( I see $3,500 on their site)What else is there after?

US stock market, aka MAG-7, have outperformed 12% to 9.5% with REITs in last 10 yrs and even more strongly in last 5 years at 15.7% to 10.3%, perhaps this will continue but the sp500 currently with a 34.4 Shiller PE, which is much higher than in October of 1929, and that wasn't the best time to start investing, please read the following 1 article and then the graphs/tables, There are also multiple academic studies at the European real estate research site EPRAREITs vs.

Are these good sites to see or threatening? 

Below is a cut/paste from a site I found.

+95% of agents only have experience dealing with owner-occupied transactions - which are mostly EMOTIONAL decision based.You can ID these types of agents easily by asking them:1) If they are RE investors themselves.

There isn't anything on their site about umbrellas which is what the original question was about. 

Then the association passed a rule that you couldn’t rent out the downstairs as an owner, so you had to live there in the basement if you wanted to rent part of your unit and could only rent the upstairs.

As far as getting best rents, I've seen professional photos make a huge difference and depending on your local market placing it all the typical property sites like Zillow, Trulia, etc.

I'm not able to find this on a site like FRED.

Trying to find my way around the websiteI can see that this site is primarily in the USA.
