Asbestos becomes porous with age and the individual flying fibers are already carcinogenic, not only when cutting or demolishing.
For surveying, there is a specific price catalog that all publicly appointed surveyors must adhere to, therefore the prices are generally always relatively similar; you can of course compare, but you will not be able to detect large price differences. Ultimately, you cannot prepare much, except if you can clear all the old and new property corners, which makes the surveyor’s work on site much easier and saves time.
Please also note that you need a notary for a property purchase and everything must be registered in the land register, and you must subsequently pay the real estate transfer tax. Notary; registration and real estate transfer tax are always approximately 5% of the purchase price, but if you receive the property as a gift, usually a market value is determined.
