@Mark WalkerIt truly depends upon the market.

I am partial to the midwest for cash flow and good appreciation if you pick the right market.

Maybe have them do your marketing. 

The only other way to get this info is to run rent/lease comps yourself (~10-15min), or do enough projects in that area to where you have it.Or for Thousand Oaks, etc:Or if we have a choice between two projects in different markets, I can use this chart to compare the two rental markets:-Basically anything to the right of 0 means the rent price/sf/mo has been growing QoQ, and the height is the current $/sf/mo of that market. 

Here in Reno, NV area the new construction has been appreciating faster that the market in the last 6 months. 

But you’d better be careful—there’s a lot of problems being dumped on the market. 

Even more challenging is ignoring that inventory of 20,000 homes on the market and sourcing off-market deals.It's true that with a good deal, money will follow.

If you find one who has rental properties and has first hand experience that can be VERY helpful.The conflict of interest is a common question, but really a non-issue if you consider the size of the market and how many properties an agent can buy.My team and I work with a lot of investors and yes I personally buy a handful of properties every year, but there are about 30,000 transactions every year in Milwaukee.

These companies are typically called "markets". 

You market the service across the Internet; nearly every time you post there's a reference to try to generate interest.
