Make a list of everything you need to buy / have done , get an approx cost for the whole lot , and start triaging !! As the previous poster says as much as it would be great to have everything straight away , theres no point getting into debt for it .
Gradually go through the list and eventually you will come away knowing what essentials you must have, plus take help from friends / family who offer painting services , know how to lay floors , have a suite of furniture theyre getting rid of ( it may not be to your taste but it wont be forever ) etc etc .
Bear in mind the cost of repaying your 30k CU loan on top of your mortgage repayments , repayments on a eg - 10k loan would be more manageable, you'd have you the essentials done.
Make sure you have something to cook with , sit on , sleep on - if you really think about it the paint , tiles, wooden floors , blinds etc etc are not absolutely essential .
Very best of luck !
