THe best I have seen is up to 89.99% LTV on a second meaning you'd still need to come in with 30K+ closing costs. 

Are you saying you will actually need to possess the 20% difference in cash to bring to the first mortgage closing?

Also check with @Joseph Chiofalo for some further STR investor loan programs and he has a close tax rep we work with.

Looking around Jacksonville, Orlando (of course Disney is the attraction point), Fort Lauderdale or anywhere close to Atlantic. 

and I know there is some form of cancellation but not this close to the stay and If I could i would postpone 2 days so the first day of fishing is not in snow flurries :)the other major issue for me is POINTS  i earn enough points each year to get 10 to 14 free nights .. like in Puket  or last fall in Lisbon or a few years ago the Hilton Wikaloa on the big island and they upgraded us to a suit that was easily a 7 to 8k perk all for free.  

It's supposed to ensure there are no surprises after closing.

I don't think listing with an agent will work since I am not looking to sell to the general public, I do get these yellow post cards and letters from "CASH FOR YOUR HOUSE NOW" but I believe those are not investors buyers but more bird-dogs looking to get it on a contract to reassign at closing. 

We expect a still-sizable gap between 2024 housing inventory and the pre-pandemic housing market to persist as it closes only gradually.

What's the best way to beat an all cash offer as is with no contingencies and a quick closing?  

Ideally, I'd like to be all-in, including purchase and rehab, for approximately $115K-$130k while adhering to the 75% rule (or close to it) in a C-class or above neighborhood.
