I come from a more institutional level background (most of my career has been selling land to the national homebuilders), so I understand the mentality and how the larger companies like AmericanHomes4Rent, Invitation Homes, et al function.

If the portal had a maintenance request function,  I'd list the instructions for that component as well.

There are several threads about the DST here on BP, but it functions similarly to a Series LLC and is viewed as an estate planning tool, therefore not subject to the tax.

I never have understood maintenance/cap ex as a function of rent.  

Property management can fit here, depending on the function and cost basis, or maybe it's a flat rate and there-in a fixed cost. 5 Reinvestment: The first and most important, often over looked especially by novices CAP-X; this is your known items that wear out over extended time, such as a roof, furnace, water heater, flooring, counter tops, ALL the things.

Created a functional home that was more modern style compared to the 1986 look it had when we purchased it.
