as an experianced builder and property developer i understand the full implications of renovation and new build , the costs for renovation in france is a lot more, the main reason for this is not cotisations or tax but overcharging so called builders some of the work and prices here are mad the main reason for this was the lack of good tradesman and rubbish ones taking advantage of the situation , i as a builder can make any renovation pay , the man secret is not selling or renovation costs they are fixed to a degree but buying at the right time , and now is one of those , there are some great bargins to be had but dont feel sorry for anyone or there sob storeys looking at places , if you do buy a place in the charente /cognac area i can recomend a good building team who dont overcharge and another thing property in very cheap in central france for a reason , limited buying market ,
