Hey there.Wondering if anyone can provide some advice on what kind of indicators to look for on a neighborhood level.

As @Chris Seveney there are lots of buyers for the real estate backed notes but fewer for the business only notes (without real estate as collateral). 

Properties are spending more time on the MLS, sellers are getting more motivated, and there are deals to be had if you know where to look.With fewer buyers in the market, we’re seeing sellers willing to negotiate on price, terms, and even offer incentives like covering closing costs or making repairs.

That said, the fewer units a property has, the easier it is to manage, so smaller multifamily properties can offer a good balance between cash flow and simplicity.

Personally, I find BTRs to be more predictable with fewer ongoing maintenance issues, and they tend to attract high-quality tenants.

They can't afford the double deposit, indicating they live on the edge at the moment.

Long-term tenants provide consistent income and fewer turnovers.3.Long-Term Growth: Germany’s real estate market avoids the volatility seen in other countries.

This feeding frenzy has driven up park prices and there are fewer and fewer Mom and Pops to take advantage of. 

Properties with fewer than five units are classified as residential, making the loans ineligible for sale on the secondary market through Fannie Mae or Freddie Mac.

If the only indication that he is difficult is not wanting to send his ID to a stranger on Facebook, I wouldn't blame him.
