I am having a free first time home buyer lecture this Saturday at the Glenwood Springs Library and I think it may help to answer a lot of your questions. It's at 10:30 am and brunch will be provided, you can reserve your spot and find out more on this site http://homebuyersbrunch.instapage.com/ Feel free to call if you have any questions! I hope to see you there :)
You are among many in this situation, this is more prevalent in this market but your options are limited. Hire a good real estate agent and ask them to search "lease-to-own, owner carry and lease option". You will have to discuss the terms with each owner to see if you can align agreeable terms. Good luck, give me a call if you have any more questions.
