Are there people that can benefit from my help?

As for the HELOC, the more I research the more it matches your comment regarding using it for home improvements / flips so I may sit on that for a little bit until I educate myself further on those topics.As for raising capital, I have read the private lenders are a popular way and hard money loans which I do not fully understand yet.

No one really talks about this but they should because a lot of people get stuck buying a new fancy home and then in 12-24 months they are under water.Again not everywhere but in a lot of places where you see a small phase of builds go up and then it’s off to another city or county.The other thing that is not talked about much is home prices if the home price is under say $200K the builder loses interest.

Don’t you guys understand what the OP is asking?

Understanding the local market, neighborhoods, and community dynamics can provide you with a valuable edge in making informed investment decisions.

The people involved have a particular amount of assets(equity) and no or negative monthly cash flow. 

Right, I understand that.

Pay attention to the number of times that people have sold the house.

Hearing it from people with more experience just hits different. 

A lot of people in California have been looking at investing out of state in more landlord-friendly markets where they don't have rent control and it's easier to evict non-paying tenants.
