We handled everything in-house from the point that we acquired the properties to listing them on our website and pushing them out thru an internal sales force that did outbound calls to investors.

I went to the site and submitted some info and it says "check your email for further steps."

Listings are on their own company web page or one of the mls type listing services.

What are the metrics for determining site selection?

Quote from @Gary Aragon: Quote from @Rick Albert: Our electricity is already separate and we designed our ADU to be all electric so no gas. 

Anything smaller may not attract larger investors or offer the economies of scale needed for profitability.Design Style: BTR developments often consist of attached townhomes, usually with features like garages and a more upscale design to appeal to renters looking for something between an apartment and a single-family home.Location Factors: The success of your development depends heavily on location.

.- if buying out of state, this brings about more risk since you're not there on site.

Do a search for Background Checks on the Passive Pockets site.

We do a pretty good deal of site selection with data behind it and use experian as a data source. 

Depending on the state, you will need a designated agent for your LLC, in that state.
