If you think they are dealing you need to make the late night visits uncomfortable by dealing with any specific lease violations regarding quiet hours.   

Is there any specific value - or downside/risks - to deeding the property to the LLC? 

I truly can't give you specific answers that you're looking for.

All in all rates for MF investments range between 7.000% - 8.000% in this specific scenario.

Also if there are any specific zip code or neighborhood in Memphis which are more preffered for short term rental than other zip codes?

I was looking for anything specific or recommended.

But we would like to narrow down to a specific area if possible.

What I often see being a mistake is people ordering a cost segregation study before speaking with their accountant to see if it would benefit them on their return.What a cost segregation study does is analyze a property further to identify assets that be classified with a shorter asset life than 27.5 or 39 years.The issue when getting an 'estimate' from a cost segregation study company is that they are not accountants(more specifically not your accountant).

I like searching for transactions and being able to quickly categorize them, even break down one specific line item to multiple categories.

Hi Rajesh- your question is multilayered and very deal specific.
