Water to the site was a challenge that has been overcome.

We have one down in Colorado Springs but they are many in Denver too. 

Problem here the tenant didn’t declare cats as pets.She ruined the unit in one full year and it took more than $11,000 to replace full floors in two level townhouse plus other water leaks damage.tenant left without telling.Now I am asking property management must visit quarterly to catch damages early on.Ozone machines did not help much.thanks

But there is nothing like the eyes of someone that has installed a water heater, replaced a breaker box or laid a floor to really get to the bottom of the true issue on a home fast. 

Here in TX the soil is mostly clay, and it shrinks and expands with humidity level (thus the need to "water the foundations" as a measure to avoid foundation cracking), so foundation problems are a common occurrence.

Curious if anyone has tried the smaller 20 gallon water heaters? 

and two of others (furnaces, water heaters, appliances, etc.?) 

Electric stove, dryers, water heaters, and high-efficiency Mitsubishi heat pumps.

I am interested in a home that is located within Houston-Katy-Cypress-Spring-Missouri City-Richmond area to turn into a residential assisted living.

It has separate gas, electric, two hot water heaters, etc.
