I needed to clarify @Mindy Jensen, let me try it again; would the cost to skim coat and texture a circular pattern like this, cost the same as removing a popcorn ceiling, about $3,000 to $4,000 depending on size of house? 

Correct it's a circular calculation- so the gain will go into your overall income determining bracket and the rate applies proportionately 

Changing access to the basement to a circular stair or something that takes less room would enable me to join kitchen with dining and make it more liveable for us but more valuable for resale as well.

Did you cut the cabinets with a circular saw?

- Vinyl Plank flooring (instead of carpet which would need to be replaced or cleaned, making vacacany longer)- Curtain rods (instead of blinds that will probably get wrecked, tenants can supply their own curtains)- LED lights (so that we reduce mainteniance costs, since LEDs generally last 10+ years)- Simple Yard / Grass (for quick mowing)- New / Newish Appliances (to replace the aging 26 year old ones that came with the house)- Simple paint scheme for touching up paint (Grey walls and White trim is working great so far)- Door knob stoppers (The circular ones the doorknobs hit so they don't hit the wall, or baseboard ones)- Getting high quality contractors for major home systems (HVAC, water heater, etc) for a high quality install- Forget the waterline to fridge or icemakers- Plastic piece (similar to plywood) on kitchen and bathroom sink cabinet floor to keep from from rotting from leaksWhat ideas can you add to my list?

Take a circular saw and set it where the blade will only cut about 1/8 inch deep, just enough to make it through the thickness of the board.

Otherwise, drop them in the circular file under your desk.

You seem to be making the circular argument that since Zillow is not a licensed appraiser that it shouldn't have to have a license for its activities.

We could have let them pour over this, but then we would have to pay about $100 per hole to have a concrete "core" driller come out to use a circular saw to cut a hole.

These days the Greensheet provides both a hardcopy newspaper style circular and an online ad.
