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.

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.

how sustainable is this model?

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. 

I also modeled out what the investment might look like if the exit cap rate increased compared to the purchase cap rate.2.

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

:Intriguing model – Fits the niche of offering a housing alternative that is cheaper than a studio apartment.

with the subscription model, i pay less for VRBO bookings than Airbnb.
