As a possible solution, I located an online form submission site that allows me to create a custom form, to which I can provide a link in my advertisement.

You can check out rental sites to see what is being advertised, but I definitely wouldn't rely solely on Zillow's guestimate.  

I will be doing some 'word of mouth' advertising with peers that are either in the market for a new home or have friends about to purchase a new home (most of my friends want turn key properties).  

Renovation time depends on what's needed and you can start advertising for tenants while renos are underway.

I am moved in, but will be doing some work to the rental unit before I will advertise it for tenants.  

Otherwise, you may not legally be able to advertise for sale that which you do not own.

If you don't advertise it publicly but offer in private, you don't promise anything.If you do offer the premises for rent publicly, it has to be compliant with Fair Housing law.It's a slow time in rental business and if you never find who are you looking for, are you willing to take on financial losses because of that?

Part of my dismay with the method is that I see A LOT of people advertising that they offer this service.

and led to substantial job loss, likely the number one cause of foreclosure.2) The tourism and convention business, a huge portion of New Orleans economy, effectively disappeared for a couple of years - again huge job losses.  

I hope to continue to get last minute bookingsIt has made started starting to advertise on other platforms.
