Foreigner friendly real estate for buying/building a home

Before I say anything yes I have looked at the internet and consulted a few, but I am wondering if anyone here has any experience buying a house and how smooth were their experiences. Because I much rather not go into this completely blind

My family and I have decided to buy a home here and have me deal with the logistics and stuff since I live here and they will fund it

My family and I have two options which is buying a house (old/new, doesn’t matter) or building one that’s either in Saitama or Kanagawa (depending on options available )

If you guys know any real estate companies that are good in those two areas that would be great

Being able to speak English is a plus since my parents don’t know Japanese and my Japanese ain’t good enough for real estate stuff yet (but if I have to I don’t mind it either, just gotta learn more)

And in case someone asks I’m a resident on work visa and they are not

Ty in advance
