I am about to close on a home that is no where near my design taste, but I wont have a cash to do any big items to change it more to my style. Its pretty as is, but so far from what I typically like that I just cannot imagine how to decorate this room. What couches should I get? Where do I put the couches? can I put a TV somewhere? RUGS?! I don't even know where to start with a rug. Can I add color to the walls?

Someone with a better eye than me, please help!
