Carpet, LVP flooring, painting, new lighting fixtures and can less recessed lights, new light switches/outlets, GFIs, light plumbing, refinished countertops, and light landscaping.

There were no clothes in the closets, all the kitchen cabinets were empty, there was no shower curtain and no toiletries or toilet paper in the bathroom, and most of the light fixtures didn't work.

There are ways to add structural things like stairs, different door types, appliances, fixtures, and more.Once it's done, it can export as an image, PDF, a 3D floorplan, and more.

If those are the current body colors of the house, I'd go with a rich, warm hue for the entry, like a deep burgundy, and unless it has a decided function, remove the glass "storm" door.Find a couple of matching, cool-looking mailboxes and position them together centered under the window.I'd also paint the garage doors a dark gray, about halfway between the siding and roof colors.Replace the carriage fixtures with something clean-lined and contemporary, and much LARGER.Then, do some landscaping... start with about 3-5 junipers or anything that grows tightly (almost straight upward) in a column-like form, plant them in a row along the front of the walkway, maybe with some seasonal color at ground level. 

For us, it appears that the lower had a lot of updated electrical in the outlets but the switches and fixtures did not get updated at all. 

At 4-5k that should include drywall, full paint, carpet, maybe replacing some items too like light fixtures

Also, they had already made some changes to the shower fixtures in the upper unit (another change they did not ask about).I have a bad feeling about these people, I think they might be trying to take advantage of me.

You could just feel grateful being a millionaire if you see a renter paying 1 room for $2,500 and we pay our mortgage for 2k.Also Chinese food in small tray is stil $2.9 per cup these days :-)Sometimes what's important is what you feel and what makes you happy

If there are empty cans and coffee cups all over the floor, clothes and boxes of stuff strewn on the back seat, and junk everywhere, it shows how the person will not take care of your house either.
