The trend of population migration into the south will continue.

Avoid high end real estate – high end real estate always gets hit first in any downturn as people migrate from more expensive to less expensive homes.

LOCATION.There are a host of subset variables to consider as well like, population growth and migration rates, job growth, the economic base, median income, rent rates etc. 

There has been a lot of migration here and money being invested here from other markets.

I agree - population density is one factor and another factor is population growth.A big state with a big population is one thing but if people are migrating to it faster than people are migrating out of it, then real estate prices/rents will go up since demand will go up.What I don't understand is how come Illinois is one of those states when I thought people are migrating out of it specially to states with lower property taxes like Wisconsin and Indiana.Anyone from Chicago/Illinois care to comment?

I think that has more impact on the net migration into Denver.  

The Sheriff sales are a great place to find a cheap property but are getting more and more competitive with the NYC buyers migrating down here.

Populations have increased exponentially (as I am sure you are aware being from O'Fallon), most of the population boom is coming from those areas migrating to St.Charles county. 

It's amazing how much it can cost to get rid of squirrels and other rodents as they migrate indoors during the colder months. 

No automatic export to QB utility; instead I set up reports and run monthly to export into Excel and then enter in QB (I no longer track tenants individually in QB, just do a single journal entry for the month's deposits with line items by property) - highly suggest setting up a brand new bank account for AF to deposit rent into - makes the migration & monthly accounting much easier.
