A few thoughts:With retail it is in most cases nnn where the tenant pays the expenses.With residential you get more turnover but a better chance to raise the rent.With retail you have longer deals usually 5 or 10 years but less frequency to raise rents.

But I think that also depends on the frequency you're doing them and how much money you have to play with.

A war zone is defined by the frequency of violent crime, not by the condition of the properties.

I'd also love advice on marketing the unit, as well as any "gotcha" items I may want to include in the lease - such as itemizing penalties or consequences for disallowed pets, extra residents, maintenance and notifying me of problems or issues, inspections and frequency, etc. 

Your market, the type of area, the actual location of the marketing, the frequency you are marketing, the timing of the marketing, competition's use of the technique, these all will play into how many calls you get from certain strategies.

If you get to the point of doing many transactions at a high frequency with the same team then things might be a little different.  

Proper screening will reduce their frequency but they cannot be eliminated!

What's the frequency?

Is this a reasonable frequency? 

I was part of a small meetup group but I believe the meeting frequency might have been too often for the amount of investing we were doing.
