First, your credit score is better than you may imagine. Generally, a minimum 620 credit score is necessary to buy a home. Although there are some additional factors, you're already in a better position.
Now, to determine your options on selling, I would need to valuate your home and compare it to activity in your immediate area. If you'd like, I can prepare a discreet and FREE home valuation for you. Simply go to http://www.syan.com/valuation and input your property information.
What specific problems are you having with the HVAC and electrical system? Also, have you had the roof looked at to determine if a patch will resolve the issue or if the roof needs to be replaced? Every home has a buyer, even homes that are in need of repair. These type of issues can always be negotiated with a buyer.
Is renting an option or selling with owner-financing? Do you have money saved for a down payment?
There is much to discuss. Feel free to connect with me.
