Small items may not.  

@Carlisle Edens have you tried or considered trying doing it with a traditional 30 year mortgage? 

@John Pflederer, just a thought and I know this goes against why you have a property manager to do these things, but can you set up a contractor/worker to do some of these smaller, high-expense items like the salt, instead of letting the PM coordinate?

But they probably will require at some point an itemized rehab budget. 

Make sure each part of the job is itemized also try to separate out labor and materials if possible. 

I still need to furnish, etc.For the experts here, do you typically use traditional financing or use other sources?  

Many sellers are uninformed that they are getting FAR LESS than going the traditional listing route.

Traditional financing.

I'm also a bit of a sustainability nut anyway.I'm also doing the other usual items, new laminate and tile flooring, bathroom renovation, kitchen updating and exterior maintenance.

I learned from BiggerPockets which rehab items were worthwhile and the expected costs.
