Getting Under Contract on STRs in Today's Market

Been putting in a decent amount of offers on STRs in PCB, Gulf Shores, Blue Ridge, and the Smokies but am continuously getting beat out by all cash offers on $400k+... Anyone else experiencing this? I unfortunately can not ball like these folks this early in my REI career so I am trying to think of ways to get creative. I feel like I have tried getting as creative as I can with agents in their respective markets short of waiving inspection contingencies and the full appraisal contingency. Curious what other people are finding successful in similar markets? Also curious if there are lenders who will front all cash to buy a property for their client and then finance the property to the client before closing, similar to wholesaling process I suppose without it being wholesaling? Any help or suggestions are greatly welcomed, thank you!
