The idea of putting eggs in one basket (season) does tend to intimidate me.  

They also tend to have lower tenant turnover and simpler management.

We experienced real estate investors tend to look at most “guru” type training/mentorship as, at the very best, inadequate to provide the new investor with a reasonable pathway to success.  

The no-show rate for prospective tenants in this area tends to be quite high.

Properties with no mortgage tend to be lawsuit targets. 

In my experience, these are the guys that want draws all the time (and it is easy to get ahead on them based on percentage).I tend to avoid the guys that can "start right now".  

We see it in our market here in College Station, Tx. also... the bigger properties do really well during our peak season but tend to be pretty stagnant during the week and sometimes even the weekend during our slower season.

If it’s the cost of 3-4 months of electricity it’s probably pretty reasonable as my 1 bedroom units tend to run $35-$45 per month.

I suspect these things tend to snowball on top of things, wherein funds start cracking and you have to keep running faster and faster to keep a roof over your head and everyone paid.

Personally, I don't mix men and women tenants but I know some people do.
