If your credit is healthy enough you may get financing available up to 85% loan to value on an STR purchase.  

Food for thought: (depending on your big picture and considering all options) purchasing a new, single-family rental property in a healthy metro area where the numbers make sense with a 30-year fixed-rate loan may just be your best bet.

I'm a Real Estate Broker that lives and offices in Gilbert, AZ. 18 years full-time real estate in Arizona, all in the SE Valley (Gilbert, Chandler).Gilbert is a very healthy upper middle-class suburbia community.

Our plan is to only take minimal disbursements from the LLC until its built up a healthy warchest.  

A bit of background info:1) My wife and I after 30 years of working have a healthy stock portfolio.

If you did not, and started later, the likelihood of enjoying that $500K lifestyle in great health is less likely.That same example, deploying immediately into an area with lesser quality (lesser capital required), and you can likely 3X to 20X the end result after a decade, or two, or three.

Netting positive cash flow right off of the bat, after debt service and other costs is solid if you have a healthy financing structure. 

The property prices are more reasonable compared to many other markets, and there seems to be a healthy demand for rental properties.

someone selling an investment should be able to handle a bit of healthy skepticism of their model if they are trying to sell others on the model for their own gain.  

Rentals create cash flow, and that's what we want as real estate investors, but you need cash on hand for unforeseen circumstances.The AC needs to be replaced, that's $7K to $10K or more depending on the size of the house and if you have one rental, it will eat all your cash flow, same to replace a roof, etc, or if tenant trash the home, you need money to fix it again.To me personally a nice rental portfolio that is healthy consists about 10 units, so if you have an issue with a house the portfolio can cover the repairs and still healthy, but when starting you need to have cash on hand just in caseYes, there are multiple strategies you can use to hack your way to buy your first rental with minimum cash, but I would start wholesaling or fix and flip a few deals to create that cash as fast as possible
