depending on the size of your complex and location you will have to get a permit from you state Department of Natural resources. 

It can get pretty complex versus long term rentals - I'd highly suggest using tools like AirDNA that has pretty sophisticated data and projections on STRS in every market before pulling the trigger

@Michael DevensHi Michael,Would you be interested in a Limited Partnership on a multi tenant industrial flex complex?

This whole situation on scale of 1-10 on landlording pain/complexity scale is a 2.5.....

Cons might include increased inspections and regulations, potential for property damage, and the possibility of dealing with tenants who have more complex needs.

You can see how this gets complex quick.On Building Big Infrastructure in the USAAnd, if I may be so bold, a note on larger infrastructure that obviously affects the real estate economy: What about large infrastructure project that get bogged down in litigation?

It depends on the number of Units, Residential or Commercial, Apartment Complex or mix of Single Family and Multifamily.Under 25 unit  - Tenant Cloud, RentechUnder 100 - Then Doorloop/Buildium.100+ - AppFolio, Yardi, Rent Manager.Apartment Management : Yardi seems to be wildly usedSingle Family ( Mixed ) - AppFolio seems to be popularRent manager has a good customer support team.

Here in Oregon we aim for 25-35% down for owner carried complexes.

Fees for this service can vary depending on your location and the complexity of the transfer.

My North Oakland units, purchased 2015, are all condos in a single complex = no rent control.
