Of course this is a subject I'm not expert in and need to learn more about, however my initial thoughts beyond addressing affordable housing and gentrification are injecting capital into those communities, improving access to education and occupational training, and encourage entrepreneurship.

Just thought I'd inject a little humor (perhaps only a little, sadly), and try to answer the question.

Pick it up - e.g. concrete injection; 2.

An admitted partner is generally required to inject capital for the stock as valued, there can be arrangements where ownership is given for management activities for example but I'd not do that as an existing stockholder.A nickel's worth IMO. :)

Pressure treated on the other hand is injected with preservatives and chemicals at high pressure driving the moisture in.  

just got a nice cash injection so probably not much wholesaling for now.

Inject a personal anecdote, tell a joke, invoke a story from your experience.

As a matter of fact, since 1989, 1.6 trillion euros were injected from the federal government and private German firms into eastern Germany.

Those are the type of businesses that appeal to me and not ones that opened 4 years ago and sales were great but now sales are down and they have a very high lease payment with the landlord they can't get out of.The problem with leasing is that over the years just as the rent options kick in you now are having to inject capital in the business to update technology and the new look to keep business coming in.

The real issue is that if rates rise, cap rates rise, property values fall and all of a sudden a 70% LTV loan that should be easy to refinance becomes an 85% LTV loan that can't be refinanced without injecting some equity.
