Honestly? I wouldn't find it a big deal. If the location of the property fits perfectly, you'll quickly get used to the "shady side." We also have tall trees to the west – about 60 meters away. In summer, the trees only "bother" from the end of August; then it gets shady around the pool area from 6 pm. However, the "disturbance" really only affects the pool. Our outdoor seating area is on the other side, with a roof over it, so it's shady all day – apart from short sunbathing sessions, that's the favorite spot in summer.
What I mean is: the shade is at most a nuisance in spring. But who has time to lounge in the sun all day anyway? On the other hand, the trees also bring better air, birdsong, peace – no, I wouldn't have any problem with it.
Have you already spent a few minutes there in the afternoon at that time?
[Opposite] three semi-detached houses are being built. Google "Doppelhaushälfte Ziegelhütte" – THEY are poorly oriented! Terrace facing north.... Your property really is a gem!
