@Jewell ArceneauxFrom my experience, focusing on impactful upgrades like kitchens, bathrooms, flooring, and curb appeal yields the best results.

There are various other items that may come up such as: Proper firewall suppression, adequate entrances/exits for fire safety, stair safety, size of kitchen appliances, etc... for my specific example. 

Sorry to rebuff your favorite influencer with an office at their parents' kitchen.14-day free rent aka Augusta rule loophole.

There SOW would usually be - 'I want a remodel done on the kitchen and bath, and add a new bedroom on the left side of the house'...Then I would add items that only a GC would know about or notice, like needing new headers for the openings they want, the elec panel being undersized, or the roof being suspect, etc...Together we would then arrive at a comprehensive SOW.Yes, that is much better scenario.

I came across a 2-flat with a basement that has been converted into garden unit with 3 bedrooms and kitchen and bath.

Aside from not paying any rent since July, claiming she lost her 2 jobs due to COVID19 (and the California eviction ban protecting her) she's been complaining that there's a gap in the kitchen floor where flies could fly in, and black mold in the shower.  

My longest recent rehab was 2.25 months and added a half bathroom, took down 4 walks including load bearing, put up 3 walls, new plumbing, electrical, flooring, huge percentage of drywall, an eye brow porch, new kitchen with full layout change and new bathroom with full layout change.  

If you finish the basement with a kitchen you could have a mother in law with a walk out and a garage downstairs.

Kitchen arriving in 21 days.

Also converted what was once a restaurant/kitchen to a coworking lounge with views of the ocean and pool/patio area.Redid kitchens, painted, added swing, hammocks and created social areas.
