You have asked two different questions. First you said you need to "sell your home quicikly", and then you asked about renting it. You will more than likely find a tenant quicker than you will find a buyer, and then you have to wait for the buyer to get a loan approved. ( 4 to 6 weeks, on average.) So, it depends on what you mean by "quickly".
But you didn't say you needed to move OUT quickly; you said you need to SELL it quickly. Two entirely different things. One brings the equity into play, while the other one brings a monthly cash flow into play. You will need to decide which is more important to you.
The speed at which any given home will sell will usually depend on 3 things: Location, Condition, and Pricing. You obviously can't change the location. You can make the house sell faster if you improve the condition, especially cosmetics. And, if you price it below average for your neighborhood, it will sell quickly at this time of year.
The Bottom Line is: You need to contact an experienced Realtor to come over and evaluate the property for you. Writing questions on a website like this one isn't going to get the job done for you. You should select an Agent you want to work with, and then have them come by and inspect your property. Then, sit down and discuss your options. Some houses are selling within a few weeks; others may take a few months.
Please let me know if I may be of further service.

Rick's answer is spot on. Rent to own almost never works out in the tenants best interest. If you are able to buy then you should speak to an agent who can set you up with a solid lender. They will walk you through the pre-qualification process.
If you need to lease while your credit improves there are a lot of wonderful properties that you can look at. Keep in mind, while Rick states credit is an issue with renting as well, proof of income and a solid rental history are far more important.
If you have any questions I would be happy to walk you through your options. And don't ever pay an agent for their time. Commissions are built in to contracts that are paid on the sellers side 99 percent of the time. Don't get tricked and don't ever work with an agent that you don't feel has your best interest in mind.
