A new HVAC system properly installed & maintained should last around 15 years.

Seemed very thorough and  had a very easy to understand color system in the report to let you know how bad the situation was.

I can't quite see where I'm going, and advice from those of you who have navigated these waters already would be very much appreciated. 

"Let's look at your water heaters"...."

I've noticed a lot of Tri-plex (3 family) houses have one central heating system I've looked at lately.  

Bad tenants always take offence, even though they know my system beforehand, and will dig in.

This system has enabled me and my associate investors to make lots of fast money.

I've been looking at eCampaignPro as a marketing resource.It's a national email list of roughly 800,000 real estate professionals.They say they have been trusted by real estate professionals for 15 years, and apparently they build their list from opt-ins that that you can click on when signing up with major MLS systems, etc.Do any of you get their emails?

Millard and Papillion also have great school systems.
