you are so right martin.
The law is now very heavily weighted to the tenants side.
Paul - this can usually go quite well, but in some cases can be downright horrible.
I've seen LL's eventually lose the home they were renting out, purely down to finances, but that is at the extreme end of the scale.
Worst I reckon is you'd have to redecorate/replace floor coverings etc.
Do ensure you have a GSC for the property (LL's can & have been sued over not having a current one)
From next year, you must also have a full electrical check & cert (not sure of date - airbrushed from my mind atm)
Finally - read here for advice to TT's:
