Not buying is really a pretty easy way to get a nice return without the tenants, toilets or trash. I sell a lot of houses, but I tell my investors that have liquid cash to consider just buying a note from me, it is WAY less moving parts. Especially since they are performing first position notes with low LTV.
Anyhow, the question about why folks do not take action is a GREAT one! my believe is that it is one of a few things that could cause it.
1. Lack of resources.
2. Focus- In today's world, there are SOOO many distractions. "shiny objects"
3. Lack of belief.
4. People get interested in real estate then realize there is some work involved and life just gets in the way. It is way easier to get back on the path that you know so well and not cut through the brush and blaze a new trail, but the problem is that although it is easier to go back to what ya know, that path leads to the same unfulfilling results they have always received.
Just a few of my thoughts from the top of my head.
Just think of what this business would look like if EVERYONE that started in the business is in it and active!
