There is a shortage of Section 8 houses in my area (Upstate SC) People are on waiting lists for as long as 2 years.

You will find no shortage of complaints on this board but most of the complainers refuse to acknowledge their share of the blame.

Rental rates - I'm less concerned about this in our Portland market as rental prices are pretty sticky and we still have an overall housing supply shortage, especially in the single family market.

Some can of course be found in DC, specifically in Trinidad, Brentwood and that general vicinity of the city....but the highest and best use of those properties is to be converted into condos, which they are and which further exasperates the shortage of MFHs. 

There's certainly no shortage of wholesalers in Atlanta, but you probably don't want to be flooded with deals you can't use.

The biggest problem we have here is the huge housing shortage we have and the city of Eugene hasn't expanded the urban growth boundary for 40-50 years!!!

I am finding shortages too. 

If you have the money and don't have to wait for insurance move very quickly because there is going to be a major shortage of housing?

With the shortage of quality houses in the tampa market it lends itself to be very successful in the next few years.

If I might share, personally I think the shortage of inventory for those of us who work seller direct will be best overcome by continuing to grow our connections, network, and online social influence and not just trying to go it alone.
