New build or fix it

Hello all! I inherited a double wide with a very nice amount of land. The double wide was built in 1991 and has a lot of major issues.
It still has a mortgage on it. Around 57k left

I can’t realistically afford a brand new mortgage for a new build but with how many issues the double wide has I’m unsure of my options.

-Needs a new roof, it leaks
-needs new drywall in every room, black mold growth on some support beams
-needs outside siding replaced
-exposed and weak subflooring (I fell through a few spots)
-half of the house doesn’t have electricity
-replacement of a toilet and two baths
-the farther half of the house in sloped down at quite and angel and would need to be either lifted somehow or have one whole side of the house torn down and rebuilt anyways.
-all windows are broken

I’d love to have it rebuilt bit by bit since it’s my childhood home but I’m not sure it’s even saveable with the black mold issues and the sloping. And when I say a slope I mean like. Toes clean curl around it.

It looked like the blocks holding the hole up in that area settled into the dirt more.

Any advice is welcome! I won’t sell because I’ll never be able to own land otherwise lol
