Exterior doors sizes (12x12; 12x14; 14x14) and mechanisms (chain, remote)? 

With that being said we can’t close any walls and decided to work on the exterior but that’s even a struggle the GC will tell us “we’ll start on that tomorrow” but tomorrow shows up 3 days later.

@Stephanie Ro I actually went for a condo because of the best money for the bed/bath combo that is the largest factor in price renting to students, and also exterior maintenance and landscaping and being able to offer a pool/volley ball court/basketball court that checks the boxes for the kids. :)

I also check exterior hose bibs for leaks. 

-opened up the floor plan by removing a few non-load bearing walls-painted entire home-new can lights-new appliances for renters downstairs-scraped popcorn ceilings-new LVP flooring up and down stairs-new base and door casing-few exterior adjustments like small decks and cleaning up yard-added accents like shiplap wall and white-washed brick fireplaceThe basement rents at $850 /month and we rent a room upstairs to a friend for $300 /month.

In comparison to wood frame exterior walls have a dead load of 10psf. 

Replace any window, glass, exterior door.

Modern plumbing and electrical, brick exterior, water drains away from house, no large trees near house, etc- No one will look after your property as well as you want them to.

I was a property that needed some work had older 50's wood paneling some of which was missing and you could see that there was no insulation in the exterior walls.

Exterior - plywood, sheathing, siding, brick, concrete blocksAnd then as @Michael Volek mentioned, you have to understand how these things are done within the code depending on your state, county, or municipality.
