I think the convivence factor for the customer isn't there. 

I had it customized to my business with a developer.

We're currently shifting gears to custom and semi-custom homes. 

If you are looking for unbiased feedback on PMs we get a lot from our customers and would be happy to pass it along if we have intel in your area. 

LICENSE AND FEES $8000, CUSTOMIZATION OF THE HOME $5,0000, CONTRACTORS (I HAVE NOT IDEA JUST FROM WHAT I HAVE BEEN TOLD $5-$10,000 BECAUSE THERE ARE NO HEAVY LIFTING, CRANES OR HEAVY TOOLS), AND LETS DO $10,000 FOR EMERGENCIES.

Ideally you want to make sure it's near a major highway so tenants have easy access points to their customer base, especially with the trade type tenants like plumbers, HVAC etc.   

I do know that the more complex/custom you make it, the harder it is to maintain.   

Also, accounting/ metrics are a BIG DEAL because we have a property management company so we need more features to customize reports and look at accurate revenue data.

Previously, I dedicated many years to selling custom and semi-custom residential properties for a highly respected and well-known builder in Atlanta.

We get a lot of intel and feedback from our customers across the US.
