The first house that I bought was 17 years old, 3 br, 1.5 bath, brick ranch house with hardwood floors, Andersen windows, ceramic tile baths, gas heat and a brand new roof. 

-Both homes have new windows, kitchens, baths, flooring, electric, solar, landscaping, you name it, with custom tile and woodwork. 

Hardly anyone can prep properly, mask or dropcloth properly, cut in around trim and windows, get even coverage, etc. 

For the last point, it's referring to a window egress.

Typical renovations include:Cosmetic Updates: Painting, flooring, kitchen and bathroom upgrades, and landscaping.Structural Repairs: Fixing any underlying issues such as foundation repairs, plumbing, or electrical updates.Efficiency Improvements: Adding energy-efficient windows, new HVAC systems, and better insulation to increase the property's overall value.The goal of the rehab phase is to increase the property’s market value while making it an attractive place for tenants.

In some areas the window is only open at reassessment and only for a certain number of days.

We had to remove the windows we had already installed in a 1925 house and reframe the openings to bring them to 2023 building code.  

However to save money when she had the house built, she left the basement unfinished--it is just studs, insulation, and windows/doors, plus plumbing in the foundation.

Estimated cost for remaining changes (all new electric, drywall, tile, fixtures, cabinets, roof, doors, windows, heat pump, some siding, and fencing.

The property does have heated radiators through out each unit. everything is separated for each unit electricity, gas, and window units in each property.
