Long lease terms always protect the tenant more than the landlord.Do regular inspections and evaluate come lease renewal.

And while it sounds good at first (total rent, total cash flow) - you can literally buy a duplex that will produce the same rent with just two units.

The good is it was producing roughly a 10% return a year with mailbox money.

Is it just me or do you guys experience these things too on a regular basis?

Otherwise just better tenant screening and regular inspections.

This is something they have the ability to do, but many don't regularly exercise it.

There is a home by me that I am interested in, it's in a great town and I know that it can produce a great profit for investors.

Both always seems to have sales of at least 45 percent off the "regular" cost. 

How many do this regularly?

Also, if being hands-off and not requiring any landlording is what you are looking for, instead of a DST I would suggest looking into regular syndicated investments (i.e., Private Security offerings of partnerships that investment in RE or similar assets).
