Your clients are motivated sellers.You can NOT convert people who do not want to sell  (below market value) into people willing to sell below market value.The mistake people make (constantly) is their efforts are based on forcing non-motivated sellers to sell, by constant harassment.This is wrong.Instead of mass mailing blanket mailing,  and putting your energy in finding random people and forcing them to become motivated by putting a ton of effort and money into follow-up, you need to focus on targeting the RIGHT people.People who are actually looking for your service.Hopefully, it changes your perspective and you can improve your business.

maybe as an MTR...I only own higher-end STRs, our leverage is very little to none.So the real question is how much leverage is there, or another life event forcing them to sell?

There is just too much competition.If you're willing to invest heavily into theming you can force cashflow, but even that is going to be tight unless you really hit it out of the park with your theming. 

STR arbitrage is getting more expensive as everyone is force to add more amenities.
