Given my tech and data background, I'm considering developing an online app specifically for Canadian investors.I'm envisioning an interactive dashboard that integrates economic data, sales figures, bylaws, and rental information, complete with prediction models.

@William SilvaSTR and LTR are very different models.  

I understand the business model, but I would like to see the thought process of someone actively running a Short term rental.

I just made an excel model and you're right! 

I have seen two different pricing models - one by number of BRs, second by sq.ft.

I made 12 videos to launch Express Offers when it started at eXp and they had good intentions, but you have to understand that all of these programs and outside programs are based on the same model.

how sustainable is this model?

I know there are individuals working on data analytics for this as I've been contacted by a few who have early models they're wanting to test.

Some of our initial baseline, no-go, criteria when we first listed were: 600+ credit score, no evictions, no bankruptcy, and income 3x rent... however, after finding that very few interested parties were eligible to even "enter a review phase" of landlord verifications etc, we loosened up a bit and went to an objective scoring model that I tweaked from a few ideas obtained after speaking to both rental professionals in my local area and some on this forum. 

Depending on what model I use, I obviously get a different DSCR.
