I started doing a regular routine of enzyme treatments every few months I use either Ridex or the enzyme sticks by Green Gobbler down each sink and shower every month or so and no problems since. 

In 2011, the company who did the treatment had to return 4 times to totally get rid of them, but in 2017, only 1 treatment was enough. 

I agree with you that seeing the industrial window is always best and yes window treatments can get really expensive.

About the only way you can do it is build in the county (not in a city), and when you do this you may be able to connect to municipal water but you will almost certainly have put in your own septic systems or sewer treatment, which gets expensive.  

There are people renting STR because a family member is in the hospital for weeks of treatment and they like to be close.

Typical radio silence treatment that has become all too common with the times.  

It’s is sometime better to start earlier just to document for the long term cap gain treatment. 

You may have your own sewage treatment plant .you will need to buy a large tractor with loader, a small dump truck , lawn equipment , golf carts for employees to get around .Build a house or 2 for management to live in . 

When we took it over we discovered the entire building was infested with bedbugs so badly that our bed bug remediation said if this had happened before heat treatment was introduced the building would have probably been torn down.

@Rafael Trinidad Buy, build, Then hold for over 12 months could get you long term cap gains treatment.
