A huge number of properties we have looked at would have issues on this front.It can lead to an opportunity to improve the value of a property if you can buy it with an illegal area, get that area legalised and then sell on with a higher value that the bank would lend against, but it's not clear cut and it seems though that there are almost two levels of 'legalisation' - we were able to register all of the annex on the plans and could fully incorporate a portion of it but there is another portion that is too close to the back boundary wall that should only be used for things like storage and not ever for habitation. 2) During the purchase process be careful, amongst other issues with this property we had the situation where the seller's lawyer was not actually a lawyer (having been struck off).

These are big money plays life changing profits but RISK you bet..

Betting on future price appreciation and equity growth is just that "betting". 

I bet the rate of Engineers going homeless is all but 0. 

The quicker you can take action on the high dollar value decsions the quicker you will be able to grow.For sure take the time to setup the right foundation, but keeping it simple and easy when you are getting going is a safe bet!
