Re: Use savings or borrow to built house
Maybe use some of your savings.... given the nature of your job, you should be hanging on to some rainy-day money, despite the cost of doing so in the form of a slightly larger mortgage.
Actually, just re-reading the thread, if you have the €45k for the site, and are guaranteed a contract for the next few months to allow you to build up a rainy-day fund again quickly enough, go ahead and buy the site without taking out a mortgage. Out of the €20-30k you estimate you can save over the next 18 months, I'd keep some of that aside as a safety net.
