@Pragati Soni to be frank there don't seem to be many issues, a water heater that is old but still functional is not something most sellers will fix, same with the HVAC, now if it is way below on temperature splits, maybe but a degree or two because the inspector has to write something, not a huge deal. 

Again if YOUR paying the bills, you should really investigate further into load reductions... how well the place is insulated. how to reduce water consumption, etcThey Also sell thermostats that can have a remote sensor so you can try to regulate the temperature from a different point then the actual area the thermostats in to try to help balance things.

More popular areas or cities will have a "market temperature" telling you how hot the area is for real estate.

I'm hoping to increase the temperature of the pool by 5-10 degrees in 2-4 days and maintain it.

The home inspector is a Generalist and can analyze things and speak through the lens of a general inspector, but they MUST defer to a specialist on specific issues (for the sake of their liability mainly, and for intellectual honesty, too).A good example is this:  a general inspector can measure the difference in temperature of the air going into the HVAC return vent and coming out of the ducts, which indicates the relative health of the HVAC system. 

Here in California, temperatures have been two degrees hotter than average, making this the 19th warmest start to a summer on record.

If you're going over concrete make sure to check concrete temperature and  moisture content; both affect the bonding process during the life of the floor.

But my agent still has me on his auto-list feeders so I can keep my hand on the market's temperature. 

Plus there arent many cheap options for pressure temperature compensating shower roughs for clawfoot.

@Derrick GrahnToday was the Inspection day part of due diligence.I used Chad Cooper from AZ property inspections, the Inspector came out this morning and we walked the inside of the units inspecting under sinks, closets, A/C for cold air, Bathroom, water heaters, attic space, roof, main on/off outside water valves, washer & dryer rooms.Inspector recommended that I have the sewer lines scoped and because of the age and the property is on a septic system so it must have the system inspected by an ADEQ certified and qualified Inspector.none of the water heaters have on/off valves or Temperature/pressure-relief (TPR) valves which he said they should. he found some mold in two of the units because of 2 water heaters.
