It depends on your loan.Your plan is to spend $50k to make $200-300k more a month?

Spending a couple of hundred dollars can reveal major issues.

I have almost 100k saved and am more than willing to spend whatever I need to. 

But it's what my thoughts are and determines how we will operate and spend our money.

There is definitely a stigma about electric heat.So, our current thinking, rather than spend the money on electric heating units, or individual Rinnai's for each unit, is to look at energy savings and heat loss. 

Quote from @Gabe Chase: Quote from @John Underwood: Just curious how much do you spend annually on all the 3rd party software you use? 

One suggested paying a GC a couple hundred for an estimate which sounds good until you realize you might do this 10-15 times before you buy a deal then you are spending thousands on estimates!

Its a small cost but will pretty much guarantee you don't have to spend your time going to a house to unlock a door. https://www.homedepot.com/p/Sc...

The reason is there is usually a resturant or other retail shop there and now you have customers you would never have that WILL spend money while they wait 20 to 30 minutes to charge.

You should only consider switching when your current software has a significant flaw or lacks features that force you to spend excessive time on workarounds.
