I personally do not use their maintenance features much bc they’re pretty clunky and honestly don’t make much sense unless you manage an in-house maintenance team.

Without proper support, removing the wall could have compromised the structure of the entire house.

Many successful investors started small, such as with house hacking or buying affordable properties to rent out.

If it does go to probate, hopefully your brothers and you can amicably go the informal route vs formal (I've worked with families in both when buying properties out of probate and informal is FAR easier).Since there's no debt on the house, maybe you could sell with financing or maybe you could even buy out your brothers with financing -- that way you maintain ownership and just pay them a monthly amount.

This is more of a reach goal for me since I am still in my "collect 4 green houses before trading up to a red hotel" stage, but I thought I would ask the hive mind anyways.

If she went to buy a house and applied for a mortgage, I think the lender would say the same thing aka you don't qualify until you get this removed from the credit report.

However- as the land around them develops, the house will become worth less on the retail side, but at some point, a developer will come in and pay way more than the retail value in order to include their parcel in a larger development.

No loan, I paid cash for the 5 acres and built a pole house myself. 

Mike Lambert above is correct about house values in Japan.
