Lodging US Tax returns

Hi guys,

just wanted to get people's opinions on lodging tax returns for your U.S investment properties and how everyone goes about it. I have posted some questions below –

Assuming a relatively simple one property LLC is this the sort of thing someone could do themselves?

If using help from within the US how much would someone reasonably expect to pay for returns to be done for them?

By my understanding for my situation i'll be looking at 2 x individual returns for a 2 member LLC + 1 x LLC return which will eat into any return i am generating if the cost is to high- is anyone in this same situation?

I assume the cost would be deductible as it is here in Oz

And on a seperate topic if i was considering shifting back to having just the one member of our LLC rather than two to cut costs is that easy to do and anyone done this before?

Thanks guys
