The default tax treatment of a multi-member LLC is a Partnership.

@John T. try this;One idea that I have read about, but never known anyone personally use it is this;Depending on tax brackets for ordinary income (interest) and capital gains, adjust price/rate as needed for best tax treatment.

One of the most important elements in order to qualify for 1031 Exchange treatment is your intent to hold the property for rental, investment or business use purposes. 

Maybe even using one of  the theoretical examples below as I'm a visual learner...

Basically, if you have 2 homes on the neighborhood that get investigated several times of the year for illegal dumping, abandoned vehicles, vacant board orders, or high weeds/grass... it's probably a more distressed area.I also walk the street on Google Earth to ensure that I'm not across the street from a metal recycling facility, railroad tracks, waste water treatment center, landfill, trucking warehouse, etc.Another interesting look is to use Google Maps to find all of the Starbucks in town.

However there is some tangible personal property in the mobile home (e.g. the carpet, window treatments, etc.) that does qualify for 5 year depreciation.

There are rules and regulations regarding the treatment of that, but that is a whole topic unto itself. 

There are some state nuances in a couple of states with regard to state treatment. 

Also, when you look at satellite images, you can see whether or not they have a treatment plant or lagoon...i know you were interested in well vs. septic. 

Bigger Pockets Youtube channel is great to get a visual when learning some of the basics (analyzing deals etc), but also the BP podcats obviously.I also like "cash flow ninja" podcast, and "lifetime cashflow with real estate" by rod klief.
