It'll be a bit riskier than buying something already renovated, but if you have the right team and numbers in place you could pick up some more equity on day 1, have less money out of pocket, and have something that produces some cash flow. 

There could be better options where you can still keep your monthly a bit lower with a higher income producing separate unit.Hope this helps!

You'll need to produce evidence that the unit was left in a condition that didn't require cleaning.

I'm only building rental cabins which is a higher price point due to their ability to produce income. 

Vacation rentals in these mass-produced STR "neighborhoods" are really just a commodity, similar to a hotel room.

As far as a reasonable fee, I'd say it has to do with the value brought, and product level produced.

If you set them up as a "property manager" who was required to produce X amount of income to you (i.e. your rent amount) and then they'd get the rest. 

Once you pick one give it a serious dedicated effort, but if it's producing no fruit after several months you can always pivot and shift. 

In 10 years it is virtual certainty that a leveraged purchase today would have produced a good return.

That doesn't mean it isn't a good strategy - if the property still produces healthy cash flow after expenses (which includes future capital needs if you've deferred such), at a minimum you could be rolling the cash flow either back into the home to own it outright or using those funds to prepare for your next purchase.
