I've gone thru CL and captured several rental listings that seem to be owner/self-managed.

They all capture your contact information and sell it at exorbitant prices to several agents simultaneously, which is why you're getting so many calls.This is the business model of the 2000s. 

Not to say a lender would not, but more likely would be if a violation were to exist, the lender may demand you to refinance with another lender but to call the note due, in my opinion, would be remote.The rent capture requirement does seem restrictive. 

For many technical reason, these digital sensors all work better at capturing light at daylight temperatures than at the more common warmer indoor lighting temperatures.

Capturing a 10%/yr appreciation + 5%/yr COC is simply awesome since you bought this duplex!!!  

You are giving up a ton in equity capture with your 100% SF scenario is my main observation. 

I have signed up for Buyers on Fire (back-office management program with sweet spot locator, lead capture numbers, pipeline management, and comps calculator.)

I'm recently US.Army retired and a chef. 

I just migrated to Rentec Direct as I pretty much had enough of “free”.... 5 business days for payment, no real management features (such as COMPLETE capture of info from prospects to tenants to auto lease generation (using DocuSign’s engine).

Your landing page has to capture the attention and create the desire to cough up a name and email address (or whatever info you're collecting).
