I guess that's in the domain of commercial lending. 

We use Mandrill but it's for forgot password, invoices, receipts, task reminders, notifications, etc...We weren't able to find a solution for this either, so we had to develop our own software and integrated our gmail account for sending day to day emails but we are using Google Apps for business, so emails are coming from our own domain name.  

Regardless anything less than 2M +/- is left to be the domain of local banks and credit unions.  

I think this falls into the accessory dwelling unit( ADU) and Tiny House domain.  

My properties are privately managed, not by myself, so they don't take away from what I currently do.(mainly

If you dont want to build your site , you can buy the domain name then go to a site called fiverr com and pay someone very cheaply to build you a site. 

I've chosen one specific domain to play within (MF apts) and 2 main markets, but can't seem to bridge the gaps to close a sale.

It looks like a real great domain name and maybe he generates many leads, but I don't see how someone can pay $200-300 per lead without knowing any information about your lead generator. 

Is it better to have a website domain that is the name of our business, or something more "searchable" such as something like www.ibuymycityhouses.com? 

My property was condemned (eminent domain) by LADWP.
