Depends what's important to you. We may have to move to a rental next year and on my list would be: bedrooms a fair way from living room, safe yard for DD, no front steps cos too much hassle with a pram, decent kitchen because we like to cook, good heating and preferably aircon too AND lots of storage. Depending on the layout of the house I may also want a carpeted hallway because I find I'm paranoid about waking up DD walking up and down the house with floorboards. I don't drive so it's also essential for me to be close to public transport and walking distance to shops.

Sometimes it helps to write a list about all the things that annoy you about your current house and then see how the other two compare.
