Do we need another group and if so, how will it differentiate itself from the existing ones?

I know every city is different. I

Zillow doesn't have a headline in its listings, so edit your lead photo to have "30+ day rental" somewhere so people on Zillow can differentiate it from a traditional LTR. -- You can post on Furnished Finders, but we've found with our rentals and with those of our clients in Colorado that they're not providing nearly as many solid leads as they used to.In terms of lead-time, it depends.

You must find a way to differentiate yourself.Many of the selling strategies that were effective just a decade ago no longer work today.

@Andrew Johnson makes a good point in differentiating between between a capex and defect issue when asking for concessions - the owner may actually go for that or at least see a "valid" point of view from your side. 

I'd like to be able to replicate some successful techniques with an understanding that some variables will of course be different. I

Even there, there's a differentiation of areas where there are somewhat nicer parts of Linden (C neighborhoods) and then a great deal that's a warzone (D Neighborhoods). 

It combines features of a HELOC where it factors money daily (how you save your interest), it takes the max ceilings and floors for rates like a ARM mortgage, and it also acts as a checking/savings account in that you can store and draw money from it for the life of the term (usually 30 years) unlike a HELOC where its 10 year draw and 20 year Principal and interest no more draw after year 10.Where the benefit comes in is opportunity cost of interest since interest is factored daily you could park your pay checks, savings, and other cash instruments into this LOC or HOA loan and save on the all differential in daily interest charges that would normally be paid with a standard 30 year fixed mortgage or other typical mortgage that factors interest/amortization "monthly."

The networking connections are the major differentiator I think.

High end luxury homes may be different.  I
