In my mind, if the deal were all cash, and investors only signed up if they knew what they were getting into, its quite hard for anything bad to happen, other than a significant underestimation of costs (completely preventable with duedil before appearing on the platform), or supply outgrows demand (which is a long way off for Ireland).

Can each property rent be paid to and individual property LLC bank account on the platform?

You must incorporate a system into your operations so that you can have a platform for your VAs to work from.

Do you use a standard mls lease agreement or are their special terms you adjust to make it legit?

1) depends on the actual language in your state realtor contracts2) the agent would have to be asleep at the wheel to let his seller accept a contract without a legit POF/preapproval. 

First, you shouldn't give money to a contractor without some evidence that he's legit.

I'm sure this is 100% legit!

If that property is in a nice location and the rent rate is legit I'm surprised it hasn't sold yet.

My broker and I started a property management company and are using the Buildium platform for all of our properties.

I've read a little bit on the website about the platform, but I'm guessing I''ll get better feedback on here.
