How long to modernise house?


It all depends on how much needs to be done are rewiring/replumming involved?
If it's only cosmetic work involved then the revamp should be quite quick.
If it's a major renovation then I'd say depending on funds give yourself a year of getting jobs done one after the other and you'll get there.

Helpful parenty advice:

Rome wasn't built in a day.
Give it time and money.
You've all your life to do it.

and so on and so on...

Good Luck
 
It took me 3 months for major house renovations and another 3 months to finish it - painting, landscaping, carpets, curtains. It takes time and energy to chase people to do things properly! I'd advise you allow time and patience to finish it.
