I could likely see many things from the TCJA being made permanent, mostly procedural items like the higher standard deduction and child tax credit (Plus eliminating exemptions).

Depending how long your LTR was in there, you might need to fix or update a few items. 

If the property is making money - and I mean really generating good cash flow - then those taxes are just another line item in your budget.

Now, I typically only use them to skim stats on reviews and the more basic items. 

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

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.

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).

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. 

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.
