I co-own a microbrewery and the buildout involved removing everything (including concrete floors) and installing all new floors, plumbing, electrical, hvac, etc.

I never heard from him on Thursday 9/23 and I got side tracked with work I forgot to check in and when I did ask him yesterday Tuesday 9/28 when they will be over at my house to finish up the work he mentioned they already went last week on Wed 9/22, Thursday 9/23 and Friday 9/24 and finished the work, all they needed to do today was to backfill the holes that were dug to fix plumbing and pour new concrete in plumbing trenches.

Helical piles, and leaving me convinced by their expertise and inclined to take action on their bid.I didn't ultimately sign off, as I had not budgeted for that much into foundation work, and have since been able to do most of the foundation slab crack demo & repair myself with some local sub-contractor help.The helical piles approach tho: drive a stake down until it hits bedrock and then neumatically "pump up" the foundation until its back to level...seems like the ultimate right approach & solution I need, before I proceed to a future phase of finishing the attic, bumping out shed dormers, and adding +1000sqft w/ +1bdrm, +1ba, & +1 wetbar/kitchennette for an STR unit.That project phase is a few mos out, and will require a structural engineer, as I'll be adding interior structure posts, a major new ridge beam, and 20' of floor-to-ceiling full-light windows & french doors facing the bay. 

Find an other method where you have CONCRETE evidence that it works and switch to what works.Spoiler alert.

Then, when the tenant destroys your property, you have virtually no recourse.As to the concept of "guaranteed" rent I'm rolling on the floor.

New luxury vinyl plank flooring throughout.

I made an addition in my 1906 house, change floor plan, new electrical and plumbing, finishing still in process, adding value to the house.

There were some interior updates done previously (updated kitchen, flooring, windows), but much better than many in the price range.

The space has an office and warehouse/storage on both floors.

This home has an in-law apartment on the second floor which would be great for someone who's looking to house hack.
