Wow, can't add much about the finanaces as I'm not very knowledgeable about that end of things.
The advice I would give is this (based on my experience of house selling in the UK):
If you are looking to sell your house, make sure that any work you spend money doing will actually add to the value. Ground wiring is a must. BUT: Tiling the kitchen and other cosmetic work is unlikely to add any value to your home, although it would make it easier to sell if it looks nicer. So don't spend a fortune on purely cosmetic stuff because you might not make back what you spend - investigate what improvements would actually add significant value before embarking on any projects. Upgrading your central heating for example may add to the value.
