Coming from other market places I have noticed a lack of inventory in available (not new or recently built) multi family deals. 

Values, inventory levels, rent comps, vacancy rates, construction costs etc.

The inventory of multifamily cash flowing properties is large.

Turn key providers are under immense pressure to buy properties cheap enough - as we are lacking inventory and prices go up, I would be concerned that you get offered a property that is priced out of the loaction, perhaps even overimproved.With rates that low it becomes increasingly attractive to just buy a property that has been updated by the owner - typically much better quality.

I think you will find the properties are much more affordable than what you are going to see in the bay area, and the economic and population growth of the city as well as the sheer space has allowed for the greater Sac region to grow over the last few years.I personally live in West Sac which I love because like you my family is from the bay area and its a quick shot across the causeway from my house than some of the deeper parts of sac such as Carmichael, Rocklin, or Folsom.As far as available inventory in Sacramento its pretty light and its competitive at pretty much every price point but with a good game plan and willingness to get out there run your numbers and find something you can make it happen!

Low inventory will continue to throttle supply.

A lot of investors move either closer to the city (East of 294) where there is inventory, or further to Aurora or Elgin. 

Low inventory in the residential real estate market drove the median sales price of existing homes to an all-time high in April, according to the National Association of Realtors’ April Existing Home Sales report, released Thursday morning.According to the monthly survey, the median sales price reached a new high of $286,800 in April, up 7.4% year over year.

Concerns: Not in the city proper[My gf is interested in getting the 'city experience'], lack of inventory, especially duplexes)-S philly (Positives: looks like lots of inventory, cheaper houses, known for being safer than N philly.

The inventory is very low and the mortgage rates are still low too, thus increasing the demand.
