OP, hope you don't mind me joining this thread. We have started a similar journey so didn't want to create new one. Have you made any progress?
We have decided to buy a place because we plan to stay in Japan for the remainder of our lives so not really bothered about depreciating asset. Want a place to call our own and live in comfort.
I'm in my early forties already so left it a little late. We are both foreigners and no PR yet (3 years in Japan so far). I know this will make getting a house loan difficult but it's not impossible so we're going to give it a shot. We're both full time permanent employees and work for large stable Japanese companies with a combined income of roughly 10m. We live in Kanagawa, work in Tokyo.
I know for sure I don't want those new prebuilt homes. I've seen a lot of flyers in the mail about those and they all seem badly designed and cheaply made. I dislike living+dining+kitchen all in one room. The kitchens themselves are tiny. The worst thing is that all the homes are squashed together, no pavements, no greenery, no privacy. Just depressing frankly. Would rather rent.
Would love to find land and hire an architect and design my own home from scratch but we really don't have the knowledge or time to do it.
So that leaves a used house or stock/custom house from a builder. 10-20 year old used home would be perfect but need some luck to find one in a good location. There just aren't that many available are there? Something bad must have happended for the seller to sell at a huge loss...
We went to a model home park (in Toyosu) for the first time last weekend to have a look at new houses built by the big names. They were amazing! Obviously those are unrealistic for us and are there to show off their fancier designs but interesting anyway. We were going to visit all of them but only managed two. Takes a lot longer than I thought and is quite mentally tiring speaking with the sales people (our Japanese level is not great N3/4 level).
Our mistake was that the two we visited may have been the most expensive companies, Hebel and Ichijo!
The model homes were very large but what surprised us was that they were both three stories. Apparently meant for multiple generations of families in the same house. Hebel quoted 90m and Ichijo (iSmart model) quoted 80m for the house alone!
Although, we are only interested in a single family house with two stories but would like some decent space.
Apparently Ichijo have underfloor heating in all their houses which is uncommon in Japan I think. Hebel have a 30 year warranty which sounds great and the sales guy was pitching the fact that their houses last a lot longer than others (70 years+). Both seem really well made with good insulation. Hebel house seemed a little bit more premium in my opinion.
Anyway, going to try and visit some other companies in the next few weeks that hopefully fit our budget better which is around 60m max. including land. Maybe our budget is unrealistic.
Sorry for the long post
My question is, do these companies divulge the rough construction costs of their houses anywhere? So we can rule out those that are out of our range. Obviously it would be an estimate but it would be nice if they gave example like "this model, this size and design, without appliances costs this much to build".
