What is the reason behind wanting to build new versus purchase existing?

Cash flow very rarely exists in this market, so don't try to fit a square peg in a round hole.

@Bob StevensI was making an assumption that rent was not up to FMR For example in my county if you forget to ask for your yearly raises the dispersion becomes massive and eventually FMR changes can be drastic YoY for a new packet versus keeping an existing relationship.   

The only one I'm aware of is an existing property that they bought.

There are already many existing assisted living houses in my neighborhood, and I am thinking of doing the same, but only leasing my house.

Existing property full stabilized being sold off by the developer or 2nd or 3rd generation owner.5.

First I showed them my existing rentals, then I showed them properties listed for sale in the multi-list. 

Low inventory, but they exist.

I would definitely get a loan on your existing home before you buy your next one.

Bond yields are non-existent.
