I am looking into ways to find statistics on how many visitors the town/area get per month or year.

They are better purchased from a financial advisor that is regulated by the securities industry who educates their client not only on the risks of a DST but also ensures it is a suitable investment in terms of distributions, investment goals and tax strategy.

Does it mean LLC is more flexible/suitable?

Maybe not entirely suitable for large-scale setups, though.

About 6 to 10% (your "conversion rate") will complete and submit the form.So if your average cost per click is $10 and 10% of the visitors complete and submit the form, your cost per lead will be $100.In most markets, the cost per lead avg is probably closer to $150 from AdWords.So, if it takes 20 leads to get one "cash purchase" deal under contract, your marketing cost per deal will be $3000 (or 20 x $150).  

These are high end products and not really suitable for rentals - - why? 

Or maybe the landlord would agree to begin re-marketing the unit with your brother paying rent until a suitable replacement tenant can be found.At the end of the day, your brother is bound by the terms of the lease that he signed, and trying to slip something past the landlord/property management company is not likely to end well.

If the gun was legally owned, there isn't a problem with the law there, its not the same as drugs.If its your tenants gun and the visitor shot it, then there's a big issue of securing that firearm. 

A visitor will give you 5 seconds to decide if he wants to remain on your site.  

The duplex is located in an A class neighborhood, right in the middle of a nice residential neighborhood, so it would not be suitable for a hungry investor looking for a run down beater.
