The "high appreciation rates" you mention should be verified with recent data and be specific to the neighborhoods you're targeting.

If you want to understand 5-year outlook, I'd look for multifamily construction data in your area to understand what level of new units is and will be coming online in the near future. 

I have some data that I would like to share with you.

I appreciate the condo board’s efforts as a unit in a predominantly o/o complex is worth more to other o/o buyers, but it has to limit my buyers.  

Cody's link appears to be the Carissas and Colorado apartment complex land that D32 Builders is trying to sale.

With all respect to AirDNA and the amazing data they provide for STR owners, their pricing tool is not on par with most tools available there. 

Then I started to contact brokers that bought and sold Apartments complexes and proceeded to 1031 exchange all my Condos for Apartment complexes and told my story on BP Podcast 238 in 2017.  

Any time you transact with a traditional currency it goes through a very complex series of checks that ultimately are centrally controlled by some government.

The other tip I would say is really get a good relationship going with a realtor in the area if you do not have one to give you the exact data you are looking for to be successful.

I've been researching servicers and building data on a very small list.
