There are dues you pay to get wiser, some are more painful than others. 

The tenant has been a pain to deal with on other issues and I'm pretty sure he does not want the inspection to happen as he knows he will be responsible for the repair.

That allows me to "talk shop" with my investors so I can be able to empathize with them on any of their pain points.

I have a local ac guy i've used for 10+ years if you want another local quote, @Elton TidwellPersonally if you plan to keep it long term and every want to raise the rent, central heat and ac would attract better quality renters imho... window units scream 'bottom shelf' and are a signal of what renters can expect in terms of quality and rent... 

Be a slight pain in the rear, without being too big of a pain.

Another had hidden foundation issues, that were obvious from the inside, just not from the outside.You will sign all sorts of lies on the paperwork--you inspected the property, etc. 

Can you imagine the heartbreak and pain thousands of people, that are facing tonight and the next following months, most likely will carry on in them for the next few decades from now!

@Tiffany Milan I'm starting (actually starting again) and like @Jessica G. said, there's a point when the yuck of NOT being in on the RE momentum is more painful than the yuck of any RE excuses I may have.

Stick with defaults.HVAC systems are a pain in the ***.

It always works better for me to ask questions and find out more about motivations and pain points than to try and just assume that I know how to solve their problems.
