I mean technically you own the house and the bank owns your loan (with house as collateral), but I do get your point about taxes. However, if the bank had to pay the taxes, they’d just wind up incorporated into the loan. And if the bank actually owned the home, you’d need their approval for any changes.
As for mortgage insurance, you can avoid that with a large enough down payment (20%).
As for the full cost of the loan, I thought that is part of the standard paperwork? If not, sounds like you might have had a bad realtor. You can also look up that info online with any mortgage calculator.
The server for this product is Microsofts cloud, so there is no server cost, you’re just bought into their ecosystem and maybe a slightly higher subscription cost.
It also means little to no hardware maintenance and streamlined IT processes.
I’m bot saying it’s my kind of approach, but there are definitely a lot of companies that could benefit (given most people are really just using a browser and maybe some word/PowerPoint software).
