Do you know the age of the water heater, HVAC, or roof?

Anything from leaky roofs/windows, flooded basements/crawls, and failing drain fields/septic's.

We are doing roof, windows, full electric, all plumbing above the slab, new water heater, installing new central a/c(it had window units), 70% new sheetrock, cabinets, vanities, flooring, insulation, and some framing for rotten wood under the windows, and changing out all doors.

If no back up and just a smell, pouring a gallon or two of water down each floor drain in the basement can often help with that. 

I’m keeping it now because alreAdy water under bridge and policy is finally close to breaking even.

In pre-retirement, we'll live there part time so proximity to large body of water is preferred.

I will cover utilities up to a budgeted amount of ~$1500-$2000 a month as well as water and wifi.

Hopefully is near the water. 

I would suggest winterizing, drain the water lines, antifreeze in toilets, leave lowest faucet open etc, incase the heat shuts off 

But also added on an unpermitted thankless water heater, built-in microwave oven and added can lights in each unit, and changed 12 windows to double pane.
