For example, if $100 buys a basket of goods today, in 10 years, with a 5% average inflation rate, you'll need $162 to buy the same items.

So I'm guessing thats the item. 

Your biggest problems here are going to be how to properly qualify someone, what to do if someone stops paying, footing the bill if you have a big repair item, finding quality and reasonable vendors/contractors to fix things, and keeping track of payments.If this isn't you, give me some more context of where you're at and I can give some better insights. 

The biggest advantage of using someone local to where you're buying is that they will understand taxes, insurance, and similar items very well when it comes to DTI/DSCR calculations and payment quotes, and they will likely have a local network of service providers for ancillary services (survey, inspections, etc).

Some items to touch on while you talk to prior investors:How has the overall experience been?

There are various other items that may come up such as: Proper firewall suppression, adequate entrances/exits for fire safety, stair safety, size of kitchen appliances, etc... for my specific example. 

My CPA instructed me to list my repairs as CAPEX or repair items , furnishings were supplies for the rental. 

If Acme Disposal does not accept the items, you must transport them to the landfill.

I also like to use incidental insurance as an additional layer such as Waivo to cover items.

For months, this was what we were following but of course when dealing with me I never make people wait so long and I pay as soon as I am able, as soon as the line item funds drop I usually send a wire or zell payment.
