What data provider has historical tenancy information?
I am looking for historical tenancy information like tenant name, length of lease, lease type etc. For each property, I need to see occupancy and tenant history. What data provider has this data? 

Reonomy, RCA do not have this.

I've been quoted 25k for REIS nationwide and something similar for Yardi all market access.\n\nIf multifamily, one way to bootstrap occupancy data for free is by checking your comp list against properties [apartments.com](https://apartments.com) and make an effort to count available units. Not the best but that website is the base for CoStar. If commercial you may be SOL but you might try the way below:\n\nFind recent Broker OMs of similar properties to yours and draft off of their comp data. You'll need to signup for the data rooms of the big brokerage houses and access their listings. On their end, they may check credibility before approving access (not verified) so if you have an RE company email when signing up that might be better.", "replies": [{"id": "gofqvk6", "text": "Any idea where to start to sign up for data rooms of big brokerages?", "replies": [{"id": "gog38py", "text": "Start at CBRE Deal Flow.
