That depends on how much and what types of 'decoration' you are interested in. If you like what model homes typically use to decorate, than if you find one, that may work. Limiting yourself to model homes will reduce your choices in other criteria because you just won't have that many to choose from.
Regarding 0-5 year old homes, that is ok. However, builders typically 'upgrade' their homes based on communities, so actually searching certain communities that match your 'level' of decoration may tailor your search more effectively. Remember that in any given search with criteria of age or community, you will have some well decorated homes, and some not so well. You will just have to set up a search and see what you find.
You mentioned renting out your other property. Do you need to obtain a mortgage for the new house? If so, you may want to contact a lender to review your situation. Many lenders nowadays are requiring a 2-year rent history if they are using the rent payment as income on your loan. If you need a referral I give you several. I can also run a search for you with a given criteria. Let me know if I can help with a referral or a search of homes (or anything else).
