As a guest, I can imagine being frustrated if I could not get a home to a temperature that felt comfortable to me.

Heat was off and Chicago area had sub zero temperatures and it just started thawing that week. 

@Michael Rinde   I  would ask them to keep the thermostat at a certain temperature. 

Outside of installing tamperproof thermostats that allow a range of temperatures that you set, not much you can do in the middle of a lease. 

Guest behavior often tells a different story.Comfort Directly Impacts ReviewsComfort influences:- Sleep quality- Daily usability- Stress levelsThese elements appear repeatedly in positive reviews and repeat bookings.Research from the broader hospitality industry consistently shows that negative guest feedback is most often tied to comfort failures: poor sleep, cleanliness issues, excessive noise, or temperature problems rather than the absence of luxury amenities.

Quote from @Marc Winter: After just finishing my home inspection recertification, I plugged your question into the system, heres what it said:Most likely cause: Differential movement + thermal expansionThis type of crack is commonly caused by one or more of:Thermal expansion/contraction of a long brick wall (brick expands more than people realize)Lack of control joints in the masonryMinor differential settlement between structural elements (floor line, lintel, or bond beam)Possible interaction with a floor diaphragm or window header lineHow I’d classify itCategory: Non-structural / serviceability crackSeverity: Low to moderateRisk: Usually cosmetic unless it continues to growWhat would confirm thisCrack aligns near a floor levelNo stepped “stair-step” patternNo widening at one endInterior walls at same level may show hairline cracksThe stepped / jagged, diagonal through mortar jointsWhat it looks likeStair-step pattern following mortar jointsChanges direction vertically and horizontallyLocalized area rather than full-lengthSome patched/effloresced areas nearby⚠️ Most likely cause: Foundation movement (settlement or heave)This pattern is classic for:Differential foundation settlementSoil shrink/swell (expansive clay, poor drainage)Localized footing movement (corner or bearing point)The stair-step pattern forms because masonry is weakest at mortar joints, so stress releases there.How I’d classify itCategory: Structural movement crackSeverity: Moderate (possibly increasing)Risk: Needs monitoring; may require repair beyond cosmeticWhat would raise concernCrack width > ~⅛ inchNoticeable brick displacement (one side proud)Interior drywall cracks aligning with this locationDoors/windows near this area sticking🧠 Why these two cracks have different causes (important)Even though they’re on the same wall:1. global wall movement (temperature / restraint)2.  

For housing and MBS, the near‑term setup is constructive but measured: spreads remain wider than historical norms, implying room to tighten that could pull retail rates toward the 6% zone if basis compresses, while mortgages apps have shown incremental life into year‑end, up 4.8% at last temperature check.

Hi Phillip,I'm also looking for an answer to this question, both for rentals and as an inexpensive aesthetic upgrade to your primary residence.I don't understand the objection that epoxy floors will be "cold" people who like hard floors aren't worried about the temperature of them, they walk around in socks and slippers, no one lays on the floor.

Another had automated welding which is commonplace now.  

Temperature and humidity.
