I am also looking for information regarding fee structures, and what item's that should be and should not be included in the management fee calculation. 

Have you modeled out a vacancy period post sale-leaseback term?

A STR is both a business and a real estate investment.Having little oversight on a newly formed business would make me anxious also.As others have suggested, you should consider going to the area for the initial items(Purchase, renovation, etc).Once you buy 1-2 properties, you can look to unload these items to someone else.Best of luck

I've even heard of GCs using auction type settings for returned items at Home Depot and Lowes for steep discounts.I've learned a lot about the GC game as I was up close to over 40 projects last two years and some went well and some did not and when they did not it was all Contractor related.If a GC isn't sourcing cheap materials at the same time milking the hell out of his 150-200 per day workers, then you can find yourself eating into your margins real fast. 

I've been trying to find some folks that would be open to developing it into what amounts to a 0% down investment property financing model.

Water heater 12 years to replacement (may need some service before replacement).Recognize many cap ex items are years away.  

We have had a couple evictions and I agree that the model is not the best for property owners.

The resources are abundant - spreadsheets, contracts, tangible items to help you succeed.

Sorry not an expert in the padsplit model but did you analyze what it would bring in as a whole home rental? 

We can't do the inspection until all 3 of those items get installed.
