you have bad rental history or credit, be aware in this area most landlords are very strict with whom they accept. Someone may accept your application, but will ask for a double or triple deposit amount. Best of luck in your search!!
