I would have VF guarantee that VF takes over all rights and obligations including easements, i.e., you build the cable at your own expense and VF then takes over the line, thus also being responsible for maintenance from then on. There are also so-called protection strips around the cable that must be kept free from construction so that access is possible in the event of damage.
Development carriers do not do it any differently: a road is built with all supply lines, etc. and when everything is finished, the city symbolically purchases it for 1€ and subsequently assumes the traffic safety obligation.
Of course, the question is whether it is worth it for 2 houses. However, if more neighbors join in, it can only be done that way – otherwise, you yourself are responsible for maintaining the line and then you have to build reserves for it, i.e., generate income, i.e., collect monthly fees, etc., because basically you are then a franchise of VF.
