I had it customized to my business with a developer.

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

They think they can hide behind custom contracts and lawyers. 

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.   

Lately I sent out 1,400 advertising cards to 1,400 leads they provide received only 1 yes only one response and that was a legal order of cease.I have several classifieds running with zero results .I have a custom perf sign on the back window of my SUV with zero results to dateAnd a heavily promoted website with very low traffic Did google ads which was a complete flop Would like some feedback about charter financial and the owner Leland RegardsMark

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