I talk to a lot of people looking to test the waters. 

This means, site plan has been signed off by the county, building plan is approved, site has water, electricity, and sewer/septic.

Is that because well water is generally harder on the filter mechanics?

Right next to the water meter. 

Do you have heat, water, stove/oven that work, a safe unit?  

Three or more months and have the renters pay for water and electric but offer Internet and yard care. 

What began as a very soft Spring STR shopping season crescendoed with Memorial Day weekend resulting in prime active listings going pending within just a few days and several with multiple offers. 

I also pay for the water so the added income would help offset the bill, thanks in advance!

I’ve dealt with water issues before including using water damage and remediation companies.
